A Cataract is an eye diease when the clear lens over the eye becomes cloudy, and opaque. Thus casing damaged and decreased vision. Cataracs are extremely common in elderly people, this happens due to the aging process. By the age of 80, more than half of Americans will have cataracts or have had catarct surgery. The cataract can occur in both eye's, but it can not spread from one to the other. The cataract prevents sunlight from entering the eye, limiting the amount of vision the person is able to see.
