What to do about cataract

After treatment, you may see better than you have in decades.

Have you noticed that colors aren't as bright as they used to be? That there is more glare at night? That your distance vision is hazy, even with new glasses?

By the time you turn 65, chances are about 50-50 that you will have begun to develop a cataract, a clouding of the clear lens that focuses light onto your retina (the light-sensitive tissue at the back of the eye that sends the image to your brain via the optic nerve). The lens is composed of water and proteins arranged to let light through with minimal distortion. With age, the proteins can clump together, letting less light through and blurring vision. You may also be at increased risk for cataract if you regularly take corticosteroids or the anti-cancer drug tamoxifen. (For other risk factors, see "Can cataract be prevented?")
