What is Cataract?

A cataract is a condition affecting the lens of the eye, which causes the normally clear lens to become cloudy. This restricts the amount of light that is able to enter the eye, resulting in blurred vision, dazzle and glare, and sometimes also double vision. The lens is inside the eye, behind the pupil and iris, as shown in the diagram.

  

              

The cause of cataracts is most commonly related to old age, but they can occur at any age and for many reasons. This might be because of certain medications, such as steroids, or if you have a condition such as diabetes. Previous trauma to the eye also can lead to rapidly developing cataracts. 

 

 Cataracts usually develop gradually and can often go unnoticed at first.
