Eyes are one of the most overworked organs. We depend on our eyesight daily and often don't realize how much until something goes wrong. Vision impairments can be the result of heredity or trauma to the eye. Routine eye exams can detect and help prevent further loss of vision. The most common of vision impairments can easily be corrected with eyeglasses, contact lenses and now surgery. Through research, scientists are discovering new ways to improve and restore vision.
