What is a cataract?

The lens is made mostly of water and protein. The protein is arranged to let light pass through and focus on the retina. Sometimes some of the protein clumps together and starts to cloud a small area of the lens. This is a cataract. Over time, the cataract may grow larger and cloud more of the lens, making it hard to see.

Although researchers are learning more about cataracts, no one knows for sure what causes them. Scientists think there may be several causes, including smoking and diabetes. Or, it may be that the protein in the lens just changes as it ages. Scientists do know that a cataract won’t spread from one eye to the other, although many people develop cataracts in both eyes.

Cataract Vision

A cataract is a cloudy area in the eye’s lens that can cause vision problems. The most common type is related to ageing. More than half of all the people age 65 and older have a cataract. In the early stages, stronger lighting may lessen the vision problems caused by cataracts. At a certain point, however, surgery may be needed to improve vision. Today, cataract surgery is safe and very effective.
