What is Conjunctivitis?
Conjunctivitis, commonly known as pink eye, is an inflammation or infection of the conjunctiva. The conjunctiva is the transparent membrane that lines your eyelid and covers the white part of your eyeball. When small blood vessels in the conjunctiva become inflamed, they’re more visible. This is what causes the whites of your eyes to appear reddish or pink.
