Summary
A sore red bump on the eyelid looks alarming, yet most styes settle with warmth, clean hands and a little patience while the body does the rest.
Most styes clear up on their own, usually within a week or two. You can help the process with a clean, warm compress held against the closed eye a few times a day, gentle cleaning of the eyelid edge and a short break from eye make-up and contact lenses. The one thing not to do is squeeze it. A stye that spreads, affects your sight or keeps coming back deserves a look from a pharmacist, optometrist or GP.
What a stye is
A stye, sometimes spelled sty and known medically as a hordeolum, is a small, tender lump on the eyelid. It forms when one of the tiny glands or eyelash follicles along the lid becomes blocked and infected, most often with bacteria that normally live harmlessly on the skin. The lump may develop a yellowish head, much like a spot, and the whole lid can look puffy and red. Styes are common at any age and are not usually a sign of anything serious.
Stye or chalazion?
A chalazion is a related lump caused by a blocked oil gland deeper in the lid. The two are easy to confuse, and one can sometimes follow the other.
| Stye | Chalazion | |
|---|---|---|
| Feel | Sore and tender | Often painless or only mildly uncomfortable |
| Position | Usually right at the lash line | Usually a little further back from the edge |
| Cause | Infection of a gland or follicle | Blocked gland without active infection |
| Course | Typically settles in a week or two | Can linger for weeks before shrinking |
Warm compresses are helpful for both. A chalazion that stays large or presses on the eye can be drained by an eye specialist.
What makes a stye more likely
- Rubbing or touching the eyes with unwashed hands
- Old or shared eye make-up, or sleeping without removing it
- Contact lenses that are not cleaned or replaced as instructed
- Blepharitis, an ongoing inflammation of the eyelid edges
- Skin conditions such as rosacea, and having had styes before
Using a warm compress
Warmth softens the blocked material so it can drain on its own. Many health services suggest holding a warm compress to the eye for five to ten minutes, three or four times a day.
- Wash your hands with soap and water.
- Soak a clean flannel or cotton pad in water that feels comfortably warm against the inside of your wrist, not hot.
- Wring it out and hold it gently against the closed eyelid.
- Re-warm it once or twice if it cools during the session.
- Use a fresh cloth each time and keep it separate from other people's towels.
After the compress, you can wipe along the lash line with a clean cotton pad dampened with warm water. Some people use a small amount of baby shampoo diluted in warm water, taking care not to get it in the eye itself.
What to avoid while it heals
- Squeezing or popping it. This can push the infection deeper into the lid and make things worse.
- Eye make-up. Skip it until the stye has gone, and replace any products used in the days just before it appeared.
- Contact lenses. Wear glasses for a while instead; our guide to cleaning glasses without scratching the lenses helps keep them clear in the meantime.
- Rubbing. Tired, itchy eyes invite rubbing, which spreads bacteria. If screens leave your eyes sore, our tips on reducing eye strain from screens may help.
Do you need drops or antibiotics?
For a simple stye, usually not. A pharmacist is a good first stop: they can look at the eyelid, confirm what it is and tell you whether anything from the counter is worth trying. Antibiotic creams or tablets are generally kept for infections that spread beyond the stye or do not settle, and a doctor or prescribing professional will decide whether they are needed.
Signs it needs a professional
Arrange to see a GP or optometrist if:
- The lump has not improved after a couple of weeks of home care
- It keeps growing, or the whole lid becomes very swollen
- It is affecting your vision or pressing on the eye
- You get styes again and again
Get urgent same-day advice if redness and swelling spread around the eye or onto the cheek, the eye itself becomes painful or red, your sight changes, or you feel feverish and unwell. These can signal a spreading infection that needs prompt treatment.
Lowering the chance of another one
Clean hands before touching the eyes, careful contact lens routines and fully removing make-up at night make a real difference. People prone to blepharitis often benefit from a short daily lid-cleaning routine even when no stye is present. If styes keep returning, mention it at your next routine eye exam, where the eyelids can be checked under magnification.

Changes that cost a minute or less
Easy wins that are simple to keep up.
Mark the cuff
A dot of tape on the cuff shows where it sat last time, so the next reading starts the same way.
Tilt the monitor
Lowering the screen slightly lets your eyelids cover more of the eye.
Two cloths, not one
Keep a spare microfibre cloth so a clean one is always ready.
Check your bite
Lips together, teeth apart: a quick reset whenever you notice clenching.
