A cataract is a clouding of the lens in the eye. This is a natural part of aging and if you are over 55, there is a good chance you may have some form of cataract. When the lens becomes clouded by a cataract, it prevents light and images from reaching and focusing on the retina, the light sensing nerve tissue that lines the back of the eye. Vision with cataracts can be described as seeing life through a cloudy window- objects become blurred, colors become dull and seeing at night becomes more difficult.
Cataracts are the leading cause of visual impairment in the United States. However, because cataracts grow slowly over a long period of time, many people suffer from this condition without realizing it.
