You woke up with a red, tender, painful lump on your eyelid — blinking suddenly hurts, the mirror is not encouraging, and Google has already managed to scare you. So first, some reassurance: a stye is one of the most common problems I see in clinic, it almost always resolves by itself, and in most cases the right treatment is simple and done at home. But there are a few things genuinely worth knowing — the difference between a stye and a chalazion, what actually speeds up healing (and what only sounds like it does), why you must never squeeze, and when it really is time to see an ophthalmologist.
What exactly is a stye?
A stye (medical name: hordeolum) is an acute bacterial infection of one of the glands in the eyelid, in most cases by staphylococcus bacteria. The result is exactly what you feel: a red, swollen, painful bump that resembles a pimple — because in essence it really is close to one.
It helps to know that the eyelid contains two types of glands that can become infected, so there are two types of stye:
- External stye — infection of an eyelash follicle or a small oil gland at the lid margin. This is the “classic” stye: a bump at the edge of the eyelid, sometimes with a yellowish point resembling the head of a pimple.
- Internal stye (a stye inside the eyelid) — infection of a meibomian gland, one of the oil-secreting glands within the thickness of the eyelid itself. This kind looks and feels like a deeper lump inside the lid, usually hurts more, and is sometimes seen best when the eyelid is gently everted.
A stye can appear on the upper or lower eyelid, and treatment is essentially the same. It is common at every age — including in children.
Stye or chalazion? The distinction everyone confuses
This is probably the point that causes the most confusion, both online and in clinic conversations, so let’s set it straight:
A stye (hordeolum) is an active infection: it appears fast, hurts, and is red and warm. A chalazion is a different story — an inflammatory lump that forms when a meibomian gland becomes blocked and the oil inside triggers an inflammatory reaction in the tissue, without an active bacterial infection. A chalazion is usually painless, develops slowly, and can sit in the eyelid for weeks or even months as a round, firm lump.
And here is the connection between the two: an internal stye that never drained completely can “cool down” and become a chalazion. This is the scenario I see most often: the pain and redness have passed, but a small firm lump remains and will not budge. That is no longer an infection — which is why antibiotics will not help it — but an inflammatory lump requiring a different approach: continued warm compresses with patience, and if it is stubborn, a local steroid injection or minor drainage in clinic.
Why does it happen — and why you?
A single stye can happen to anyone, with no particular reason. But when you look at people who get styes again and again, there is almost always a shared background:
- Blepharitis — chronic inflammation of the eyelid margins. This is the most common underlying factor. Inflamed lids with an accumulation of debris and bacteria are fertile ground for gland infections.
- Meibomian gland dysfunction (MGD). When the oil these glands secrete is too thick, the glands block easily — and a blockage is the first step toward both an internal stye and a chalazion.
- Demodex — a microscopic mite that lives in lash follicles and is involved in some cases of stubborn blepharitis and recurrent styes.
- Everyday habits: touching the eyes with unwashed hands, old or contaminated eye makeup (mascara is the main suspect), sleeping with makeup on, and poorly maintained contact lenses.
- General conditions such as diabetes and inflammatory skin diseases (rosacea, seborrhoea) also increase the tendency.
The important point: if this is your third or fourth stye this year, the problem is probably not “bad luck” but an untreated chronic eyelid condition. In that case it pays to treat the cause, not just the result — more on that below.
The symptoms: what you will feel
The typical picture is easy to recognise: a red, tender bump on the eyelid that appeared within a day or two, local swelling, pain on touch and on blinking, sometimes increased tearing, a gritty foreign-body sensation, and occasionally crusting or mild discharge in the morning. With an external stye you may see a yellowish point on the bump — a sign it is “ripening” and close to draining.
What I most want you to know is what is not supposed to happen: a stye should not affect your vision, should not swell the entire eyelid to the point you struggle to open the eye, and should not come with fever or feeling generally unwell. Those are signs the infection is extending beyond the gland — and then you do not wait, you get examined.
Treatment: what actually helps
The simple truth is that most styes will resolve on their own within days to two weeks. The job of home treatment is to speed drainage and ease the pain — and your job is mainly to do no harm. Here is how to do it right:
Warm compresses — this IS the treatment. Not “another recommendation,” but the foundation everything rests on. Gentle, sustained warmth softens the thick oil blocking the gland and lets the stye drain naturally. Place a warm (not scalding) compress on the closed eye for 10–15 minutes, three to four times a day, and after the warmth you can gently massage the lid toward the lash margin. Consistency matters far more than intensity — a lukewarm compress for thirty seconds does nothing.
Keep the area clean — gently. Gentle cleaning of the lid margins with dedicated lid wipes or a little diluted baby shampoo helps reduce the bacterial load. No scrubbing needed.
A simple painkiller such as paracetamol or ibuprofen is entirely legitimate if it hurts.
And on the “don’t” side: do not squeeze and do not try to pop it — squeezing spreads the infection into surrounding tissue and can turn a small problem into a big one. Avoid eye makeup and contact lenses until the stye resolves. And do not share towels or makeup with others while the stye is active.
