Chalazion: causes, symptoms, and when to act

A chalazion is a small, firm, usually painless lump that forms inside the eyelid when one of the eyelid’s oil glands becomes blocked. Most fade over weeks to a few months, and consistent home care — warm compresses plus gentle lid cleaning — resolves most of them without any procedure. This page is the starting point for everything about chalazia: what causes them, how to tell one from a stye, which treatments actually help, and the signs that mean it is time to see a doctor.

What is a chalazion?

A chalazion is a localized inflammatory lump that develops when a meibomian gland — one of the tiny oil glands embedded in the eyelid — becomes blocked and its trapped oil leaks into the surrounding tissue.

The meibomian glands line both the upper and lower lids and open along the lid margin, where they release the oily outer layer of the tear film. When an outlet clogs, oil backs up inside the gland. The gland swells, and the body responds with slow, sterile inflammation that walls the oil off into a firm, round nodule under the skin. That inflammation — not infection — is why a chalazion typically hurts far less than a stye. Upper lids, which carry more glands, are affected more often than lower ones.

Chalazion symptoms: what it feels like

• A firm, round lump under the skin of the eyelid, usually pea-sized or smaller
• Little or no pain, sometimes mild tenderness when pressed
• Mild redness of the overlying lid in the first days, which fades
• Blurred vision if a large lump presses on the eyeball
• Watering or a mild scratchy sensation
• One lump or several at a time, sometimes on both eyes

A useful pattern to know: a bump that began red and painful, then settled into a painless lump, was likely a stye that evolved into a chalazion as the infection burned out and the gland stayed blocked. That sequence is common and usually still resolves with home care.

Chalazion or stye: key differences

Because the two are confused constantly, the fastest triage is a side-by-side comparison. A stye is an active infection at the lash line and usually hurts; a chalazion is sterile inflammation deeper in the lid and usually does not.

If your lump is painful and sits right at the lash line, read our stye guide. If you are still unsure, the full chalazion vs stye comparison walks through the diagnosis in detail.

What causes a chalazion?

Anything that thickens the gland’s oil or blocks its opening can start one:

• Blepharitis — chronic inflammation of the lid margin, the most common background condition
• A previous stye in the same gland that healed into a blocked duct
• Thicker-than-normal oil secretions that drain poorly, as in some skin and gland disorders
• Habitual eye rubbing and transferring bacteria from hands to lids
• Old or shared eye makeup clogging the lid margin

Recurrence is common: once a gland has blocked, the same spot can plug again, and people prone to blepharitis often see repeated lumps. Multiple or recurring chalazia are a reason to be evaluated by an eye doctor rather than to keep restarting compresses.

Chalazion treatment: what helps and what doesn’t

Home care: warm compresses and lid hygiene

First-line treatment is the same in nearly every clinical guideline: heat, gentle massage, and cleanliness.

1. Wash your hands before touching the eyelid.
2. Soak a clean washcloth in warm — not hot — water and wring it out.
3. Hold it over the closed eyelid for 10 to 15 minutes, rewarming as it cools; most sources recommend this 3 to 4 times a day.
4. After the compress, gently massage the lid over the lump with a clean finger for a minute to help move the softened oil out.
5. Once a day, clean the lid margin with a cotton pad and a drop of mild cleanser or diluted baby shampoo, then rinse.

Expect gradual change, not overnight results. The full protocol, common mistakes, and evidence for each step are detailed in chalazion treatment. Do not squeeze, poke with a needle, or apply apple cider vinegar, tea tree oil, or toothpaste — none of these help, and some injure the eye surface.

In-office procedures

When a lump ignores a month of faithful compresses, or is large enough to press on the eye, an ophthalmologist can offer a steroid injection into the lump or incision and drainage — a short in-office procedure done from the inside of the lid so there is no visible scar. What each option involves, recovery, and risks are covered in chalazion removal. Cost questions get their own page: aggregated US pricing from CareCredit puts the average procedure near $804, typically ranging from $620 to $1,566 (chalazion surgery cost).

What to expect as it heals

A chalazion does not vanish on a schedule. Most shrink steadily over two to four weeks of consistent care, but a long-standing or hardened lump can take months; the Cleveland Clinic notes several weeks to a few months is normal. Our chalazion healing stages guide describes week by week what normal looks like — and what does not.

When to see a doctor

Home care is reasonable for a quiet, stable lump, but arrange an appointment if you notice:

• Vision changes or blurred vision in the eye with the lump
• Redness or swelling spreading toward the cheek or brow
• Fever alongside the eyelid swelling
• Severe pain, or pain out of proportion to the lump’s size
• A lump that keeps growing after two to three weeks of compresses
• No improvement at all after a month, or repeated lumps in the same spot
• A lump that bleeds, ulcerates, or loses lashes at its edge

A persistent lump also occasionally turns out to be something other than a chalazion, which is itself a reason for a professional exam rather than more compresses.

Prevention

• Run a simple lid-hygiene routine — a minute of lid-margin cleaning — several times a week if you are prone to lumps
• Start warm compresses at the first hint of a new blockage; early ones drain most easily
• Remove all eye makeup before sleeping, and replace products every few months
• Never share eye makeup, brushes, or towels
• Avoid rubbing your eyes, and wash hands before touching your face

FAQ

Is a chalazion serious?

In most cases, no. A chalazion is a sterile inflammatory lump, not an infection or tumor. It becomes a concern if it presses on the eye and blurs vision, keeps growing, or keeps returning to the same spot.

Will a chalazion go away on its own?

Often, yes. Many chalazia shrink and disappear over weeks to a few months, and consistent warm compresses with lid hygiene help most of them along. One that stays unchanged after a month deserves a professional look.

Can I pop or squeeze a chalazion?

No. Never squeeze, pop, cut, or poke a chalazion. Forcing it open can push inflammation deeper, cause bleeding, and scar the eyelid. Only a trained clinician should drain one, in a clean setting.

How long does a chalazion last?

The Cleveland Clinic notes a chalazion can last several weeks to a few months, especially if the gland stays blocked. Compresses and lid hygiene started early tend to shorten that window.

Why do I keep getting chalazia?

Recurrence is common and usually points to an underlying lid-margin problem such as blepharitis, thicker-than-usual gland oil, or incomplete drainage of an earlier lump. Recurrent or multiple lumps should be evaluated by an eye doctor.

How much does chalazion removal cost?

Aggregated US pricing from CareCredit puts the average removal near $804, with a typical range of $620 to $1,566. Insurance often covers removal when the lump affects vision or keeps returning.
