MedicineNet Pink eye is a familiar name for conjunctivitis, or the inflammation of the conjunctiva (the membrane covering the eyes and lining the eyelids). It is a common viral or bacterial infection, affecting 3–6 million people in the US alone each year. The name stems from the way the condition makes the eye look pink or red along with other symptoms of itchiness, watering, and swelling. While pink eye typically cures itself, antibiotics are sometimes necessary. It is often contagious, except when caused by allergens, passed directly from a person or from contaminated objects. One common myth, popularized by the 2007 Seth Rogen comedy Knocked Up, claims that pink eye is spread from fecal bacteria left on pillows from flatulence. Related myths include that the infection results from eye contact with the anus or semen during sex. The infection, rather, is principally caused by rubbing the eyes with hands carrying a certain virus or bacteria.