What about antibiotic ointments and drops?
I get asked about this a lot, partly because in Israel there is a reflex to smear ointment on anything on an eyelid. Let’s be precise: for a simple stye, antibiotic drops or ointments are usually unnecessary and do not meaningfully shorten the course — the infection sits deep inside the gland, and medication applied from outside barely reaches it. Topical antibiotics do enter the picture when there is significant blepharitis in the background, frank purulent discharge, or after drainage. Oral antibiotics are reserved for situations where infection spreads into the eyelid tissues (cellulitis) — a situation that requires a doctor’s examination anyway. That is exactly why I would rather you invest in proper compresses than chase a prescription.
When the stye refuses to leave
If after two to three weeks of consistent home treatment the lump is still there — it has most likely become a chalazion, and the clinic options are a local steroid injection to shrink the inflammatory lump, or minor surgical drainage: a short procedure under local anaesthesia, through the inner side of the eyelid (so there is usually no visible scar). Both options are simple and effective, and the choice between them depends on the lump’s size, location, and your preference.
Recurrent styes: treat the cause, not just the lump
If you are a “subscriber” to styes — this section is for you. Recurrent styes are almost always the expression of chronic eyelid disease: blepharitis, MGD, and sometimes Demodex. The right treatment in that case is not another round of compresses every time a lump appears, but a steady routine that prevents the blockage in the first place: daily lid hygiene, a regular warm compress (even when there is no stye!), treating blepharitis and Demodex if present, and in suitable cases — dedicated treatments to improve meibomian gland function, such as professional gland expression or IPL treatment, which addresses the root of the problem in a substantial share of patients.
Basic prevention is good for everyone, including after a first stye: replace mascara and eye makeup every few months, remove makeup before sleep, maintain contact lens hygiene, and avoid touching your eyes as much as possible.
When to see an ophthalmologist — without hesitating
In most cases it is absolutely fine to start at home. But there are situations where I ask you not to delay:
- Swelling or redness spreading beyond the lump — to the whole eyelid, and certainly to the cheek or brow
- Any change in vision
- Severe pain that worsens instead of improving
- Fever or feeling generally unwell
- A stye in a child with significant swelling — in children, eyelid infections can spread faster
- A lump that has not improved after two weeks of consistent home treatment, or one that keeps returning in the same spot
That last point matters in particular: a lump that recurs in exactly the same place on the eyelid, or one that looks “asymmetric” and steadily grows, deserves examination also to rule out rarer but more important diagnoses. No reason for alarm — but a good reason to be checked.
I perform these examinations and treatments — including chalazion drainage, blepharitis care, and management of recurrent styes — at my clinic in Haifa, serving patients from across northern Israel. If your stye is stubborn, recurrent, or simply worrying you — you are welcome to get in touch and book an examination. We will take a look, make sense of it, and build a plan together so the next stye never appears.
Frequently Asked Questions
How long does a stye last? Most styes drain and resolve on their own within a few days to two weeks, especially with regular warm compresses. If the lump has not shrunk after two to three weeks, or it has stopped hurting but remains as a firm bump — it may have become a chalazion, and it is worth being examined by an ophthalmologist.
What is the difference between a stye and a chalazion? A stye (hordeolum) is an acute bacterial infection of a gland in the eyelid — it is painful, red, and develops quickly. A chalazion is a non-infected inflammatory lump that forms when a meibomian gland becomes blocked — it is usually painless, develops slowly, and can persist for weeks. A stye that never fully drains may turn into a chalazion over time. Initial treatment for both is similar — warm compresses — but a stubborn chalazion may need a steroid injection or minor drainage.
Can I pop or squeeze a stye? No. Squeezing a stye can spread the infection into the surrounding eyelid tissue and make things worse. A stye drains on its own when it is ready, and warm compresses safely speed that process. If it will not drain — controlled drainage by an ophthalmologist is the right and safe way.
Is a stye contagious? A stye itself does not “jump” from person to person the way viral conjunctivitis does, but the bacteria that cause it can spread by contact. So wash your hands, avoid touching your eyes, and do not share towels, eye makeup, or applicators while a stye is active.
I keep getting styes — why? Recurrent styes are almost always a sign of an underlying chronic condition — usually blepharitis (eyelid inflammation), meibomian gland dysfunction (MGD), and sometimes Demodex. In that case the solution is not treating each stye separately but treating the cause: consistent lid hygiene, daily warm compresses, and in suitable cases dedicated treatments such as IPL. See an ophthalmologist who specialises in ocular surface disease.
When must I see a doctor about a stye? When the lump has not improved after about two weeks of compresses, when the swelling or redness spreads beyond the lump itself to the whole eyelid or the cheek, when vision is affected, when pain is severe and worsening, or when a child has marked eyelid swelling. In these situations antibiotics or drainage may be needed, and rarely there is a deeper infection requiring urgent treatment.
