Cataracts

A cataract is a cloudy or opaque area in the normally clear lens of the eye. Depending upon its size and location, it can interfere with normal vision.

Most cataracts develop in people over age 55, but they occasionally occur in infants and young children or as a result of trauma or medications. Usually, cataracts develop in both eyes, but one may be worse than the other.

Cataracts generally form very slowly. Signs and symptoms of a cataract may include:

• Blurred or hazy vision.

• Reduced-intensity of colors.

• Increased sensitivity to glare from lights, particularly when driving at night.

• Increased difficulty seeing at night.

• Change in the eye's refractive error, or eyeglass prescription.

Cataracts are diagnosed through a comprehensive eye exam.
