A cataract is a clouding, opacity, yellowing, or accumulation of fluid in the lens of the eye that results in a loss of vision and interferes with your lifestyle. Most cataracts are related to aging, and by the time you reach the age of 70 most people will show some signs of cataracts. Age related cataract may occur in one eye first but with time will usually be present in both. The lens is a clear part of the eye that helps to focus light, or an image, on the tissue lining the back of the eye called the retina. The retina  is lined with the receptor cells that transform light particles into electrical impulses. A healthy lens is transparent due to the special proteins that help the layers repeat in a regular pattern that causes the least interference and passes the most light through.

When your eyes, mind, and body are relaxed, you will naturally see better. By periodically relaxing your eyes throughout the day, you reduce the strain and stress you place on them.

One of the pioneers of natural remedy to improve vision using eye exercises is Dr. William Bates (1860 - 1931). He had attributed majority of eyesight problems to the strains placed on eyes. While his methods for improving eyesight are controversial in the scientific community, there seems to be plenty of anecdotal evidence of positive results of eyesight improvement through eye exercises.

First and foremost, keep in mind that vision insurance benefits are a supplement to health insurance. If you do not have an occupation or affiliation that will allow you to acquire insurance, you may want to consider purchasing insurance on your own to take care of your medical needs. Yet the selection aspect can be puzzling to some since there are different kinds of vision insurance available.

Smoking is the best thing you can do if you want to develop cataracts at a young age. Smoking also is associated with the other leading causes of blindness, glaucoma and central retinal degeneration. Reducing your UV sun exposure by wearing quality sun glasses that meet A.N.S.I. standards is helpful. Sun wear that wraps and blocks sun exposure from the side is even more helpful. Although research studies have given mixed results, time will probably bear out a protective effect of antioxidants on the lens tissue. Supplementation with vitamin C, vitamin E, and special plant pigments  likely will be shown to reduce cataract development. Eating foods that are complex carbohydrates such as whole grains and less refined foods with a lower tendency to cause sharp rises and falls in blood sugar are associated with a decreased risk of cataract formation. Leafy green leafy vegetables, fruit, and other foods with antioxidants are always the best source of supplements.

Annual comprehensive dilated eye health exams are vital to monitor for cataracts and allow your optometrist to check for signs of retina degeneration, glaucoma, and other eye diseases. Early treatment and detection of eye disease may save your sight and life! The most common symptoms of a cataract are cloudy or blurry vision and problems driving at night due to halos and glare. Frequently, after years of minor changes, patients developing cataracts will start to have rapid changes in their eye glass prescription as they become more nearsighted from the changes in the lens.
