Why Men Need More Than One Pair of Glasses

By Des Taylor

 

Most men who wear glasses have one pair that is their go-to eyewear. Like a pair of favorite shoes, these are the glasses that get picked up for every day wear and seem almost like a part of his personality. But the reality is that having just one pair of glasses is often a poor choice as different frames can meet your different daily lifestyle needs and whims.

Activities

No one thinks twice about buying special shoes for their exercise regime, so why not consider special glasses? For highly active men in physical sports, prescription goggles or even prescription safety glasses can be worn to protect their eyes during exercise. Eyewear that is tailored to your preferred activity can help reduce eye strain or danger to the eyes and potentially improve your game performance. After all, if you're trying to hit a baseball in the afternoon sun, prescription sunglasses to cut the glare might make it easier to see the ball.

For specific sports, consult with your optometrist or optician to find the best type of eyewear to protect your eyes and enhance your performance. Men who work with tools may also want to consider prescription safety glasses for those times when they are handling a drill or saw.

Disasters

Not getting the right eyewear for the right activity can result in glasses disasters. A lost screw can result in a dangling ear piece and glasses that won't stay on your face. Dropped glasses or an elbow to the face in a game of one-on-one basketball can break or bend frames making them difficult or impossible to wear.

No one wants to think about what happens when their glasses break, but the likelihood is that no matter how careful you are, at some point you'll end up with broken glasses. Having a spare pair can prevent the hassle and cost of getting an emergency replacement, especially when the breakage happens on a Sunday afternoon or far from home.

Fashion

Men may also want to consider a second pair of glasses for fashion reasons. Glasses that are appropriate for an afternoon of sailing or a night at the club might not be the best ones to wear to the office on Monday. The glasses for hanging out with the guys at the ballpark may not be the same ones you want for taking a date to dinner.

Men's eyewear no longer consists of the same three frame styles our grandfathers had. Make an appointment now and visit your local optometrist for an updated eye exam and then take a look around for a couple of new pairs of glasses. An extra pair or two to meet your lifestyle demands are just what the doctor ordered.

Macular Degeneration and Vitamins

By Dane Swanson

 

You have a family history of Macular Degeneration. Your grandfather had it. Your father had it. Chances are that you have the makings of Macular Degeneration. In fact your optometrist has said that he has noticed some drusen. Drusen is aging spots.

 

There is no cure at the moment for this disease. With Macular Degeneration your macula gets clogged with materials that clog and start to block that portion of your eye that is meant to give you clear and sharp central vision and color definition.

 

It can't be fixed with lenses and as it progresses can take sixty to seventy percent of your vision. It is not total blindness but close to it. It is not known what causes it.

 

It comes in two types: dry and wet. Whatever one you may have it is a case of the retina clogging with material that cuts down on your central vision making it hard to read fine print. In the last stages it is like a solid fist in the center of your vision yet you can still see on the sides of your vision pattern

 

Let me suggest a way to combat this.

 

You can improve or slow or even stop this Macular Degeneration. There is growing evidence that the use of vitamins, mineral and herbs can help fight Macular Degeneration. It is not a cure-all or a panacea but if you do nothing it is one hundred percent certain that Macular Degeneration will overtake you.

 

First of all you must know that a macula is thin and fragile and it is located at the center of your retina. The problem comes when the macula starts to die because undigested materials gather and clog the cones in your eye. No signal can be sent through a part of the eye where the macula is not functioning. You start to see wavy lines. This is dry degeneration. I will not get into wet degeneration. You get the idea.

 

So what can be done? I earlier stated something about vitamins and herbs and minerals. This is just one of the possible ways you can slow down the process.

 

The first line of defense would be vitamin C. Vitamin C will help prevent the breaking of blood vessels in the retina. It can also prevent the growth of new blood vessels on the macula. You can get your C through fruits such as berries, lemons, grapes, plums, grapefruit, apricots and cherries which are high in a substance called bioflavonoid. A daily dose of 2,000 to 10,000 mg should do.

 

And you will need vitamin A and D. You can get these by eating fish. You should eat trout, tuna, salmon, mackerel, cod and even sardines. Any excess A you get from your diet will be stored in your liver and will be drawn upon when your eyes need the A.

 

Fish will also give you your Omega-3 fatty acids which seem to decrease blood clotting which will help in the flow of blood to the eye.

 

Vitamin A is good if you can get it in some form of beta-carotene.

 

You will also need some magnesium as this help in the blood flow to the eye. Magnesium also will reduce muscle spasms and maintain a proper fluid balance in the cells.

 

Another vitamin that helps in the health of the eye, and that is what this article is about, is vitamin E.

It helps against leaking of the blood vessels. A form of vitamin E called alpha tocopherol is layered across the retina. Where it thins out is the spot where Macular Degeneration will begin. About 800 IU daily will help prevent this.

 

There are two pigments in your eye that are what you use as sun filters helping in cutting out blue light from your central vision. These two yellow pigments are vital. They are known as Zeaxanthin and Lutein. Without them Macular Degeneration can set in and increase. They can be gotten from spinach, collard Greens, turnip greens, mustard greens and kale. Or they can be gotten from a supplement of eye vitamins.

 

Since the macula needs to be refreshed by the blood flow you should also include selenium to protect the cell membranes in the retina. The amino acid Taurine will also be helpful in keeping the eyes in good shape and the blood flow sufficient.

 

You also need for good eye care the supplementation of Zinc and N-acetyl cysteine along with some hydrochloric acid. Always eat something when you take it.

 

You will also need a good multi-vitamin to get it all and then some.

So there you have a short article on an important subject.

Lasik Eye Surgery Procedure And Their Cost

The Lasik eye surgery will correct refractive errors and might therefore treat myopia (nearsightedness), hypermetropia (farsightedness) and astigmatism. This surgery will reduce the dependency of patient on contact lenses and glasses. Refractive errors have an effect on the focusing ability of the attention and therefore patients who are suffering from these conditions expertise blurred vision along with other eye issues.

                              

As doctors take away a predetermined quantity of corneal tissue throughout this surgery and reshape the cornea of the attention, it ends up in improved focusing power of the attention and enhanced visual acuity of the patient. Lasik eye surgery value isn't lined by insurance because it may be a corrective eye surgery.

Surgeons usually don't suggest Lasik on kids. Extreme cases are also thought-about as exceptions to the rule. Human eye isn't absolutely developed till adulthood and therefore Lasik Surgery in Delhi is often performed on adult patients. There ought to be no eye infection like herpes, no injury, no autoimmune disorder like lupus, no scarring of cornea, no pregnancy, no 'dry eye symptoms' before the surgery, if you would like yourself to be thought-about as an honest candidate for Lasik. Your vision should be stable for a minimum of one year before the surgery and your pupils shouldn't dilate beyond seven millimeters within the dark, for the Lasik surgery to be performed. Your ophthalmologist can justify you all the risks of the surgery and therefore the value of the surgery.
You should have realistic expectations relating to the results which will be achieved.

