Cataracts are a cloudiness that forms in the lens of the eye, causing poor vision as the cloudiness interferes with light entering the eye. Most cataracts are age related, which means the chances of developing them later in life are higher. If left untreated cataracts can cause blindness. People with cataracts may experience difficulty reading, recognising faces and watching television.
For many people early cataracts won’t require surgery. If they begin to interfere with everyday activities, the cataract affected lens can be surgically removed and replaced with a clear artificial lens.
