What are Cataracts?


A cataract is a clouding of the lens in your eye. This can cause blurred vision, a brown or yellow tinge to your sight and spots where your sight is less clear.

Cataracts are a common eye condition and are a natural part of ageing. They are easily treated.

Cataracts are caused by a change in the cell arrangement and water content of the lens in your eye, causing it to become misty. As the cataract grows larger it will cloud more of your lens, making your vision more blurred.
