What is a cataract in the eye?

A cataract is when the lens becomes cloudy instead of clear.

Cataracts affect the lens of the eye.

They make vision blurred or misty because light cannot pass through the lens well.

Less light can pass through the cloudy lens, so the retina gets too little light.

A healthy lens is clear and focuses light onto the retina to make a sharp image.

Surgery is used to remove the cloudy lens and replace it with a clear artificial lens.

The clear artificial lens lets light through and focuses it on the retina, so the image is sharp again.

Cataracts are most common in older people, but can sometimes occur in babies or younger people.

No. Glasses may help a little, but only surgery to remove the cloudy lens can cure a cataract.

It is a quick, routine operation and most patients get much clearer vision afterwards.
