Most styes clear up without treatment. An individual can place a warm, wet washcloth over the eye several times a day for five to 10 minutes at a time to encourage draining of the sty's pus, recommends WebMD. The eye should be kept clean and otherwise left alone.
In order to avoid spreading the infection, avoid squeezing or lancing the sty, wearing makeup, or using contact lenses, advises Mayo Clinic. An individual should seek medical attention if the sty persists longer than seven to 10 days, it becomes increasingly swollen or painful, it is accompanied by fever or chills, vision becomes impaired, or styes develop recurrently, WebMD recommends. A physician may prescribe antibiotics or make a small incision to drain the sty in particularly persistent cases.
