A cataract is a slow, progressive clouding of the eye's natural lens. It interferes with light passing through the eye to the retina. Cataracts are caused by a change in the proteins of the lens, which causes clouding or discoloration. Over time cataracts typically result in blurred or fuzzy vision and sensitivity to light or glare.
