How to Fix a Lazy Eye - Lazy Eye Correction Techniques

Vision disorders are a major public health issue and concern in the U.S affecting about 2.9 million people nationwide. An example of a specific vision concern impacting much of the American population under 40 years old is called Amblyopia, better known as Lazy eye. There is a reason to be optimistic about the treatment of this vision condition because there are techniques and exercises specifically designed to provide a remedy for this vision problem. This is accomplished by strengthening the eye muscles in terms of their connection and communication with the brain. Before performing any vision exercise routine, consult your optometrist to be guided in the correct protocol of exercise techniques. Here are some solutions that show you how to fix a lazy eye.

Basically, the concept of the treatment of this vision disorder is related to the use of an eye patch. This patch is worn on the normal eye that is stronger than the weaker one. This is to ensure that the stronger eye does not overcompensate for the function of the lazy eye. Here are a series of techniques that show you how to correct a lazy eye:

All of these techniques are performed while wearing the eye patch.

Eye Rolls: Roll your weaker eye in a circular motion as this helps to strengthen the eye muscles.

Focusing: Focus the weaker eye on an object in front of it. For example, you can use a pen or a pencil. Maintain your focus on the pen or pencil as you move it back and forth. This particular technique strengthens the eye muscles and improves communication between the eyes and the brain.

Tracking: with this technique you can use an object such as a pen or pencil once again and using your weaker eye, keep track of the pen or pencil as you move it up and down, from left to right, diagonally and then back and forth. This technique strengthens the eye muscles; reinforcing the connection between the brain and the eyes.

Reading fine print: An activity such as reading fine print actually challenges your weaker eye to work better. Some examples are crossword puzzles, books and other word games. Perform these activities for about an hour while the stronger eye is inactive under the guidance of your vision care specialist.

Under the proper supervision of an optometrist, an eye patch worn over your stronger eye stimulates the function of the lazy eye causing it to work harder. Techniques such as eye rolls, focusing and tracking and fine print reading are lazy eye exercise remedies. These techniques show you how to remedy this vision disorder through a series of exercises that not only strengthen the eye muscles but, they rebuild the foundation necessary for the weaker eye to connect with and communicate with the brain. Ultimately, such techniques can correct this vision condition.

How to Know If You Qualify for Lasik Surgery

By   |     
  
Lasik (laser assisted in situ keratomileusis) surgery is a procedure that can help many individuals who have nearsightedness, farsightedness or astigmatism regain back their lost vision. Before the surgery can take place, potential candidates need to undergo various tests to determine lasik surgery compatibility. These tests are not only painless but necessary as approximately 30% of people are not good candidates for lasik surgery.

Individuals who are scheduled for lasik surgery compatibility tests are asked to refrain from wearing their soft contacts for 48 hours or their hard contacts for one week before testing as contacts can alter the shape of the cornea, possibly affecting test results. The testing also involves dilating the pupils, so patients should arrange for transportation following the examination.

Tomography of the cornea
Tomography of the cornea, also known as optical coherence tomography (OCT), allows the ophthalmologist to thoroughly evaluate the anatomy of the cornea. The term "tomography" refers to the ability of the test to provide the clinician with sectional images of the cornea. This test is completely noninvasive, which means no contact is made with the eye. Instead, images of the cornea are produced using reflected light (near infrared light) from the eye's tissues.

Within just a few seconds, the ophthalmologist can get accurate three-dimensional images of the cornea that help determine whether the patient is a candidate for lasik surgery. Among the measurements taken is the coefficient of variation, which can reveal how much cell loss has occurred in the cornea. This information is critical for surgeons from which to base their decision.

Visual acuity and refraction examination
These quick tests are common during an optometry examination. A visual acuity test involves reading letters on a chart (Snellen chart) that is 20 feet away while covering one eye first before the other.

The refraction examination goes hand in hand with the visual acuity test. Also known as a vision test, the refraction test tells the doctor what prescription individuals need to achieve 20/20 vision. To conduct the test, individuals sit in a chair 20 feet away from the Snellen chart and look through a device that contains various lenses. The doctor changes the lenses and asks patients which ones allow them to see the letters most clearly.

Ophthalmology examination
The ophthalmology exam involves several quick tests. One is dilation of the pupils, which allows the ophthalmologist to evaluate the health of the retina and the optic nerve. Another is a measure of the intraocular pressure of the eyes. This test, known as tonometry, can be done in several different ways.

The most common way is for patients to stare through an examination device while the doctor applies a rapid puff of air to the eye. The machine can determine eye pressure by measuring the light reflections off the eye.

Some doctors use a slit lamp. In this test, eye drops are administered to numb the eyes and a strip of paper containing dye is gently tapped on the cornea. Patients are then told to look through a device called a slit lamp. The doctor adjusts the tip of the tonometer until it barely touches the cornea to get a reading. Another test is done to check whether patients have an adequate amount of tears. After numbing the eyes, a tiny strip of paper is placed inside the lower eyelids.

After several minutes, the doctor removes the paper to determine how much moisture the eyes can produce. The results of these tests, plus additional information about a patient's overall health, are all taken into consideration when determining whether an individual is a candidate for lasik surgery.