Cost of Lasik Eye Surgery

The cost of the surgery will by the country or the place where it's performed. It's going to vary according on expertise a surgeon possesses. The advanced or latest technology used throughout the surgery and therefore the degree of your refractive error are also responsible for lowering or raising Lasik eye surgery cost. Average value of the surgery will vary anywhere from $500 per eye to $3,000 per eye. A less skilled ophthalmologist could charge a lower Lasik eye surgery worth, however you should not select a Lasik surgeon staring at the worth of the surgery. He/she may well be lacking within the expertise, coaching or precise equipment that a costlier doctor may well be having.

The cost of the surgery will increase in step with the size of the city! In larger metropolitan cities, patients have to be compelled to pay more; as a result of there, the doctors try and keep previous their competitors by utilizing the most recent laser technology. However, it's observed that the typical value of Lasik eye surgery within the country is comparatively consistent from region to region.

Lasik value Breakdown
The cost of the surgery could or might not include any of the following:
* Anesthesia value
* Rent for surgical and workplace facilities.
* Purchase and maintenance of surgical and technical equipment.
* Different sterile and disposable materials.
* Post-surgical enhancement and eye care if needed.
* Pre and post-operative evaluations for sometimes up to at least one year once surgery.
* Medications used before, throughout and once surgery, eye drops, pain relievers and oral medications.

Higher value of the Surgery

The type of laser and therefore the technology used to determine the cost of the surgery.

* Lasik surgery that involves the utilization of a laser instead of a microkeratome blade to form the corneal flap, prices between $250 and $500 or a lot of per eye.

* Custom Lasik, whereby wavefront technology to map the patient's cornea is concerned, will value between $200 and $500 or a lot of per eye.

Patients ought to analysis completely whether or not these new techniques are worthwhile or right for them. Sometimes, with aggressive advertising campaigns, Lasik eye surgery worth discounts are announced. There are numerous ways to usher in a lot of customers. Patients ought to check the foundations or clauses, costs excluded, etc., before accepting such offers. Here, I conjointly need to say that paying the next worth doesn't essentially guarantee that you just can get the most effective Lasik surgeon. You ought to pay ample time researching the most effective skilled, experienced eye surgeons who use advanced technologies and supply best facilities in your space.

As seen above, Lasik Eye Surgery in Gurgaon value varies in step with location, the technology used and different factors specific to every patient moreover as surgeon. So, it's necessary for the patients to completely analise what they're paying for, before undergoing any surgery. The patients ought to request the doctors to clarify what is and what's not included within the surgery value, before agreeing to any payment plans.

Short Sightedness Treatment That Can Save Your Sight!

Short sightedness treatment is becoming a key issue in our modern society due to the marked increase in short sightedness or myopia, particularly among the young and teens. With the rise of ipods, iphones, computers and the internet the sad fact is that we expect to see myopia increase, and most Optometrists seem powerless to offer any short sightedness treatment that can limit the growth of the condition.

                 
Traditional Treatment Makes It Worse!

Traditional Myopia Treatment usually involves distance glasses of contact lenses, both of which frequently cause an increase in the short sighted prescription, notably for 7-21 year olds. The result is full time glasses, thick lenses and the risk of numerous and often catastrophic eye issues like retinal detachment and macular degeneration!

When traditional lenses are prescribed, they should be used for distance purposes only, and studies show that any reading done through the lenses (copying off the board for example) will tend to increase the short sightedness prescription, meaning that every trip to the Optometrist yields stronger and thicker lenses.

Parents who are short sighted are up to 5 times more likely to have short sighted children, so continuously making the distance prescription stronger and thicker is a very real problem.

Why Does Most Myopia Treatment Make it Worse?

The fact is that traditional short sightedness treatment only corrects the condition after is has happened, it does not stop it from getting worse! In fact, correcting the condition can make the progression into short sightedness faster, which is exactly the opposite to what we want to do!

I was very unhappy as a Optometrist about seeing short sight increasing in my young patients, but for many years now I have been pursuing Short Sightedness Treatment that actually slows, stops or even reverses that shortsightedness in children.

Despite our near centered environment, using state-of-the-art technology and ideas we can now provide short sightedness treatment that stops the progression into thicker lenses, and at times even reverses it!

Short Sightedness Treatment That Stops the Progression

I have two tools which are yielding stunning results in controlling the progression of myopia. The first is the fitting of special bifocal glasses, and the second involves a specialized form of contact lenses.

Both techniques are firmly grounded in science, and have an amazing track record as myopia control treatment that actually slows, stops or even reverses the slide into myopia that many children face today.

So if you are shortsighted, please do not settle for tradtional Short Sight Treatment. Find a Behavioural Optometrist and save your child from the distance blur that you suffer, and the earlier you do it the better results we get!

Don't settle for pushing your child into full time glasses! Avoid the old fashioned distance only treatment and discover the short sightedness treatment that can save your child's sight!

Importance of Eye Care

By Julie Staz

 

Eyes are the most wonderful creation of God and therefore are to be taken care of at all times. This is an extremely beautiful gift and should never be taken for granted. Whether or not you have any vision related problem, eye care should remain an important part of everyone's life.

Many people suffer from eye diseases which have been getting quite common in today's world. Some are viral while some may have other reasons for developing them. It is not true that eye diseases cannot be prevented. They can surely be treated but they can also be prevented. Hygiene is the most important thing to consider when it comes to eye care. The eyes should stay clean at all times and one should avoid touching them with hands because eyes can sometimes be very sensitive to the germs we have on our hands at all times. And if you are a woman, make sure your eyes are free from make up when you go to bed. It is a lot better to rinse your eyes and remove all make up such as mascara instead of just sleeping like that.

Because eye treatment can be very expensive and can cost a person a lot of money, it is important to take notice of your health so you can prevent some of the eye diseases and even slow down their progress if you have already got one. For this purpose, you should increase your intake of vitamins such as vitamin A, E and C. Zinc and Selenium can also do the job rightly. Eye diseases can also be a result of some other disease. People with other problems such as obesity, diabetes et cetera should have regular checkups for their eyes and should immediately go to see a doctor if they feel anything unusual in their eyes. Most of the eye problems are also a result of exposure to certain types of light or direct sunlight. You should always wear sunglasses when going out in the sun; just like the sun can harm your skin it can likewise harm your eyes which are way more sensitive than the skin. The exposure to light also includes frequent watching of the TV or sitting in front of the computer screens. If you are someone who cannot avoid using the computer, probably because of some work or something, then you can try other methods of eye care. Try sitting away from the computer or laptop screen and there is a certain distance which you should keep. Protective shields are also available for the computer screens which can be very useful in filtering direct light from the computer screens.

People with frequent problems such as infections should keep eye care as their priority. Eye infections can be caused by bacteria, germs on the hands or even fungal elements which cannot be seen. Viral infections are also threatening and should be treated immediately with care. Eye infections can occur in both the eyes; left and right. They also affect people from all age groups and their symptoms will vary. You will know you have an infection when your eyes feel watery, itchy and irritable. If the problem is not treated it can also affect the vision on a temporary basis and will cause redness and swelling around the eyes.

Sleep, being very important, also plays a vital role in the care for eyes. People not sleeping enough will start having puffy eyes with dark circles which can become a permanent part of their face. Moreover, tired eyes are more prone to vision difficulty and concentration problems.

What Is Macular Degeneration And Its Two Forms?

