There is a greater risk of you developing cataracts if you have diabetes, smoke, drink alcohol, or have prolonged exposure to sunlight. Some people get a Secondary cataract after surgery for glaucoma, or are using some sort of steroid. A Traumatic cataract can show up years later from an eye injury. A Congenital cataract is something that people can be born with or develop in childhood usually in both eyes. They can be so small that they do not affect the vision. Radiation cataracts can develop after exposure to radiation. More than half of all Americans either have a cataract or have had cataract surgery by the time they are 80 years old.
