Chalazion vs Stye: How to Tell Them Apart and What Helps

October 31, 2026

A stye (hordeolum) is a red, painful bump at the edge of the eyelid. It is usually a bacterial infection of an eyelash follicle or oil gland [1,2]. A chalazion is a firm, usually painless lump deeper in the lid, caused by a blocked oil gland rather than an infection [1,3].

Both usually get better with warm compresses. Most styes drain within 2 to 4 days, while a chalazion can take 2 to 8 weeks to go away [2].

Key takeaways

  • A stye is a painful, infected bump at the lash line. A chalazion is a firm, mostly painless lump from a blocked oil gland.
  • In the first day or two, the two can look the same. The difference becomes clearer as the bump settles.
  • Warm compresses are the first treatment for both. Never squeeze, pop or prick an eyelid bump.
  • Antibiotic drops usually do not help either one. Antibiotic pills are mainly for infection that spreads into the eyelid.
  • A chalazion that lasts, grows or blurs vision can be treated with a steroid injection or drained by an eye doctor.
  • Get urgent care for vision changes, fever, pain when moving the eye, or redness spreading across the lid.

This article is general education, not a diagnosis. If you are unsure what an eyelid bump is, or it is getting worse, have it checked by an eye doctor.

Chalazion vs stye: what's the difference?

A stye is an acute infection, usually with staph bacteria, of an eyelash follicle or a small oil gland in the eyelid. It is painful and usually sits at the lid edge. A chalazion forms when an oil gland, called a meibomian gland, gets blocked. It is not an infection, is usually painless, and sits farther back in the lid [1,2].

FeatureStye (hordeolum)Chalazion
What it isAn infected eyelash follicle or oil gland [1]A blocked oil gland with inflammation around it, not an infection [1]
CauseBacteria, usually staph [2,4]Thick or trapped oil in a meibomian gland [1]
PainPainful and tender [2]Usually painless after the first few days [2]
WhereAt the lash line, or on the inner side of the lid (internal stye) [1]In the body of the lid, set back from the lashes [1]

First treatmentWarm compresses. Do not squeeze [2,5]Warm compresses. Do not squeeze [2,3]
If it lastsA doctor may open and drain it [1,5]Steroid injection or drainage [1,3]

Early on, a chalazion can look exactly like a stye [1]. A chalazion often follows an internal stye. The redness and pain fade, but the blocked gland does not drain and leaves a firm, non-tender lump [3].

Left, labeled 'External stye': an eye with a small orange-outlined bump right at the edge of the upper lid near the lashes, with the text 'A tender focus can form near the root of a lash.' Right, labeled 'Chalazion': an eye with a larger round orange-outlined bump set higher in the upper lid, with the text 'Blocked gland material can form a deeper nodule.'
An external stye forms at the root of a lash, while a chalazion forms deeper in the lid from a blocked oil gland.

When to see a doctor about a stye or chalazion

Most styes and chalazia heal with home care. But infection can spread into the eyelid, and a few lumps are not what they seem [1,5].

Get emergency care now if:

  • Your vision suddenly drops or you see double, along with eyelid swelling [6].
  • It hurts to move your eye, or the eye bulges forward [6].
  • Swelling spreads across the lid or face with fever, especially in a child [5,6].

See a doctor soon if:

  • The bump is not better after a week or two of home care, or keeps getting bigger [3,5].
  • It is very large or very painful, or your whole eyelid or eye turns red [5].
  • The bump bleeds, or you lose eyelashes over it [3,5].
  • Your vision is blurry, or a child's lump presses on the eye [1,7].
  • A new stye appears soon after one heals, or a lump returns in the same spot [1,5].

See Netra's guide to urgent vision changes for other warning signs.

What is a stye, and what does it look like?

A stye is a red, swollen bump on the edge of the eyelid. It looks like a pimple and is tender to touch [5]. It usually grows over a few days and may form a small yellow spot at the base of a lash. The eye may water, feel gritty, or be sensitive to light [2,5].

There are two types. An external stye forms at the base of an eyelash and is the most common [1]. An internal stye forms in a meibomian gland on the inner side of the lid. It can be more painful and swollen, rarely bursts on its own, and tends to come back [1,2].

If redness spreads across the whole eyelid, the infection may have moved into the lid tissue (eyelid cellulitis). This can need antibiotic pills and should be seen by a doctor [1,5].

What causes a stye?

A stye starts when an oil gland or eyelash follicle at the lid edge gets blocked and bacteria grow inside it [5]. The usual germ is Staphylococcus aureus (staph) [2,4]. Repeated styes are linked to blepharitis, rosacea and diabetes, and Demodex eyelash mites can make styes worse [4,5].

If you get styes often, ask your eye doctor to check for an ongoing lid condition. Netra's guides to Demodex blepharitis and ocular rosacea explain two common ones.

What is a chalazion, and what else causes a painless eyelid lump?