 

 

By Rachel Berret

 

You know that with age comes a variety of health problems. There are cases of osteoporosis, muscle spasms and the very serious heart condition. These are actually diseases that are caused by the weakening immune system and other bodily structures inside your body. They can no longer support the activities that you very do with much energy when you are younger.

One part of your body that is very well affected by aging is your eyes. True to form, the usual problems encountered by the elderly are loss of vision and poor eyesight. Macular degeneration is a disease that progresses with age and that damages the macula. This part of your eyes is in the central area of the retina, which is responsible for the clarity of your vision.

When you have macular degeneration, you experience seeing blurry pictures and distorted images of your surroundings. You cannot read clearly because the words look jumbled together. You would also find recognizing people's faces and even the features of various places as difficult due to blurred spots in your vision. Even if you would not likely go completely blind because some parts of your vision, like the periphery, are retained, having macular degeneration is still impairing because it deals with the major aspect of your eyesight.

There are two forms of macular degeneration: dry and wet. If your condition is that of the dry form, drusen-yellow deposits that hinders the macula-develop in a slow manner. Therefore, you would only feel its manifestations when the drusen is already growing. The cells in your macula also get thinner, which leads to the death of the tissues in your eyes.

If on the other hand you have the wet form of macular degeneration, abnormal blood vessels grow under the retinal pigment epithelium layer. It leads to bleeding and leaking that in turn causes scarring. Then, your eyesight transcends from having blind spots to finally losing your vision. This is a condition that develops rather faster than the dry form.

So how do you prevent macular degeneration? Definitely, you need to know the risk factors involved so you can avoid them. Age and heredity are the primary risk factors. But smoking, obesity and exposure to too much sunlight can also put you at a great risk of having the disease. You also have to be on the lookout if you have a case of cardiovascular problem and hypertension.

Disease - Proof That A Natural Extract Can Stop Eye Disease

By J Michael Brown

 

A scientific study showed how it's possible to stop eye diseases. It is definitive proof that a naturally occurring substance could help stop some eye diseases.

A press release of July 31, 2007 by Sirtris Pharmaceuticals, Inc., which is a biopharmaceutical company based in Cambridge, Massachusetts and listed on the NASDAQ stock exchange as SIRT, focused on how it discovered a means to facilitate anti-aging; and specifically how to stop optic neuritis.

The findings, which presented definitive proof that eye diseases may be stopped with a naturally occurring substance, appeared in an article entitled "SIRT1 Activation Confers Neuroprotection in Experimental Optic Neuritis, Shindler et al., 2007" that was published in The Investigative Ophthalmology and Visual Science Journal (IOVS), Volume 48, Number 8.

Optic neuritis is an eye disease, which affects the optic nerve comprised of axons emerging from the retina of the eye. The optic nerve carries visual information to the main visual nuclei, of which is primarily relayed to the outer layer of the occipital lobe of the brain; where the brain processes information into vision.

Swelling of the optic nerve can result in loss of vision more often than not because the inflammation results in destruction of the myelin sheath, which covers the optic nerve. Uninterrupted axonal damage often plays a role in neural destruction.
 Optic neuritis is commonly linked to conditions including:

• Autoimmune disorders,
• Multiple sclerosis,
• Huntington disease,
• Infections, and
• Granulomatous diseases.

The scientific study at Sirtris showed, that by developing small molecule interference, eye diseases could be stopped. Sirtris hopes that he substance used in the scientific study will be approved by the FDA to treat diseases related to aging like Type II Diabetes and Macular Degeneration.

The scientific study showed that activating the SIRT1 gene, which is an enzyme in the sirtuin family, with SRT501 (resveratrol); optic neuritis be relieved. Sirtris presented pictures related to the microscopic analysis of the optic nerves of mice, which they performed; after the mice initially were induced to have optic neuritis, then anesthetized--and finally the mice had the nerves leading to the occipital injected with the SIRT1 formula.

Sirtris offered the results of the experiment as definitive proof that resveratrol could be associated with anti-aging, and that their SIRT1 a formula was a debilitating factor when used to deter some eye diseases.

Resveratrol was the agent to which the scientists assigned credit for activation of the anti-aging gene SIRT1 in mice; and they took it one step further by inferring that humans could generally, and conveniently, become accustomed to the adaptation of resveratrol as a neuroprotective agent against optic neuritis.

Therefore, Sirtris offered the study as proof that eye diseases associated with optic neuritis in humans could be stopped too, simply by using resveratrol.

The gradually loss of neurons associated with age may bring about a various debilitating neurological disorders, one of which is optic neuritis. One of the initial signs of multiple sclerosis is optic neuritis, and it's been associated with a reduction of mitochondrial function.

Sirtuin, which is a new class of enzymes and only recently discovered, appears to influence the aging process in test mammals, and Sirtris offered the study under review as proof that it increases the number and fundamental operation of mitochondria.

According to results of the scientific study, resveratrol is an SIRT1 activator and it fundamentally deterred losing retinal ganglion cells in test animals; thereby preserving axonal function in a pre-clinical model of optic neuritis.

A single intravitreal injection of SRT501, which is the proprietary resveratrol formula developed by Sirtris, was adequate for neuroprotection. What's more; the neuroprotective effect was proof that activation of SIRT1 was the reason for the significant results because that was how sirtinol, which is a SIRT1 inhibitor, was blocked.

Peter Elliott, Ph.D. said, "This work is significant because it shows that a SIRT1 activator is neuroprotective and thus has the potential to be therapeutic for a range of neurodegenerative diseases of aging."

Christoph Westphal, M.D., Ph.D., who was the Chief Executive Officer of Sirtris Pharmaceuticals, Inc. until April 2010; added, "These new data support our belief in SIRT1 as a therapeutic target for a broad range of diseases of aging including metabolic, mitochondrial, and neurological disorders."
Sirtris Pharmaceuticals, a biopharmaceutical company, is focused on inventing and developing proprietary small molecule drugs, which can be administered by physicians via intravitreal injection; and the research project under review in this expose' concerns their SRT501 resveratrol formula.
Whether or not Sirtris plans to make their SRT501 formula available as an over-the-counter supplement remains to be seen.

But the question, which will remain unanswered in this editorial; is, "Can over-the-counter resveratrol stop many of the diseases that are associated with aging simply by taking a capsule of it once or twice a day, without a prescription from a medical doctor?"
 Some of the diseases, which need to be considered in a future scientific study that could provide proof that such a miracle capsule would really work to stop eye diseases, include metabolic disorders such as:

• Type 2 Diabetes,
• Alzheimer's disease,
• Optic neuritis, and
• Macular degeneration.

The study wouldn't be limited to those diseases specifically, but it will look at overall general health of individuals.

People who would like to be candidates for such a study would have to understand that the nutritional supplements, one of which would include an over-the-counter formula with a substantial amount of resveratrol, would be formulated to mimic beneficial health effects that'd ultimately be equivalent to calorie restriction; without necessitating a change of eating habits.

Activation of the newly discovered class of enzymes, sirtuin, is the foundation upon which Sirtris has offered proof via several scientific studies; that resveratrol is an anti-aging agent. The company's headquarters are in Cambridge, Massachusetts.

