A sty is a bacterial infection of the glands near the root of an eyelash. It is a very common infection that is rarely serious, although it is typically painful.

What Causes Styes?

Styes are commonly caused by bacteria.

Symptoms of Styes

Typically, the first thing you will notice is a lump that resembles a pimple near the root of your eyelash. After that, the lump may grow, becoming more painful and swollen over the course of several days. Eventually, the lump will burst, and drain.

Treatment for Styes

Styes require no treatment, but may heal faster if you apply a warm compress for 10 minutes, four times a day. Usually, it takes about a week from the time they emerge to the time they fully heal.

You can prevent styes by doing your best not to rub your eyes, and keeping your eyelids clean. If your styes are a concern or have been occurring more frequently, it is important to keep your eyelids clean and talk to your eye care professional.