A chalazion is a small, firm lump caused by a blocked meibomian gland. These oil glands sit in the lid just behind the lashes [3]. It grows slowly and is usually painless [2,8]. Other painless eyelid bumps include yellow patches called xanthelasma, small skin-colored growths (papillomas), and cysts [5].

Meibomian glands make an oily fluid that helps keep the eye's surface moist [3]. Netra's article on tear film layers explains how this oil works. When these glands make thick oil, as in meibomian gland dysfunction or rosacea, chalazia are more likely [1].

A large chalazion can press on the front of the eye and change its shape. That can cause blurry vision from astigmatism [1]. Rarely, an eyelid skin cancer can look like a chalazion [3].

How do you get rid of a stye?

Most styes go away on their own. To help one drain, hold a clean, warm, wet cloth on the closed eyelid for about 10 minutes, several times a day [2,5]. Do not squeeze or pop it. Skip eye makeup and contact lenses until it heals, and see a doctor if it is not better in a week or two [5].

How to use a warm compress safely

  1. Wash your hands.
  2. Soak a clean washcloth in warm water. It should be no hotter than you can comfortably hold your hand in [3].
  3. Close your eye and rest the cloth gently on the lid for 5 to 15 minutes. Rewarm it when it cools [2,3].
  4. Repeat several times a day. Medical sources suggest 2 to 4 or more sessions a day [2,3,5].
  5. Use a fresh cloth each time, and do not share it.

The same routine is the first treatment for a chalazion. Warmth may soften the hardened oil blocking the gland so it can drain [3]. If your doctor suggests gentle lid massage, ask them to show you how, and never press on the eyeball.

What not to do

  • Do not squeeze, pop or prick a stye or chalazion. Let it drain on its own [3,5].
  • Do not try to open it with a needle. If it needs draining, an eye doctor can do it in the office [5].
  • Do not wear eye makeup or contact lenses until the area heals [5].
  • Do not use leftover or borrowed antibiotic or steroid drops.

If a stye drains by itself, gently clean the outside of the lid and wash your hands.

Can you get rid of a stye overnight?

No home remedy is proven to clear a stye overnight. Warm compresses help it come to a head and drain, which usually happens within 2 to 4 days [2]. Squeezing it to speed things up is not safe [5]. If a stye is very painful or not improving, an eye doctor can open and drain it [1,5].

How long does a stye last?

Most styes come to a head and drain within 2 to 4 days, and the pain eases once they drain [2]. A chalazion takes longer. Most go away without treatment within 2 to 8 weeks [2]. See a doctor if a stye is not improving after a week or two, or if a chalazion keeps growing [3,5].

Older chalazia are harder to clear with home care. In a trial of 149 people, only about 1 in 5 chalazia fully cleared after 4 to 6 weeks of warm compresses [9]. On average, lumps shrank by about 1 to 2 mm [9]. Lumps that cleared had been present for a shorter time, about 1.5 months versus 2.2 months [9]. The authors suggested considering a procedure for chalazia present more than 2 months [9].

Do antibiotics help a stye or chalazion?

Usually not. A chalazion is not an infection, so antibiotics rarely help. Antibiotic drops or ointment usually do not help much for a simple stye either [2]. Antibiotic pills are used when infection spreads into the eyelid (cellulitis) and for some internal styes [1].

Studies agree. In the trial above, adding tobramycin drops, or tobramycin with a steroid, did not help chalazia clear [9]. A review of 2,712 patient records found antibiotics were used in about 1 in 3 cases. They did not improve healing of styes or chalazia [10]. If you are prescribed an antibiotic, ask what it is meant to treat.

What if a chalazion won't go away?

If a chalazion lasts more than several weeks despite warm compresses, is large, or blurs vision, an eye doctor can treat it. Options are a small steroid injection into the lump, or opening and draining it, usually from inside the lid (incision and curettage) [1,3]. A lump that keeps returning may need a biopsy [1].

FeatureSteroid injectionIncision and curettage (drainage)
What happensA small dose of steroid (triamcinolone) is injected to calm the inflammation [1,11]The lump is opened, usually from inside the lid, and its contents removed [3]
Results in trialsAbout 81% to 84% cleared [11,12]About 79% to 87% cleared [11,12]
ComfortLess pain and inconvenience in one trial [12]More pain than injection in one trial [12]
Possible side effectsLighter skin at the injection site, more common in darker skin [13]. Case reports describe thinning of the fat under the skin [14]Eyelash loss, a small notch in the lid edge or, rarely, a skin scar [3]

In one trial, based on patient reports by phone at 3 weeks, 46% of chalazia cleared with warm compresses alone. That compared with 84% after injection and 87% after drainage [12]. In another trial, lumps cleared about 5 days after an injection on average [11]. Those authors suggested injection when the diagnosis is clear and no biopsy is needed [11]. Both were small, single-hospital studies.

Before a procedure, tell the doctor about blood thinners, but do not stop them on your own. Ask whether you can drive home if the eye will be covered. Chalazia can come back after they heal [3].

