A cataract is a clouding of all or part of the normally clear lens within the eye. It will eventually block and distort light entering the eye. More than 20.5 million Americans over age 40 are affected with this condition. Cataracts are usually found in people over age 55, but occasionally younger people can get then. Symptoms include cloudy or blurry distance vision; altered color perception; problems with glare; difficulty reading fine print; poor night vision and frequent changes in corrective lenses.
