Cataracts keep light from easily passing through the lens, and this causes loss of eyesight. Signs of cataract include having cloudy vision, problems driving at night because of headlight glare, or problems with glare from lamps or the sun, and double vision. Cataracts often form slowly and cause no pain, redness, or tearing in the eye. Some stay small and don't change eyesight very much. If a cataract becomes large or thick, it usually can be removed by surgery.
Most people have plenty of time to decide about cataract surgery.
Talk to your doctor about your options. Cataract surgery is very safe. Most people do not need to stay overnight in a hospital after surgery. It usually takes a few months for the eye to heal after cataract surgery. Glaucoma results from too much fluid pressure inside the eye.
