A stye, also known as a hordeolum, is a painful lump that forms beneath the eyelid or at the base of the eyelashes.
Acute inflammation of the eyelids is present, along with gritty, itchy, and watery eyes. The oil glands (sebaceous glands) in the eyelids become clogged, resulting in a stye. The upper or lower eyelid can develop styes. Stye development can also be triggered by bacterial infections.
The pus in styes is usually yellowish. The vision is unaffected in any situation of stye. Styes, on the other hand, if left untreated, might worsen and develop to chalazion. Multiple styes may appear at the same time, depending on the severity of the infection. In most cases, styes are not contagious. Styes caused by bacterial diseases, on the other hand, are communicable.
