Causes of Blurred Vision - What Are the Main Causes of Blurred Vision?
Life can be more difficult if you are experiencing blurry vision. It would be more frustrating to know that it can be a sign of many illnesses or serious health problems. Quality of vision depends not only on a transparency and clarity of crystalline lens, but conductivity and normal functioning of an optic nerve and structure of retina. The major causes of blurred vision actually are the weakening or eye muscles. It is very important to keep eye muscles in perfect condition because movement of eyeballs, adjustment of the curvature of the lens and many functions of the eyes depend on them.
Some of the common causes of blurred vision is cataract. The sign of this problem is the noticeable blurring and worsening of eyesight such as night vision, fading of colors. People with cataracts have difficulty in driving at night because the glaring headlights of the passing vehicles can dazzle the eyesight.
Another eye problem that can deteriorate vision is macular degeneration. People will suffer from macular degeneration if the neurons which are located at the back of the eyes cannot detect the light. Because the neurons are defected, the blurring image cannot be corrected by eye glasses or contact lenses. Many researchers and eye care practitioners suggest that certain nutrients which have high level of antioxidants such as zinc, lutein, zeaxanthin and vitamins A, C and E will halt or slow the development of macular degeneration.
Eyesight disorder may also be caused by nearsightedness, or myopia as it is medically termed. Nearsightedness is a condition in which close objects are seen clearly, but far away objects that are seen blurred because the eyeball is too long or the cornea is too curved. As a result, light focuses in front of the retina so you see a blurred image. Myopia is a common disorder and it has been reported that more than 25 % of American adults suffer from this eye disorder.
One of the causes of blurred vision is farsightedness or hyperopia. In the opposite of myopia, farsightedness occurs if vision is better for distant objects than for near objects because the eyeball is too short or the cornea has too little curvature, so the light which enter the eye is not focused correctly.
When you are experiencing dry eyes sometimes images can appear fuzzy. Your eye needs constant flow of tears to provide constant moisture and lubrication to maintain vision and comfort. When there is an imbalance in this tear system you may experience dry eyes. Dry eyes may be due to low humidity, low blink rate or windy conditions. Complications are uncommon but go to see a doctor if vision becomes affected (more than slight temporary blurring).
