After you see your doctor, she may name the infection you have. You may hear her use medical terms like:
Pinkeye (conjunctivitis). It's an infection of your conjunctiva and usually gives your eyes a pink tint. It can be caused by a bacteria or virus, although sometimes you might get it from an allergic reaction or irritants. It's common to get pinkeye when you have a cold.
Keratitis. This is an infection of your cornea. It can be caused by bacteria, viruses, or parasites in water. It's a common problem for people who wear contact lenses.
