Cataracts (clouding of the eye’s natural lens)

Cataracts are the most common cause of vision loss in people over age 40 and the principal cause of blindness in the world. A cataract starts out small and at first has little effect on your vision. You may notice that your vision is blurred a little, like looking through a cloudy piece of glass or viewing an impressionist painting.

A cataract may make light from the sun or a lamp, seem too bright or glaring. Or you may notice when you drive at night that the oncoming headlights cause more glare than before. Colors may not appear as bright as they once did. The type of cataract you have will affect exactly which symptoms you experience and how soon they will occur.

When symptoms begin to appear, new glasses may improve your vision for a while, Strong bifocals, magnification, appropriate lighting or other visual aids are used as well. Surgery is a recommended option if your cataracts are seriously impairing your vision and your daily life. Cataract surgery is a simple, relatively painless procedure.
