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.[Citation Needed]
Common symptoms are
- Blurry vision
- Colors that seem faded
- 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.
