Q&A with Dr’s Leong & Bui
Our Eye Doctors Answer Your Eyecare Questions
What causes cataracts to form?
Dr. Leong: When a cataract forms, the lens inside the eye becomes cloudy, like a frosted window. They are NOT caused by overuse of eyes on computers or reading.
A cataract is also NOT a tumor or growth of film which cover the front of the eye. Often, cataracts develop as part of the aging process from a change in the chemical composition of the lens. Years of exposure to sunlight and other sources of UV light can contribute to cataract development.
Also cataracts can be caused by eye injuries, certain medications such as steroids, certain eye diseases and body conditions, and some birth defects. No one can predict how quickly cataracts will progress. Your eye doctor can assess cataracts and tell you if cataract surgery is required.