The press release, upon which this article is based; contained forward-looking statements, which were contained in it that conform to the Private Securities Litigation Reform Act of 1995. Those statements included, but they weren't limited to, potential therapeutic benefits of resveratrol; and they have proof that it is an SIRT1 activator.

The US Food and Drug Administration (FDA) hasn't evaluated the statements contained within this commentary. Over-the-counter resveratrol supplements are not intended to prevent, diagnose, cure or treat any disease.

The sole purpose of over-the-counter resveratrol is to activate the SIRT1 gene, which in theory would allow people to age normally without maladies commonly associated with getting older; so, as the scientific study discussed in this editorial shows, it's how some people might stop some debilitating eye diseases.

Anatomy of the Human Eye - How the Human Eye Works

By Tenay Brown

 

The human eye is commonly referred to as the human body's most complex organ. It contains many different parts and depends on all parts to work efficiently in order to have the best vision possible. Of all five senses, vision is the most valued and the quality of this vision is directly related to the way the eye's parts work with each other.

Basic Eye Anatomy
The eye consists of 11 basic parts, all of which have a vital role in the vision process. The basic anatomy of the eye includes the iris, cornea, pupil, lens, sclera, ciliary body, choroid, optic nerve, macula, retina and vitreous. Light enters through the cornea, which is the region of the sclera that is transparent. It provides the eye with the power to focus and is also the part of the eye where contact lenses are placed. The color of your eye, or the colored iris, is located behind the cornea and is visible only because the cornea is transparent.

In the center of the iris is the pupil, which is the dark and round opening in the center. It has control over how much light enters into the eye by dilating the size of the pupil in conditions of dim light and constricting in conditions of bright light. The lens also provides some focusing power within the eye and is located directly behind the pupil. The shape of the lens changes to bring objects into focus-such as when you are reading-and muscles contract that are located in the ciliary body. After a while, the muscles lose the ability to change shape and the lens becomes rigid which leads to a need for glasses.

Light images are converted into electric pulses by photosynthesis cells that make up the retina. These electric pulses then travel to the brain through the optic nerve. Fine detailing is accomplished by the macula, which is a specialized area that is located in the center of the retina. The clarity of vision is determined by a combination of factors: the length of the eye and the focusing power of both the lens and the cornea. Vision is clear if these three factors match perfectly together; when they do not, this creates vision problems.

Sclera
The sclera, also known as the white part of the eye, is the protector of more sensitive parts of the inner eye, such as the choroid and the retina. Most of the depth of the sclera is 0.03-inch thick, but it is no more than 0.01-inch thick where the straight eye muscles connect. There are six muscles in each eye that control the movements, but four are referred to as the straight eye muscles. The sclera is nourished with nutrients and oxygen through blood vessels located in the episclera, which is located on top of the sclera.

Choroid
The choroid provides the retina with a nourishment of nutrients and oxygen through a network of blood vessels. It is located within the sclera and is responsible for providing the anterior part of the optic nerve as well as the macula with the blood supply they depend on. When there is an abnormal growth of blood vessels, an eye condition called macular degeneration occurs, beginning in the choroid and going to the retina through the Bruchs Membrane. Because of a weaker structure, this causes edemas due to the bleeding or rupturing of the weakened vessels.

Retina
The retina is in the back of the eyeball and is the light-sensitive tissue that contains two types of light receptors: cones and rods. The cones generally absorb the stronger light and are color-sensitive, located in the retina's center. The rods absorb black and white in soft light and are next to the fovea. Retinal detachment, or amotio retinae, is a serious eye condition that produces symptoms such as light flashes or vision loss that can lead to permanent vision loss if left untreated.

Iris
The iris has control over how much light enters into the eye; the muscles of the iris sphincter with contract with strong light and will dilate with dim light. The diameter of the iris expands when focusing on an object far away and narrows when focusing on near objects-this is called the accommodation reflex. The eye color is a direct relation to the type and amount of pigments in a person's iris. Green is the least common color while brown is the most common.

Cornea
The cornea covers the anterior chamber, the pupil and the iris. It is transparent and contains two-thirds or 40 of the 60 diopters in the eye. It is supplied with nutrients and oxygen through tear fluid instead of blood vessels, which explains why it is so clear. Blood vessels can appear in the cornea though if there is an oxygen deficiency which can happen from overusing contact lenses. This can cause partial vision loss if the vessels grow too close to the center. Surgical procedures can be performed to correct eye conditions of the cornea such as astigmatism, hyperopia and myopia.

Pupil
The pupil is the hole in the center of the eye that absorbs major parts of light, which is the reason it is black. When they appear red in pictures, it is due to the reflection of the retina.

Vitreous Body
This part of the eye is located behind the lens and fills the eye with a clear and gel-like substance. The vitreous body shrinks as you gets older and can detach from the retina as the body decreases in size. Vitreous body detachment is generally not a dangerous condition, but can become dangerous if it drags along the retina.

Lens
One-third of the eye's diopters obtain their power in the lens while the remainder is in the cornea. The lens is the part of the eye that allows you to change focus depending on the distance of an object whether it is across the room or directly in front of your face. It is attached to zonula threads which are attached to the ciliary body. When focusing on a near object, the ciliary body contracts, which allows the zonula threads to loosen and the lens to increase its acuity by thickening in diameter while contracting. Cataracts is an eye condition that is age-related and results in blurry vision as the most common symptom. The treatment for cataracts is generally surgically removing and replacing the lens.

Ciliary Body
The ciliary body contains the ciliary muscle, which is responsible for controlling the vision accommodation reflex. The body is also an attachment point for the zonula threads and produces aqueous fluid.

Optic Nerve
The optic nerve is responsible for sending signals to different areas of the brain from the eye in order to create images. It consists of about one million nerve threads and the nerves from both eyes are connected behind them so that the left field of vision is sent to the right hemisphere of the brain and vice verse.

Macula
The macula consists of visual cells that are closely packed resulting in high visual acuity, or high image resolution. These cells are not as closely packed around the macula as they are inside of the actual macula, but they control how well the peripheral vision works and is good enough for it to work properly. Macular degeneration is a common eye disease that occurs among the elderly and is separated into two categories: wet and dry. Wet is more serious than dry, but is also treatable with FDA-approved drugs while dry is not treatable and is the most common.

Top 6 Vitamins And Herbs For Eye Health

 

By Rebecca Prescott

 

Tired and sore eyes can be a problem for computer users. Given the full day that many of us have, it's no wonder our eyes sometimes suffer. And they are the first place to show the effects of tiredness and stress.

In a perfect world, we would get all of our vitamins from food. However, modern farming practices and the depletion of nutrients in soil often results in fruit and vegetables having significantly less minerals and vitamins than they used to, when everything was 'organic'. Foods labeled and sold as organic these days tend to have more vitamin C, iron, magnesium and phosphorus, and less of the harmful nitrates and other residues from pesticides.

However, not everyone has ready access to organic food, or the money to buy it for the whole family.

Thus, vitamin supplements are a good option to help us get our missing nutrients.
Here is a list of the top 6 vitamins, herbs, and phytonutrients to help alleviate the problem of sore, dry eyes, and maintain good vision:

1. Bilberry - Bilberry is a herb used for both gastrointestinal and eye health. The active ingredients are called anthocyanosides, which are a type of flavanoid. Anthocyanosides are antioxidants that help improve the flow of blood through the capillaries in eyes. They help eyes adjust quickly to changes in light, and improve sharpness of vision.

