Conjunctivitis – Pink Eye

Conjunctivitis (pink eye) is an irritation of the thin, normally transparent lining (called the conjunctiva) that covers the inner surface of the eyelids and the outer surface of the white of the eye (the sclera). The symptoms of conjunctivitis include redness, itchiness, irritation, and sensitivity to light.Conjunctivitis is commonly called “pink eye” because of the pale red appearance of the infected eye. Pink eye is a common and highly contagious infection among young children.

If a chemical has gotten in your eye, flush the eye with a gentle stream of cool water for at least 10 minutes.
