"Pink eye" is a term commonly used to describe red eye and refers to both viral and bacterial infections of the conjunctiva (conjunctivitis). It can also have other causes, such as allergy.

Pink eye caused by a virus may involve clear discharge or some amount of pus and mucous discharge.

Pink eye caused by bacteria is more common in children than adults and may involve a more continuous and thicker discharge of pus and mucus.
