Cataract is the gradual clouding of the normally, clear lens inside the eye. Sometime after age 40, the clear, powerful lens inside the eye loses its automatic focus.
Just like a camera lens that needs a more powerful lens to produce clear pictures, as we get older, the human lens needs extra power to provide clear vision. Often, glasses and contact lenses can provide that extra power. But when a cataract causes the lens to become cloudy, glasses or contacts won't help.
Just like the gray in our hair, vision changes from cataracts are part of the natural aging process. While aging is the most common cause of cataracts, the human lens can become cloudy at any age due to eye injuries, infections, certain medicines and diseases, like diabetes. Cataracts can even be present at birth.
Blurry vision is the most common complaint with cataracts. But other changes can interfere with sight, function and comfort.
Glare from headlights can become severely disabling when driving at night. Reading or close work gets increasingly more difficult. Colors develop a yellow tint and become difficult to tell apart. And frequent changes in glasses won't help you to see well.
When the human lens becomes so cloudy that it interferes with daily activities, surgery can be performed to remove the cataract and implant a new, clear, plastic lens that can restore good vision. Modern technology has made cataract surgery one of the safest and most successful procedures performed in America today!
