A cataract is a clouding of part of your eye called the lens. Your vision becomes blurred because the cataract is like a frosted glass, interfering with your sight. It is not a layer of skin that grows over your eye, despite what you may have heard.

If your doctor or optometrist/optician has told you that you have a cataract, don’t be alarmed. Many people over 60 have some cataract and the vast majority can be treated successfully. Early cataracts may not affect your sight and do not need treatment.
