Conjunctivitis

Conjunctivitis (also called pink eye, or sticky eye) is an inflammation of the outer layer of your eye, which is called the conjunctiva. The conjunctiva is a thin, clear tissue that covers the white of your eye (called the sclera) and the inside of your eyelid.

If your conjunctiva is inflamed, the small blood vessels inside it widen, making your eye look red or pink. However, other things can also cause red or pink eyes, so if you're not sure what's causing yours, see your GP, optometrist, or ophthalmologist (eye doctor).
