Cataracts

What Is a Cataract?

A cataract is a clouding of the natural lens of the eye. The most common factor in cataract formation is increasing age, but there are additional factors, including smoking, diabetes, and some medications, such as steroids. Cataracts can also be present at birth or be caused by injury to the eye.

More than 20 million Americans over the age of forty have cataracts, and it is the most frequent cause of preventable blindness in the world.

Cataract Treatment

The existence of a cataract does not necessarily mean you need surgery. A cataract needs to be removed only when vision loss interferes with your everyday activities, such as driving at night, reading, or watching TV. The decision to have cataract surgery is one that you and your doctor should make together.

Cataract Symptoms

While a comprehensive eye examination by an eye care practitioner can determine for certain if you have a cataract forming, there are a number of signs and symptoms that may indicate a cataract:
  • Inability to read small print
  • An increase sensitivity to glare, especially at night when driving
  • Blurred or hazy vision where colors may seem yellowed
  • A tendency to become more nearsighted
  • The feeling of having a film over the eyes
