What is a Cataract? |
|
A cataract is a clouding of the eye’s
naturally clear lens. The lens focuses
light rays on the retina-the layer of
light-sensing cells lining the back of
the eye-to produce a sharp image of what
we see. When the lens becomes cloudy,
light rays cannot pass through it easily
and vision is blurred. |

|
What are the symptoms of cataract? |
|
The amount and pattern of cloudiness
within the lens can vary. It the
cloudiness is not near the center of the
lens. You may not be aware that a
cataract is present. |