Why do styes or chalazia keep coming back?

Repeated styes or chalazia usually point to an ongoing eyelid problem, such as blepharitis, meibomian gland dysfunction, Demodex mites or rosacea [1,4,5]. Treating that condition may help prevent new lumps [5]. A lump that returns in exactly the same spot is different. It needs an exam and possibly a biopsy [1,8].

For prevention, MedlinePlus suggests a daily warm compress followed by gentle cleaning along the lash line with eye cleansing pads or diluted baby shampoo [3]. Tear-free shampoos contain surfactants, which were a common cause of allergic eyelid dermatitis in one patch-test study [15]. If a cleanser makes your lids red or itchy, stop it and ask your doctor about other options.

Ask for a closer look if a lump returns in the same place, keeps growing, bleeds, or causes eyelash loss [3,5]. Recurrent chalazia should be checked for cancer, which is rare [3,8]. A biopsy request does not mean cancer has been found; it is how doctors rule it out [1]. Netra's guide to dry eye and meibomian gland testing explains how doctors check the oil glands.

Do styes and chalazia in children need special care?

The same home care usually works, but children need closer watching. In young children, chalazia are linked with astigmatism [7]. The risk is higher when the lump is on the upper lid, is 3 mm or larger, or there is more than one [7]. Untreated focusing problems can lead to a lazy eye (amblyopia) [16].

In a study of 381 children with chalazia, those aged 4 to 8 more often had focusing problems linked to amblyopia [16]. Orbital cellulitis, a deep infection around the eye, can get worse very quickly in children and threaten vision [6].

Have a child's eyes checked if a lump is large, presses on the eye, or keeps coming back. Also get a check if the child squints, rubs or closes one eye. Test the compress on your own wrist first. Netra's guide to children's vision warning signs lists other reasons for an exam.

Can Netra Restoration Therapy help with styes or chalazia?

No. Netra Restoration Therapy (NRT) is not a treatment for styes or chalazia, and it has not been tested in controlled trials for either one. It cannot drain a stye, remove a chalazion, or show whether a lump is harmless. Use the standard care above, and never delay seeing an eye doctor to try complementary care.

Netra describes Netra Restoration Therapy as adjunctive care based on principles from Traditional Chinese Medicine and Ayurveda. It is used alongside, not instead of, care from an eye doctor, and Netra states that it is not a cure [17].

Some people with repeated lumps also have ongoing burning or gritty eyes from meibomian gland dysfunction, rosacea or evaporative dry eye. If they ask about complementary care for that discomfort, it should only be added to their eye doctor's plan. The lumps still follow standard care.

Evidence here is limited. In one small sham-controlled dry-eye trial of 49 people, acupuncture improved some symptom scores but not tear or eye-surface tests [18]. That trial did not test NRT and did not include styes or chalazia. Netra's NRT effectiveness page explains why it judges results condition by condition and does not guarantee outcomes [19].

Do not put herbal oils, balms or unprescribed drops on an inflamed eyelid. Tell your eye doctor about any complementary care, especially before a procedure.

Frequently asked questions

Is a stye contagious?

A chalazion is not contagious because it is not an infection. A stye is caused by bacteria, usually staph, so it makes sense to keep those germs to yourself. Wash your hands before and after touching your eye, do not share towels, and skip eye makeup and contact lenses until it heals.

Can a stye turn into a chalazion?

Yes. If a stye's blocked gland does not drain, the redness and pain can fade while a firm, painless lump stays behind. That lump is a chalazion, and it can take several weeks to go away.

Should I pop a stye or chalazion?

No. Squeezing, popping or pricking an eyelid bump is not safe. Let it drain on its own with warm compresses. If it needs draining, an eye doctor can open it safely in the office.

Can I wear makeup or contact lenses with a stye?

It is best to skip eye makeup and contact lenses until a stye has fully healed. Wear glasses instead, and wash your hands before touching your eyes. Do not share eye makeup with anyone.

Is a chalazion dangerous?

A chalazion is almost always harmless and often goes away on its own. Rarely, an eyelid cancer can look like a chalazion. See an eye doctor if a lump keeps growing, comes back in the same spot, bleeds, or causes eyelash loss.

Does a chalazion go away on its own?

Yes, most chalazia go away without treatment within 2 to 8 weeks. Warm compresses several times a day may help. If a chalazion lasts longer, is large, or blurs your vision, an eye doctor can inject or drain it.

Can I go to work or school with a stye or chalazion?

Usually yes, if you feel well and can see clearly. Wash your hands often and do not share towels. See a doctor instead if you have a fever, redness spreading across the lid, or trouble seeing.

How can I prevent styes and chalazia?

Wash your hands before touching your eyes, and keep your eyelids clean. If you get them often, a daily warm compress followed by gentle cleaning along the lash line may help. Treating blepharitis or Demodex mites, if you have them, may also help prevent repeat styes.
