What is a Cataract?
|
|
A cataract is a yellowing or clouding of the
lens of the eye. The lens of the eye works much like the
lens in a camera to keep things in focus. Cataracts can
block or scatter light, causing blurred vision, dim or faded
vision, ghost images, or starbursts and halos around lights.
The most common cause of cataracts is aging. People with
cataracts often report that driving is more difficult,
at night. |

You may start having trouble seeing street signs until you are right
on top of them. It may become difficult to see TV or to read,
in dim light – and even your best glasses may not be
helping.
Yellowing and clouding of the lens of the eye is a normal part of
the aging process. Cataracts can also develop as a result of injury,
as a side effect of certain medications, as a complication of
diabetes, and as a result of previous eye surgery. Rarely, cataracts
can be present at birth or develop in early childhood. Since
cataracts usually develop painlessly, over many years, most people
do not notice them, at first. Sometimes, when vision changes from
early cataracts do become noticeable, a change in glasses can help.
When glasses don’t help, and when the decrease in vision from
cataracts begins to affect your lifestyle, it may be time to
consider
cataract surgery. |
