Quick answer
What is stye?
A stye is a small, painful lump on or inside the eyelid, caused by a minor infection at the base of an eyelash. Styes are common and usually harmless, clearing up by themselves within a week or two. A warm compress several times a day is the main treatment.
What is a stye?
A stye is a small, painful lump on or just inside the eyelid, caused by a minor bacterial infection at the base of an eyelash or in a small eyelid gland. Styes are very common, look worse than they are, and almost always clear up by themselves.
Symptoms
A stye typically causes:
- a red, tender lump on the edge of the eyelid
- swelling of the lid
- sometimes a small yellow head of pus
- watering or a gritty feeling
Your vision should not be affected — if it is, get checked.
Treatment at home
The mainstay is warmth: hold a clean, warm compress (a flannel soaked in warm water) gently against the closed eye for 5–10 minutes, three or four times a day. This encourages the stye to drain naturally. Simple pain relief can help with discomfort.
Two important don’ts: never squeeze or burst a stye, and avoid eye make-up and contact lenses until it has fully healed.
Preventing styes
Keep eyelids clean, avoid rubbing your eyes, replace old eye make-up, and wash hands regularly — especially if you are prone to styes or have blepharitis (eyelid inflammation), which makes them more likely.
When to get help
See a GP if a stye is not improving after a couple of weeks or keeps returning. Get prompt advice if swelling spreads beyond the lid, the eye itself is red or painful, vision changes, or you feel unwell — signs the infection may be spreading.
Common questions
- What causes a stye?
- A stye is usually a small bacterial infection in an eyelash follicle or eyelid gland. They are more likely with eyelid inflammation (blepharitis), rubbing the eyes, or using old eye make-up.
- How do I get rid of a stye?
- Hold a clean, warm (not hot) compress against the closed eyelid for 5 to 10 minutes, three or four times a day. This encourages the stye to drain naturally. Pain relief can help. Most clear within a week or two.
- Should I pop a stye?
- No — never squeeze or burst a stye, as this can spread the infection. Let it drain on its own with warm compresses. Also avoid eye make-up and contact lenses until it has healed.
- Are styes contagious?
- Not in the way colds are, but the bacteria can spread via hands and towels, so wash hands regularly, avoid rubbing your eyes, and don't share towels or face cloths.
