Eye Care Basics

Cataracts

Causes
Cataracts occur when the natural lens inside the eye becomes discolored or cloudy, causing blurred or distorted vision. This blurring is the result of a chemical change within the eye, most often occurring after the age of 55. The direct cause of cataracts is not known, although heredity, injury, and/or disease might be factors. Additional factors that may contribute to the development of cataracts include exposure to ultraviolet light, smoking, and certain prescription drugs.

Symptoms
Indications that cataracts may be forming include:

blurred/hazy vision
spots in front of the eyes
increased sensitivity to light and resulting glare
feeling of "film" over the eyes
a temporary improvement in near vision
decreased vision in low illumination (night driving)

Diagnosis and Treatment
Although there is currently no known method to keep cataracts from developing, your eye care specialist can diagnose and monitor cataracts, and also prescribe glasses or lenses that may improve vision. Ultimately, most cataracts should be surgically removed.
