Pink eye, or conjunctivitis, is an inflammation or infection of the conjunctiva, the thin, transparent membrane that lines the eyelid and covers the white part of the eye (sclera). It is characterized by redness and swelling of the conjunctiva and can be caused by infections, allergies, or irritants. Pink eye is highly contagious, especially when caused by infections, and can affect one or both eyes.
