A '''cataract''' is a clouding of the lens in the [[eye]]. Cataracts are very common in older people. By age 80, more than half of all people in the United States either have a cataract or have had cataract surgery.

Common symptoms are

* Blurry vision
* Colors that seem faded
* Glare
* Not being able to see well at night
* Double vision
* Frequent prescription changes in your eye wear

Cataracts usually develop slowly. New glasses, brighter lighting, anti-glare sunglasses or magnifying lenses can help at first. Surgery is also an option. It involves removing the cloudy lens and replacing it with an artificial lens. Wearing sunglasses and a hat with a brim to block ultraviolet sunlight may help to delay cataracts.<ref>http://www.nlm.nih.gov/medlineplus/cataract.html</ref>
