This lady gets chastised by the scary liver man for partying too hard!
A cataract is a clouding of the normally clear lens of the eye. Cataracts are incredibly common; they are the most common cause of impaired vision or blindness. By age 80 more than half of all Americans have a cataract in one or both eyes, or they have had cataract surgery before then. Diabetics are most prone to developing cataracts, and as the incidence of diabetes is growing worldwide, so too are cataracts.
Some people believe cataracts are an inevitable part of aging but I disagree and believe there is plenty you can do to protect your vision.
