Having a cloudy lens is called a cataract. You can have a cataract in one eye or both eyes. People often get a cataract when they get older but you can get a cataract at any age. For people with cataracts, their sight might get blurry or unclear, and it might be uncomfortable to see in bright light.
Cataracts do not get better on their own. If you are worried that you or someone you know has a cataract, you must speak to your optometrist immediately. They can get worse if you don’t do anything.