Bilberry has also been shown to be effective in stopping the progression of cataracts when taken with vitamin E. It's also used to treat diabetic retinopathy, and macular degeneration.

2. Vitamin A - Vitamin A is important for good night vision, and may play a role in preventing cataracts.

3. Grapeseed - Grapeseed is good for the peripheral circulation in our eyes. It also strengthens the capillaries.

4. Eyebright - Eyebright makes a great eye home remedy. Steep it in hot water to let the herb infuse, then remove the herb and cool the remaining liquid. You could put it in the freezer to cool it down quickly if you don't have any infused eyebright on hand in the fridge. Once its cool, use it as an eye bath, or a compress. It's great for sore eyes, and has an anti-inflammatory and soothing action.

5. Omega 3 Fatty Acids - Research from Harvard Medical school has found that taking omega 3 oils reduces the chance of getting dry eyes. Try taking 3 to 6 grams of a good quality fish oil supplement daily.

6. Lutein - Lutein is one example of a type of plant nutrient known as carotenoids. Better known examples include beta carotene and alpha carotene. Carotenoids are responsible for giving fruit and vegetables their distinctive colors, and the brightness of a fruit or vegetable is a good indicator of how much carotenoids it has in it. Those with a rich color have a higher concentration.

Lutein, beta, and alpha carotene are converted by the body into vitamin A. And lutein is found in very high concentrations in the macula of the eye. Lutein is used to help prevent macular degeneration, which is a big problem for people over 40 years of age. Macular degeneration can lead to blindness.

Lutein is thought to work as an antioxidant in this capacity.

Other solutions for dry eyes include soaking chamomile tea bags and placing them on both eyes when they are cool. Chamomile helps reduce redness and swelling around the eye. Iced milk can also be used on a compress for sore eyes. Soak cotton wool or gauze pads with very cold milk (the coolness helps narrow blood vessels), and the fat in milk is very soothing for dry skin.

What is retinal detachment?

By Pen Byrd

 

A retinal detachment is an eye disorder where the thin lining of tissue at the back of the eye pulls away from the blood vessels that supply it with oxygen. It requires immediate treatment and can lead to blindness if not dealt with properly.

Retinal detachments are usually caused by retinal tears and can sometimes follow an injury. A sudden blow to the head might cause the vitreous jelly to separate from the retina, so stay alert if you've been in an accident. Retinal tears can also be caused when they jelly like substance at the back of the eye shrinks and pulls against the retina. If the retina's torn, fluid can get behind the tear and the retina might peel off – a bit like wallpaper.

This is very dangerous as the retina contains millions of nerve cells which help convert light into nerve cells. If the retina pulls away from the blood vessels that supply it with oxygen the nerve signals will start to die and this can damage the cones and rods in the retina. If the retina's not repaired promptly it can lead to a permanent loss of vision.

The symptoms of a retinal detachment include an increase of fluid in the eye, flashes of light and the sudden appearance of floaters – dark spots or thin black strands that seem to float around your eye. If you notice any of these warning signs it's important to see your optometrist urgently. Some patients describe a curtain coming across their vision, so be sure to look out for changes to your vision.
If you think you've a retinal tear, an eye care specialist will normally place drops inside your eye to dilate your pupil and will examine your retina. They will check for tears or detachments and if they see a problem they'll refer you to a retinal specialist.

Retinal specialists are able to repair a tear using a special laser and this usually takes place under a local anaesthetic. If a retinal attachment has occurred you'll need surgery to correct the problem. The longer the retina's cut off from the blood supply, the more damage will be caused, so it's essential to act quickly. Never ignore symptoms and always seek help if you experience any changes to your vision.

The retina can become thinner and brittle with age, so it's essential to see your optometrist regularly. A highly-trained optician will be able to spot the early stages of retinal detachment (if present) and will also look out for other eye conditions such as glaucoma, cataracts and age-related macular degeneration.

Our eyes are extremely delicate and must be examined often – so book your eye test today!

LASIK Laser Eye Surgery Explained!

 

Over the last number of years, the world has witnessed amazing advances in the field of medicine, especially with the advent of LASIK laser eye surgery. This revolutionary procedure has both given hope and excited those who experience problems with their eyesight.

But what exactly is LASIK eye surgery?

What happens during LASIK laser surgery is that the lasers correct refractive errors in the cornea. The laser perfectly controls the tearing of the corneal tissue, thereby reshaping the cornea and changing its focus. LASIK surgery follows a simple two step process:

1. A slight, thin flap of tissue is created on the outside layer of the eye or cornea. This flap encourages healing and provides comfort on the way to better vision.

2. The surgeon folds open the flap on the inner cornea to correct the eyesight. Once this is done, the flap is closed to its original position and sealed with stitches.

The word LASIK refers to Laser-Assisted In Sutu Keratomieusis, a process which is characterized by the reshaping of the cornea to refract light in the lens. While LASIK eye surgery is by no means perfect, it is a very viable and increasingly safe surgery.

Government regulations have led to improvements regarding the types of lasers to be used for LASIK laser surgery. If you or anyone you know are considering LASIK laser surgery I would advise you to carefully research the types of lasers used by your local doctors when performing LASIK.

New improvements coupled with the regulated costs of doctors mean that LASIK surgery has become more affordable, making it a possibility for some who could only dream of such improvement a few years back. Some surgeries are referred to as "bladeless" or "custom" LASIK, meaning they are more tailored towards the individual and are therefore more effective

Finally LASIK surgery is an exciting prospect to anyone who has suffered from vision problems in the past. However, just as when buying a car or house, you need to carefully consider all your options before embarking on LASIK.

Eye Sty - Causes, Symptoms and Treatment Methods

 By Juliet Cohen

 

A sty is an acute infection or inflammation of the secretory glands of the eyelids. A sty also may arise from an infected hair follicle at the base of an eyelash. It is sometimes referred to as a pigpen or "pig parlor." Pigsties are generally fenced areas of bare dirt and/or mud. It is caused by bacteria that normally live peacefully on the eyelid skin surface. It is a red, painful lump on the edge or inside of your eyelid that may look like a boil or a pimple. Also known as hordeolums, styes can be caused by different factors such as blocked or infected eyelid glands or inflammation of eyelids. Contaminated fingers that touch the eye area also can cause infection. The eyelid becomes sore. The infection may spread along the eyelid and the whole lid may become red and inflamed. If an internal hordeolum doesn't drain and heal, it can turn into a chalazion. A sty results from an acute infection of the oil glands of the eyelid that occurs after these glands have become clogged.

                 

Causes of Sty

The common causes and risk factor's of Sty include the following:

An infection in the sebaceous (oil producing) or sweat glands in the eyelid.

A chalazion develops when an oil gland in the eyelid becomes blocked.

Using mascara, eyeliner, or other eye products, which can irritate the eye.     
Rubbing the eyes.

Symptoms of Sty

Some symptoms related to Sty are as follows:

A painful, red and tender lump develops on the eyelid.

