What are cataracts?

Cataracts are the clouding of the eye’s natural lens.  The lens normally focuses images on the retina.  When the clouding occurs in the lens, blurred vision is the result.  Some people describe their vision as if they are looking through waxed paper or a waterfall.  In fact, the word cataract in Greek means “waterfall.”  Other symptoms include glare and halos around lights, starburst with oncoming headlights, or the inability to distinguish images at near or distance with normal lighting.
