Cataracts are a normal part of the aging process. About half of Americans aged 65 to 75 have cataracts and about 70% of those 75 and over can expect to have this condition.
A cataract is a cloudy area in the lens of the eye. A normal lens is clear and lets light pass to the back of the eye or retina. A cataract blocks some of the light, and as it develops, makes it harder for a person to see.
Most people with cataracts have a cataract in both eyes. However, one eye may be worse since each cataract can develop at a different rate. Some people with cataracts don’t even know it. Their cataract may be small, or the changes in their vision may not bother them very much. Other people who have cataracts cannot see well enough to do the things they need or want to do.
Some Symptoms of Cataracts
- Cloudy, fuzzy, foggy, or filmy vision
- Changes in the way you see colors
- Problems driving at night – headlights seem too bright
- Problems with glare from lamps or the sun
- Frequent changes in your eyeglass prescription
- Double vision
How is a Cataract Diagnosed?
A simple eye exam is all that is needed to find a cataract. Just because you have a cataract does not mean it must be removed immediately. Cataract surgery can almost always be put off until you are unhappy with the way you see.
