What Are Cataracts?
A cataract is a clouding of the natural crystalline lens of the eye. Vision with cataracts can be compared to looking through a piece of waxed paper or a foggy window. Cataract development is usually a very gradual process of normal aging, but can occasionally occur rapidly. Many people are unaware that they have cataracts because the changes in their vision are so gradual.
