What is keratitis?

ANSWER

Keratitis is painful inflammation of your cornea -- the clear covering over the pupil and colored part of your eye. Doctors sometimes use the term "corneal ulcer" to describe this condition, which is usually caused by an injury or infection.

See your doctor right away if you have a problem with your eyes. Keratitis can become serious quickly.
