Tearing, or having too many tears, can come from being sensitive to light, wind, or temperature changes. Tearing may also mean that you have a more serious problem, such as an eye infection or a blocked tear duct. Your eye doctor can treat or correct both of these conditions. 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.
