White bump on eyelid: common causes

Noticing a white bump on your eyelid can be unsettling, but most of these bumps are benign. The cause usually becomes clearer when you look at how the bump looks, where it sits, and whether it hurts. Milia, a stye with a pus point, and various cysts can all appear as a white bump on the eyelid, and they behave differently. This article walks through the common causes, what each tends to look like, and when to see an eye doctor.

What is a chalazion?

A chalazion is a small, usually painless lump inside the eyelid caused by a blocked meibomian oil gland.

A chalazion can appear whitish or pale under the skin, which is one reason it is sometimes mistaken for a white bump on the eyelid. Meibomian glands line the upper and lower lids and release oil that keeps tears from evaporating. When one gland is blocked, the oil backs up and the surrounding tissue becomes inflamed, forming a firm, rounded bump deep in the lid. It is typically painless and grows slowly over weeks. For more detail, see our overview of chalazia and our eyelid bump guide.

Milia: tiny pearly white bumps

Milia are small, pearly white cysts filled with keratin, a protein found in skin. They often appear on the eyelid or under the eye as a tiny white bump on the eyelid that feels firm and smooth. Milia are usually painless and benign, and they do not become red or tender the way an infected bump does. They can persist for weeks to months and do not respond to squeezing. Because milia sit under intact skin, trying to pop them can injure the thin eyelid skin.

Stye with a pus point

A stye is an infection of a lash follicle or an oil gland at the lid margin. As it develops, it can form a white or yellow point — a pus point — near the surface. That white spot on the eyelid sits on a red, tender, swollen bump and is usually painful. A stye often comes on quickly, sometimes overnight, and many styes drain on their own within days to a week. A stye with a pus point is different from milia: it is red, sore, and linked to infection rather than a painless keratin cyst.

Cysts on the eyelid

Several kinds of cysts can appear as a white bump on the eyelid. A chalazion itself is a cyst-like lump from a blocked oil gland. Other benign cysts may look smooth, round, and pale or white under the lid skin. Cysts are usually slow-growing and painless, though a large one can press on the lid and feel tender. Because some eyelid growths are not cysts and a few need treatment, a bump that keeps growing or changing deserves a doctor’s exam.

Comparison: common white bump causes

Location matters too. Milia often sit on the lower lid or under the eye, while a stye tends to cluster at the lash line on the lid margin. A chalazion can sit anywhere on the lid, usually farther back from the margin than a stye. Noting where the bump appears, along with whether it hurts, gives you useful information to share with an eye doctor.

How to care for a white bump on eyelid

You can watch most white bumps at home while they settle. Follow these steps:

1. Leave the bump alone. Do not squeeze, pop, or try to drain a white bump on the eyelid at home. The lid skin is thin and delicate, and forcing a bump can spread inflammation, introduce infection, or cause scarring.
2. Use warm compresses if the bump is red and tender. Hold a clean, warm — never scalding — compress against the closed lid for 10 to 15 minutes, three to four times a day, as the American Academy of Ophthalmology recommends. This is most helpful for a stye with a pus point.
3. Keep your hands clean before and after touching the eye area.
4. Pause eye makeup until the bump settles, and replace old eye makeup afterward.
5. Track the bump over a couple of weeks. Note whether it is shrinking, staying the same, or steadily growing.
6. Book an eye doctor visit if the bump keeps growing, changes color, bleeds, or affects your vision.

When to see a doctor

Most white bumps on the eyelid are benign, but get seen promptly for any of these:

• A bump that keeps growing over weeks
• A bump that bleeds, ulcerates, or breaks through the skin
• A bump that changes color or texture
• Redness or swelling that spreads beyond the lid
• Fever along with the bump
• Pain out of proportion to the bump’s size
• Vision changes or blurry vision in the affected eye
• Bumps that keep returning in the same spot

Prevention

• Remove eye makeup before bed and replace products every few months
• Keep the lid margins clean if you have blepharitis — daily lid hygiene, not just during flare-ups
• Wash your hands before touching the eye area
• Avoid sharing towels or washcloths
• Do not rub the eyelids, which can irritate the gland openings

FAQ

What is a white bump on the eyelid?

A white bump on the eyelid is most often milia, a stye that has formed a pus point, or a cyst. Most of these bumps are benign, though a doctor should check any that grow or change.

Are white bumps on the eyelid painful?

Milia and many cysts are usually painless. A stye with a white or yellow pus point is typically tender and painful. Pain level is one clue to the cause.

Can I pop a white bump on my eyelid?

No. Never squeeze, pop, or try to drain a bump on the eyelid at home. That can spread inflammation, cause infection, or injure the delicate lid.

What are milia?

Milia are tiny, pearly white cysts filled with keratin. They often appear on the eyelid or under the eye, are painless, and are benign.

When should I see a doctor about a white bump?

See an eye doctor if the bump keeps growing, bleeds, changes color, affects your vision, or comes with spreading redness, fever, or severe pain.

Do white bumps on the eyelid go away on their own?

Many do. Milia often persist for weeks to months, while a stye pus point usually drains and heals within days to a week. A bump that does not settle should be checked.
