Health A-Z / S / Stye
A stye is an infection of one of the oil glands in your eyelid.
A stye is when a gland in your eyes becomes blocked and infected. This causes watery eyes with red swollen eyelids.
Styes are common and should clear up on their own in a week or two.
It's important to not burst the stye at home as this may spread the infection.
Treatment involves keeping your eyelids clean, treating any infection and avoiding irritants to your eye.
See your doctor if it doesn't clear up or gets worse, or if your sight become blurred.
A stye is caused when the small glands in your eyelids, which produce oils, become blocked and infected. This causes an inflammatory reaction in the lid. It usually heals on its own within a week. Sometimes you may also get blepharitis, another common condition caused by blocked glands in your eyelids.
A stye can cause:
tender swellings in your eyelids
a lump on or inside your eyelid.
The aim of treatment is to keep your eyelids clean and free of irritants, and allow the natural healing process to clear the infection. You can do this treatment at home. It involves applying a warm compress to your eyelid to unblock the glands, followed by eyelid massage and cleaning of the eyelid.
Warm compress: Hold cotton facial pads soaked in warm water against your closed eyelids for 5–10 minutes. Repeat this twice a day. This helps melt the oils in the blocked glands, allowing the oils to flow more freely.
Eyelid massage: To massage eyelids, use the tip of your finger to firmly stroke the skin of the top eyelids in a circular motion. This will help unblock the oil glands and squeeze out the oils.
Eyelid cleaning: Make up a solution of baby shampoo (1 part baby shampoo and 10 parts water). Dip a clean cotton bud in the solution and clean away any crusts present on the eyelashes and rub along the eyelids. Use a clean cotton bud for each eyelid. Repeat this process twice a day.
If you follow these steps, most styes will heal.
Avoid bursting the stye yourself at home as the infection may spread.
While your eyes are irritated and inflamed, avoid using eye make-up such as eye shadow, eyeliner and other cosmetics around the eye.
Also, avoid using contact lenses until the condition is under control.
See your doctor or optometrist if you have followed the steps for treatment and:
a stye persists or is causing distress
your eyes become increasingly red or painful
your sight becomes blurred.
You may need topical antibiotics and sterile drainage by your doctor. You will be referred to an eye specialist (ophthalmologist) for further treatment if necessary. No special tests are needed most of the time.
You should see a doctor immediately if you have any of these:
your eye doesn't get better after a few weeks.
