Conjunctivitis, commonly referred to as pinkeye, is a common condition affecting one or both eyes. It is characterized by inflammation of the conjunctiva, the mucous membrane covering the white of the eyes and the inner surface of the eyelids. Conjunctivitis may resolve on its own but sometimes requires treatment. It does not cause any permanent eye or vision changes.
Children get it a lot. It can be highly contagious (it spreads rapidly in schools and day cares), but it’s rarely serious. It's very unlikely to damage your vision, especially if you find it and treat it quickly.
When you take care to prevent its spread and do all the things your doctor recommends, pinkeye clears up with no long-term problems.
Conjunctivitis or Sore eyes involve redness and inflammation of the membranes (Conjunctiva) covering the whites of the eyes and the membranes in the inner part of the eyelids.
Pink eye — also called conjunctivitis — is inflammation of the thin, clear covering of the white of the eye and the inside of the eyelids (conjunctiva).
Conjunctivitis can have several causes (see below), but many eye doctors use the term "pink eye" to refer only to viral conjunctivitis, a highly contagious infection caused by a variety of viruses.
