CATARACT
Cataract is a clouding of the lens in the eye which keeps light and images from reaching the retina. It can be the reason that sharp image become blurred or seeing things at night is more difficult. It may be why eyeglasses or contact lenses that used to help you read, or do other simple tasks, no longer seem to help.
Cataract is the leading cause of visual loss in adults age 55 and older. By age 75, almost everyone has a cataract. In addition to aging, other causes of cataracts include: medical problems, such as diabetes, injury to the eye, medication such as steroids, long term unprotected exposure to sunlight. However, cataracts are highly treatable, and through advances in both cataract surgery and intraocular lenses, more people are experiencing full restoration of their vision than ever
