There are four different types of cataracts. Name these four types and describe

Age-related cataract: Most cataracts are related to aging. More than half of all Americans age 65 and older have a cataract.

Congenital cataract: Some babies are born with cataracts or develop them in childhood, often in both eyes. These cataracts may not affect vision. If they do, they may need to be removed.

Secondary cataract: Cataracts are more likely to develop in people who have certain other health problems, such as diabetes. Also, cataracts are sometimes linked to steroid use.

Traumatic cataract: Cataracts can develop soon after an eye injury or years later. Although researchers are learning more about cataracts, no one knows for sure what causes them. Scientists think there may be several causes, including smoking, diabetes, and excessive exposure to sunlight.