Tiny, yellowish spot develops at the center of the swollen area.

Eye becomes sensitive to light.

Swelling of the eyelid.

Tenderness.

Sometimes the infection drains and the eyelid returns to normal without treatment.

Treatment of Sty

Here is list of the methods for treating Sty:

Most styes will drain on their own though this may be accelerated with a hot or warm compress.

Use make-up remover rather than just soap and water to remove eye make-up. This prevents heavy rubbing of your eyes and more completely removes the make-up.

Although antibiotics are sometimes used to treat styes, they do not really help much.

If a style or chalazion gets very large, the doctor may need to pierce (lance) it so it can drain and heal.

An antibiotic ointment may be prescribed if the stye does not clear.

Paracetamol will also help relieve the pain of a stye.

A stye does not begin to improve after 3 days of home treatment or does not heal in one week.

 

Red Watery Eyes - 7 Effective Steps to Cure Red Watery Eyes

By Angela Lim

 

Red watery eyes are usually called as conjunctivitis or pink eye. Conjunctiva is a slender lucid layer with the aim to cover the visible part of eye sclera and inner part of eyelids. As soon as conjunctiva gets inflamed, its tinny blood vessels expand in this manner causing emergence of red or else pink eye.

What are the symptoms?
o Skin complaint or itchiness.
o Blurry eyesight.
o Light sensitivity.
o Yellow discharge from one or both of eyes.
o Increased tearing.

What are the causes?
o Acute bacterial conjunctivitis.
Newborn might be infected with Neisseria gonorrhoeae from infected vagina during delivery time.
o Viral conjunctivitis.
It is usually caused by Adenovirus, transmitted by fingers, medical instruments, or swimming pools. The main symptoms are itchy eyes and watery discharge.
o Allergic conjunctivitis.
The characteristic is stringy translucent discharge.

Red watery eyes treatments are so simple to do at home. Here are the 7 effective steps to cure red watery eyes:

1. Warm water compresses help pink eye. Heat up helps for expansion of blood spring and loosen debris.

2. Rinse your eyes with mixture of pint of salt in a boiled-water cooled to room temperature. Wash your eyes with this liquid 4-5 times a day.

3. Breast milk is the best home remedy for pink eye. Bear in mind to use only fresh breast milk to cure pink eye.

4. Chamomile tea bags are very useful for natural pink eyes treatment. Moist chamomile tea bag and put it over the closed eyes for 10 minutes for a faster relief.

5. Marigold is known for its antiseptic and anti-inflammatory features. Marigold compress helps much in pink eye.

6. Avoid touching your eyes since this could lead to further infections.

7. Wear dark glasses to prevent infection to other people. Also wear goggles while swimming to avoid bacteria coming to your eyes.

Red watery eyes medicines can be prescribed by any doctor. Mostly, the medicine contains chemicals which sometimes cause your body to form resistance to it. If you overuse it, the medicine will not be effective anymore when truly needed.

The best way to keep your healthy vision is actually by using effective things found in nature as home remedies. Besides, eye exercises can be one of the best solutions to be free from red watery eyes. You are just a click away to a healthy vision.

Angela Lim has been practicing natural and simple eye treatment which can be done at anytime and anywhere. She is very eager to share her successful treatment result to everyone who is tired of buying expensive eye treatment products and desperately to have perfect vision.

Regular Eye Exams - What Does it Involve and What Does an Eye Exam Cost?

 

Even if you've never had an eye exam (and if you haven't, you definitely should rush to your nearest ophthalmologist), you probably know some of the procedures - reading a chart of increasingly smaller alphabets kept at a distance, the eye doctor plugging in different powered lenses into a large, menacing looking apparatus. As a child, an eye exam filled me with a particular sense of dread and I don't think I've ever been over that.

So what exactly is an eye exam?

It is essentially a series of tests performed by an ophthalmologist, designed to ascertain a patient's ocular health status. These tests may range from determining the strength and health of eye sight (i.e. whether you can see clearly without needing glasses), determining the power of your eyes (if you need glasses), testing for any common eye diseases, and checking for conditions such as color blindness, irregular curvature of the lens, etc.

An eye exam should be performed only by a trained ophthalmologist. An optometrist may also conduct an eye exam, but that would be limited to determining the power of your eye.
Regular eye exams are recommended by all doctors as most eye diseases are asymptomatic. Further, many serious illnesses such as diabetes, hypertension, etc. may manifest themselves as ocular defects. Thus, they may help in diagnosing other serious diseases early, paving the path for easier treatment.

An eye test typically begins with an examination of the external features of the eyes, such as the eyelids, the cornea, sclera (the white part of the eye), etc. After that, the examination moves into a visual acuity test (i.e. a test of the eye's power and ability to focus on near and far objects - the test you are probably most familiar with).

The next test is a Pupil function test to determine the health of the pupil and detect any damage (physical, neurological etc.). After this, an eye exam may include a test of ocular motility (i.e. testing the eye's ability to follow quickly moving objects, usually carried out when patients complain of double vision), and a test of the visual field. There may be several other tests depending on your own ocular health.

Eye exam costs may differ from state to state and city to city. Typically, an eye exam may cost anything from $50 to $300 depending on the range of tests done. Costs may be even higher if a patient is found to be suffering from any serious ocular condition that requires extensive testing.
Many people tend to ignore regular eye tests, despite maintaining a healthy lifestyle and getting regular complete body check-ups. As I've said before in this article, these can often reveal the existence of far more serious medical conditions, so it is imperative for the sake of your eyes as well as your body to get undergo regular eye tests.

Retinal Detachment - Causes, Symptoms and Treatment

By James S. Pendergraft

The retina of eyes is attached to the tissues which lie under the eye and the separation of the two is known as retinal detachment. The common causes of this situation is the breakage of the retina or the tearing of it. The breakage of the retina may be caused by the detachment of the vitreous gel from the retina. The two their part of the eye is filled with the vitreous gel and it is this gel that covers the entire retina and if the strength of the retina is fragile, it leads to its breakage. If the blood vessels in the retina are present in the breakage, it causes bleeding of the eye. However, most of the retinal detachments that happen are not a cause of injury.

If the retina tears, it gives way to the vitreous gel to get into the back of the retina. It is this layer of accumulated gel that causes the detachment of the retina from the eye. As more and more of the gel gets accumulated and layered behind the retina, the detachment increases and in some cases the entire retina is detached. This happens when the tear is very big. The retinal detachment is mostly prominent in a single eye. It does not affect both the eyes. When such an incident happens, even the other eye is thoroughly checked for any signs of tears or breaks in the retina. This is done to safeguard the second eye so that preventive measures can be taken.

The patient who is experiencing the symptoms of retinal detachment sees flashing lights in the initial stages. A person who has this symptom has to immediately see the eye doctor without further delay. The retina could be saved in many cases if shown on time. The effect of flashing light is caused by the loosening of the vitreous which allows the gel to get in contact with the retina. There is also the symptom where the person can visualize floaters. This is caused when the vitreous gel gets solid to even an insignificant extent. If treated earlier itself, the treatment is much more effective.

