Sight is a precious gift which can be snatched away by a variety of assaults if you are age 50 or older.

The risk of developing one of four disorders: cataract, glaucoma, age-related macular degeneration, and diabetic retinopathy, poses a real threat for adults which increases with age, the main risk factor for these diseases.

For example, half of all people between the ages of 65 and 74 have cataracts; after age 75, about 70 percent do. Glaucoma is most common in people over 60. Regarding vision, as you grow older, you have to grow wiser too. That means knowing the steps you can take to prevent these vision problems. You also need to know the warning signs of vision problems, how they are diagnosed, and the best treatment options.

The Aging Eye, published by Harvard Medical School for adults over 50, can help you determine your risk of developing these disorders. It describes the symptoms with an update on advances in diagnostic testing. It also reports on advances in surgery and breakthroughs in the development of disease-arresting medications.
