A Natural Part of Aging: Cataracts are the leading cause of visual loss in adults 55 and over. A cataract is the clouding of the normally clear lens in your eye. This clouding may be associated with a number of symptoms: blurred vision, fuzzy night vision, glare, halos, starbursts, and difficulty driving, reading, seeing street signs, television, or following the golf or tennis ball. Prescription glasses may be changing or no longer help you see better. Colors may appear faded and less vibrant. These changes can happen over months or years. The degree can range from mild to severe and disabling. The only way to treat a cataract is to surgically remove it.
