What Are Cataracts?

A cataract is any cloudiness or opacity of the natural lens of the eye due to natural protein build-up that prevents the light rays from passing through the lens normally. A cataract causes light to be scattered inside the eye. This results in symptoms of glare and blurred vision. Cataracts generally progress very slowly over time resulting in gradual loss of vision. There are different types of cataracts, but the most common form that typically occurs in older people is a yellowish-brown discoloration of the lens that causes a change in color perception as well as blurred vision.

Cataract Diagnosis

A complete eye exam will determine whether you have a cataract and to what extent it is impacting your vision. Your examination will include a vision test, called a refraction, to see if your vision may be improved with glasses. You may also have your vision tested with an instrument that shines light in your eye to see how much of your vision is affected by glare. Your doctor will utilize an instrument called a slit lamp that functions like a microscope as he examines the lens of your eye. This allows your doctor to assess the extent of cataract formation. Your doctor will also examine all of the other parts of the eye, looking for any other problems that may affect your vision.
