Definition Most bumps on the eyelid are styes. A stye is an inflamed oil gland on the edge of your eyelid, where the lash meets the lid. It appears as a red, swollen bump that looks like a pimple. It is tender, especially to the touch. Alternative Names Bump on the eyelid; Stye; Hordeolum Causes, incidence, and risk factors A stye is caused by bacteria from the skin that get into the oil glands in the eyelids that provide lubrication to the tear film.