The treatment for retinal detachment is done with the help of laser therapy where the holing and tearing of the retina is treated. Another way of treatment is by freezing the retina. While the retina is frozen, even the gel freezes and it is thus prevented from layering at the back of the retina. This eventually prevents the retinal detachment in the initial stages. In other worse cases, where the retina is almost detached, a surgery is immediately performed.

These eye surgeries are of three types:
Scleral buckling
Pneumatic retinopexy
Vitrectomy

The holes and tearing that is caused in the retina has to be treated as the vision of the person is blurred or in some cases partially blinded. The impairment in the vision can aggravate and cause permanent blindness if not treated immediately. Thus it is advised to always take good care of the eyes.

Eye Allergies - Do You Suffer From Eye Allergies?

By Timothy Croy

 

What begins as a harmless piece of dust can end up causing an allergic reaction in people who have sensitive eyes. The immune system triggers a response to what it perceives as a threat and or pollen can cause excessive tearing and drainage including mucus. Eye allergies also cause the eyes to be overly sensitive and irritated feeling and can lead to conjunctivitis and other conditions such as asthma.

The Cause of Eye Allergies
Most are caused by airborne allergens. These can include mold, dust, pet dander, and pollen. Some other causes can include cosmetics and medications that are taken in the eye usually in the form of drops.

Symptoms of Eye Allergies
o Red Eyes
o Itchy Eyes
o Sore Eyes
o Watery or Tearing Eyes
o Swollen Eyes
o Runny Nose
o Sneezing
o Itchy Nose
o Itchy, Sore Throat
o Sinus Pressure
o Headache
o Itchy Mouth
o Difficulty Breathing

Eye Allergy Treatment
The best treatment for eye allergies is to avoid the causes. Staying clear of pet dander and keeping your home free of dust is a good beginning. Using a filter in your vacuum cleaner and air conditioners is another great way to keep the irritants in the air to a minimum. Avoiding dust storms and staying indoors in an air conditioned area can help to filter the pollen and keep it from irritating the eye as well.

When you can't avoid the causes of eye allergies there are medications that can treat the symptoms. There are over the counter eye drops that can treat the symptoms. It is best to use eye drops with few ingredients, saline solution is the best eye drop. Adding chemicals to the eyes can be dangerous and cause damage to sight.

Antihistamines are used to relieve the symptoms of airborne allergens. Using decongestants in combination with an antihistamine can relieve symptoms faster than using an antihistamine alone.
Antibiotics can be used in conjunctivitis if the allergies get to this point. While oral antibiotics are used to treat many conditions but eye conditions are often treated with an ointment directly in the eye.

How to take care of your eyes in daily life

By Jeffery Scott

 

Eyes are the organs why you can enjoy the wonderful world. A good 20/20 vision eye is the dream of every person. In fact, there are rarely people with excellent vision in their whole life. Some people have inborn eye diseases. Some people have deteriorated eyes with the age becoming older. Some people have more or less the near-sighted problem because of staring the computer, or television too long at a young age. So it is indispensable that everyone should learn something about how to take care his eyes in daily life to maintain good eyesight.

Diet, such as carrots, spinach, kale, broccoli and other green vegetables, is good for a healthy eye. Recently, a study shows that diet which is rich of omega-3 fatty acid can reduce the risk of age-related macular degeneration (AMD), which is the leading cause of blindness among the elderly. The omega-3 fatty acid generally exists in oily fish, sardines, salmon and some kinds of vegetables. So it is suggested that you have carrots, vegetables and foods with high omega-3 fatty acid level every day.
Drinking a lot of water is advantageous to the function of the whole body including the eyes. It is best to drink eight to ten cups of water each day. But the alcohol drinking is not recommended as the negative effects of the alcohol to the body organs.

Enough sleep is essential for both refreshed spirit and good eyesight. The time of sleeping alters according to different people. The young usually need about eight to nine hours sleeping to own a good condition. The elder may only need about four to five hours and they do not feel sleepy. It depends not to your time of sleeping but to the time which fits you best. A sleepy situation will introduce dry and sore eyes, and if the same situation lasts for a long time, your eyesight, of course, can not bear it.

Exercise is an effective way to improve your eyesight. You can do both eye focus and rotation exercise to get your muscles fully relaxed, in particular when you staring at something for an extremely long period. It is better if you can have your eyes watching a lot of green. Swimming is a recommendable sport which can have the whole body, not only eyes, relaxed. But as the sea water contains a lot of salt, so please be careful not to get your eyes sore and irritated. If your eyes are sensitive to the sea water, you can take the eye drop to alleviate the pain.

Except for those ways introduced above, regular eye test is necessary for a good vision. You can recognize how your eye is going after a year, and you may have other eye disease detected earlier. In that situation, the disease is more likely to be cured. At the same time, the doctor will give you advice about the types of eyeglass you should wear and what should be paid attention to when wearing it if you have vision problem. It is good for the eye protection.

Above all, having a good habits of lifestyle, including healthy diet, moderate exercise and regular eye test, are the keys of maintaining good eyesight. So please follow the above advices to improve your vision in your daily life.

Eye Protection Basics - How to Choose the Best Safety Eyewear

By Alicia Connolly


Why You Need To Purchase Eye Protection

The United States Federal Government has extensive legislation and a system of guidelines that has been designed to keep its citizens safe and healthy. The governing body that regulates this legislation is known as OSHA, the Occupational Safety & Health Administration. According to OSHA every year approximately $300-500 million dollars are spent in the U.S. because of eye injuries. OSHA estimates that 90% of all eye injuries can be prevented through the use of proper protective eyewear, other estimates put forth by OSHA regarding job-related eye injuries conclude that over 3 million workers' vision is at risk daily and that out of those 3 million workers over 2000 are actually injured every business day, from these 2000 job-related eye injuries 10-20% result in temporary or permanent vision loss. OSHA requires employers to provide appropriate eye protection to their workers while on the job because it is an investment worth making!

Eye Protection - What to Look For?

The American National Standards Institute also known as ANSI is the recognized entity that sets forth manufacturing safety standards within the United States. Currently, ANSI Z87.1-2003 requires safety glasses and safety goggles to provide adequate eye protection from the hazards for which they were designed, eye protection should provide a secure fit without interfering with movement or vision, they should be able to be easily cleaned and disinfected, protective safety eyewear should be reasonably comfortable, durable and have the ability to fit over or incorporate prescription safety eyewear. Z87+, an updated ANSI Standard includes new mass and high impact standards which are not yet mandated by OSHA.

When it comes to protective safety eyewear one size definitely does not fit all, it is important to know what to look for when choosing eye protection that will work with you on the job. The right fit is essential for comfort, performance and most importantly eye protection. If your safety glasses or safety goggles do not fit properly they will not protect you from risking a serious eye injury, if there are large gaps in coverage your eyes are exposed and flying debris, particles or chemicals could easily cause an eye injury. To ensure that your safety eyewear fits properly some styles of safety glasses and safety goggles offer adjustment features, or are available in multiple sizes to accommodate different facial shapes, thus providing a more customized fit for the worker. Workers are also more likely to wear comfortable fitting safety eyewear, that is stylish which increases worker compliance and decreases the risk of job-related eye injuries among workers.

