What are cataracts?

In a healthy eye the lens is clear or transparent. Cataracts are when the lens becomes cloudy, stopping light from reaching the back of the eye, which in turn causes blurred or reduced vision.

Over time cataracts can become worse and your vision gradually gets cloudier. A simple procedure can be carried out to remove the cloudy lens and replace it with an artificial one, this normally allows you to regain good vision once again.
