Conjunctivitis, more commonly referred to as “pink eye,” is an inflammation or infection of the transparent membrane (conjunctiva) that lines the eyelid and part of the eyeball.
When inflamed, small blood vessels in the conjunctiva become more prominent, which is what causes the pink or red look of the whites of the eyes. Conjunctivitis can spread quickly from one person to another and affects millions of Americans at any given time.