If you are an employer in charge of determining what safety eyewear to choose for your employees or if you are a worker that wants the best fitting safety glasses or safety goggles for the job keep the following ideas in mind:

Frame & Fit:

Try or offer safety eyewear with multiple frame sizes so that the best protective eyewear option is chosen or available. Safety eye protection with adjustable nose pads or soft flexible fingers will easily conform to fit almost any nasal profile. Safety eyewear with adjustable temples or bendable wire core temples can provide a more secure fit and behind the ear comfort. Safety eyewear with ratcheting temples provides lens inclination to contour any cheek profile.

Filters & Shades:

Safety eyewear may be fitted with all different shades and filters to accommodate any job requirement or environment use the guide below to know how to choose the best eye protection for the job:

Filter Shades: Used to protect against ultra-violet and infrared radiation that are generated when working with molten metals, in welding, cutting, soldering and brazing.

Torch Soldering: Filter Shade 2

Torch Brazing: Filter Shade 3-4

Light Cutting up to 1": 3-4

Medium Cutting 1-6": 4-5

Heavy Cutting more than 6": 5-6

Gas Welding, Light up to 1/8": 5

Gas Welding, Medium 1/8"-1/2": 5

Safety Glass Lens Options:

Amber Lenses 85%-90%: Blocks the blue light in the visible color spectrum which creates contrast enhancement particularly in low light environments.

Clear Lenses 85%-92%: Provide excellent optics for most applications where impact protection in required, great for general purposes.

Indoor/Outdoor Lenses 50%-55% Reduce glare especially from artificial light sources.

Grey/Brown Lenses 12%-62%: Great for the outdoors, these safety glasses reduce sunlight and glare that cause eye fatigue and strain.

Blue Lenses 33%-70%: Protect from high levels of hazardous visible light, ultra-violet radiation and excessive glare in outdoor applications.

Mirror Lenses 9%-20%: Reduce glare and heat that pass through the lenses outdoors.

The standards and guidelines put forth by OSHA and ANSI are the standards that TnA Safety adheres to in our safety product catalog. TnA Safety offers a wide variety of the most popular safety eyewear brands to allow our customers to comply with federal regulations and industry standards for less.

Natural Vision Correction - How To Improve Eyesight Naturally To See Without Glasses Or Contacts

By HB Smith

Did you know that there are eye exercises you can do to improve eyesight naturally? If not, it is time you study up on the topic and get informed, especially if you ever want to be able to see without glasses. The fact is, too many people depend on their contacts and glasses, but it is possible to go without them, if you just practice a few exercises. If you do the eye exercises to improve vision correctly, you may be able to have perfect vision. It is understandable if you do not believe me because you have developed a dependency on your glasses and contacts, and that is what doctors have told you is your only option. Today, though, I am going to tell you the truth; and truth is you can improve eyesight naturally and be able to see without glasses or contacts.

Now, I am not saying that every eyesight problem can be fixed by these exercises, but most can. Whether you are nearsighted or farsighted, you can do these eye exercises to improve vision. Are you longing to know more? Read the rest of this article and your questions will be answered.

Factors That Contribute To Vision Problems

The number of individuals that need corrective eye aids has increased a lot over the last ten years. This is mainly due to the hectic lifestyles we all lead. There are many people that spend all day staring at their computer monitors and avoid doing any physical activity. Staring at a computer all day or watching TV too much can have ill effects on your sight.

Eyeglasses And Contact Lenses

The first thought, whenever eyesight begins to be a problem, is to search for something that can help. Corrective glasses and contacts are usually the easiest way to help your vision, but these are simply quick fixes. They do help alleviate headaches and blurry vision, but they make your eyes lazy. The issue with glasses and lenses is that they do not address the underlying problem, so we are not curing the vision problem, we are just finding temporary relief.

The Permanent Cure

Instead of relying on glasses and contacts, individuals can do eye exercises to improve vision and learn how to see without glasses. The eye is a muscle and if you do the right exercises, like palming, you can improve eyesight naturally. Palming can teach the eye how to relax and stop straining. To start palming exercises just do these steps:

1.) Warm up your hands

2.) Place the palms of your hands over your eyes for three minutes

3.) Repeat this process two or three times a day and make sure no light leaks in while you are covering your eyes

Dr. William Bates brought eye exercises into schools in the 1880s and found that they were very beneficial to teach people how to see without glasses. If you have an interest in doing these exercises to improve eyesight naturally, try it and see if it helps you.

There are three different levels of eye emergencies, so the action you take will depend on what level of emergency you are facing. You need to assess the emergency quickly so that your action will be prompt and effective.

1. True eye emergencies - call for immediate treatment within seconds or minutes.

2. Urgent emergencies - need some sort of diagnosis and treatment within 1 or 2 hours.

3. Semi-urgent eye emergencies - require treatment within days or weeks

Examples of True Eye Emergencies

- Chemical burns when acidic or other burning chemicals enter the eye

- Cuts when objects enter and pierce the eye

- Retinal artery occlusion which is an abrupt but painless loss of vision when the main artery to the retina is blocked

How to Treat True Eye Emergencies

If you are experiencing a true eye emergency, DO NOT:

- Apply pressure to an eye which has a foreign object in it or a cut on it

- Remove a contact lens or other object in the eye

- Touch or rub the eye

If you can't get medical attention immediately, cover the eye with a bandage, eye shield, or paper cup taped in position.

To treat chemical burns, flush the eye with water right away and repeat every 15 minutes. Don't put anything else into the eye and go to the nearest emergency room.

Do not try to treat retinal artery occlusion yourself. Go to the nearest emergency room.

Examples of Urgent Eye Emergencies

- Cellulitis - eye socket infection which causes inflammation and pain

- Corneal abrasion - scratch on the cornea caused by foreign object(s) in the eye

- Corneal ulcer - little painful sore on the cornea

- Endophthalmitis - infection in the interior of the eye which causes abrupt, extreme eye pain and impairment of vision

- Foreign object in the eye - may penetrate the eyeball

- Glaucoma - unexpected increase in pressure in the eyeball, causing reduced vision and pain

- Hyphema - bleeding into the front chamber of the eye, often due to blunt trauma

- Iritis - inflammation in the front chamber of the eye which results in redness and light sensitivity

- Lid laceration - cut on either the upper or lower eyelid or both

- Retinal detachment or tear - the retina becomes torn or detached causing flashing lights, "floaters" (spots on the eye), or shadows covering a portion of the visual field

For treatment of any of the above urgent eye emergencies, visit an urgent care center or a qualified ophthalmologist in the first few hours after noticing the eye emergency.

Examples of Semi-urgent Eye Emergencies

- Broken facial bones - eye socket bone fractures

- Exophthalmos - bulging of the eyeball which looks like staring

- Eye tumors - growths or masses that occur in or next to the eye

- Muscle imbalances - eyes are not aligned with one another

- Optic nerve tumors - growths or masses that occur in or next to the optic nerve

- Optic neuritis - swelling of the optical nerve causing rapid haziness and/or dimness of vision in either eye or both

- Orbit tumors - tumors in the cavity or socket of the skull in which the eye and its appendages are situated.

Treatment of semi-urgent eye emergencies should be sought within a few days to a few weeks (depending on the condition). Read more about eye injuries on an opthalmologist's website.
