How Contagious Are Styes?

Quick answer: Styes are not contagious in normal day-to-day contact, you can't "catch" one just by being near someone. But because a stye is a bacterial infection, there's a small chance the bacteria can spread through shared pillowcases, towels, or unwashed hands, so basic hygiene matters.

What is a stye?

A stye is a small, red, often painful lump at the edge of the eyelid, caused when an oil gland becomes blocked and infected. Like a pimple, it's sore until it drains. Most styes clear on their own within a couple of weeks. To help it along:

• Use a warm compress: a clean cloth soaked in warm (not hot) water, held over the eye for 10 to 15 minutes, three to five times a day.
• Keep the area clean: gently cleanse with eye wipes or a mild diluted baby-shampoo solution, wiping once away from the eye, without rubbing.
• Don't touch it, skip eye makeup, and never squeeze or pop it.

Can a stye spread to others?

In everyday situations, no, there's no need to stay away from others. Because the infection is bacterial, the only real risk is indirect: discharge left on a pillowcase or towel that someone else uses. Wash affected bed linen, don't share pillows or towels, and wash your hands well after touching the eye.

When to see an eye doctor

Most styes resolve at home, but see an eye doctor if a stye isn't improving within 48 hours, keeps coming back, or you have several at once. A persistent lump may instead be a chalazion, which is usually less painful. If the area becomes very swollen or painful or your vision is affected, treat it as urgent, see our emergency eye care. Recurrent styes can also be linked to blepharitis. See also reasons for eyelid pain.

How a stubborn stye is treated

If warm compresses and cleaning aren't enough, your eye doctor can offer antibiotics (drops or oral), a steroid injection to reduce swelling, or a quick drainage under local anesthesia.
