What is a cataract?
A cataract is the clouding of the lens in the eye and is one of the most common eye diseases. In fact, everyone will develop cataracts if they live long enough.
The lens is a structure that sits behind the iris, the coloured part of the eye. The lens is critical for your vision, because when light shines through your pupil, it must pass through your lens to reach the retina at the back of your eye. The retina is sensitive to light patterns and transmits signals to your brain, which interprets what you see. This is why the lens must remain clear for optimal vision.
