Explained: Cataracts

A cataract is clouding or opacity of the lens in your eye.

Cataracts usually form slowly and cause a gradual blurring of vision.

When a cataract develops, the lens becomes cloudy and can stop the light rays passing through to the retina and this causes vision to be blurred.

Effects of Cataracts:

• Sensitivity to glare
• Double vision
• Gradual loss of vision

Often cataracts are diagnosed at routine eye appointments. Cataracts often cause glare and difficulty with night-time driving.

In most cases, cataracts are successfully treatable by surgery. The damaged lens is removed and an artificial lens is inserted.
