What is a cataract?
A cataract is a clouding of the natural lens inside the eye. Cataracts are the leading cause of treatable blindness in all areas of the world, especially in adults 55 and older.
Contrary to popular belief, a cataract is not a “film” over the eye. Rather it is a gradual thickening of the lens that causes the lens to become so clouded that light is either distorted or cannot reach the back of the eye (the retina) for transmission to the brain. When left untreated, cataracts will eventually cause blindness in most cases.
