Why You Keep Getting Styes (and How to Stop Them)

You wake up, look in the mirror, and there it is: a sore, red bump along your eyelid that makes blinking hurt. It was not there last night. Within a day it may swell, fill with a small white head, and make your whole eye water. Then, just as it fades, another one shows up a few weeks later on the other eye.

That is a stye, one of the most common eye complaints in the United States, and also one of the most misunderstood. Most styes are not a sign of something serious, and most clear up on their own. But recurring styes usually have a cause worth fixing, and a few common habits make them worse.

What a stye actually is

A stye, also called a hordeolum, is a small, painful infection of an oil gland in your eyelid. Your eyelids contain dozens of tiny glands that release oil into your tears. That oil keeps tears from evaporating too fast and keeps your eyes comfortable.

When one of those glands gets blocked, bacteria, usually Staphylococcus aureus, a germ that normally lives harmlessly on skin, can multiply inside it. The result is a tender red bump, sometimes with a yellowish center, on the edge of the eyelid or just under the skin of the lid.

An external stye forms at the base of an eyelash and looks like a pimple on the rim of the lid. An internal stye forms deeper inside the lid and tends to hurt more, because it presses against the eyeball when you blink. Both are the same basic problem: a blocked gland plus bacteria.

A stye is not the same as a chalazion, although people confuse the two. A chalazion is a firm, usually painless lump caused by a blocked oil gland that is not infected. Styes hurt; chalazia usually do not. A stye is also not pink eye, which typically makes the whole white of the eye red and produces discharge that glues the lashes together in the morning.

Why they keep coming back

A single stye can happen to anyone. Recurring styes point to something that keeps blocking those glands or keeps bacteria close to your eyes. The most common culprits are easy to miss.

First is eyelid hygiene, or the lack of it. Old eye makeup, especially mascara and eyeliner applied right at the lash line, can plug the glands. Sleeping in makeup is one of the fastest ways to invite a stye. Sharing eye makeup, or using products that are months past their prime, adds bacteria to the mix. As a rule, replace mascara every three months and throw out anything that smells off or has been used during an eye infection.

Second is blepharitis, a chronic inflammation of the eyelid margins that makes the lids red, flaky, and itchy. People with blepharitis, rosacea, or dandruff are more likely to get styes, because their glands already tend to clog. If your eyelids are often crusty in the morning or your lashes have flakes at their bases, blepharitis may be driving the cycle.

Third is rubbing your eyes with unwashed hands. The Centers for Disease Control and Prevention stresses handwashing as a first line of defense against eye infections, and for good reason: your hands carry bacteria from phones, keyboards, and door handles straight to your eyelids. Contact lens wearers face extra risk if lenses, cases, or hands are not clean, or if lenses are worn longer than prescribed.

Stress and lack of sleep do not directly cause styes, but they can make you rub your eyes more and skip your nightly face wash.

What actually clears a stye up

For most styes, the best treatment is also the simplest: a warm compress. Soak a clean washcloth in warm water, wring it out, and hold it against the closed eyelid for 10 to 15 minutes, three to four times a day. The warmth helps the blocked gland drain on its own and eases the pain. Re-warm the cloth as it cools, and use a fresh cloth each time.

Do not squeeze or pop a stye. Pressing on it can push the infection deeper into the eyelid or spread it to nearby tissue. Do not try to lance it with a needle or pin at home, and skip over-the-counter steroid eye drops unless a doctor prescribes them, since steroids can make some eye infections worse.

Most styes improve within a few days and resolve within one to two weeks. While you have one, skip eye makeup and contact lenses until it heals, so you do not trap bacteria against the lid or contaminate your products. Wash your hands before touching your face, and avoid sharing towels or washcloths.

Antibiotic ointment is sometimes prescribed, but it is not always needed for a simple stye. The American Academy of Ophthalmology notes that warm compresses alone resolve most cases. If a stye does not start improving after several days of compresses, or keeps returning in the same spot, an eye doctor can check for an underlying problem such as blepharitis or a chalazion that needs treatment.

When to see a doctor promptly

Most styes are harmless, but get medical care quickly if the swelling spreads beyond the eyelid to the cheek or forehead, if the whole eye becomes red and painful, if your vision changes, if you develop a fever, or if the eyelid swells shut. Those signs can indicate a deeper infection called preseptal or orbital cellulitis, which needs antibiotics and should not wait.

Also see an eye doctor if a bump in the same spot never fully goes away, grows, or returns again and again. A persistent lump could be a chalazion, and in rare cases, a growth that needs to be examined to rule out something more serious. This is especially important for adults over 50 and for anyone whose eyelashes fall out around the bump.

How to stop the next one

Preventing styes comes down to keeping the eyelid glands clear and bacteria away from your eyes. A few habits make the biggest difference.

Wash your hands before touching your eyes, inserting contact lenses, or applying makeup. Remove all eye makeup every night with a gentle cleanser, and clean the lash line rather than just the skin around it. If you have flaky or crusty lids, a daily lid scrub with warm water and a drop of baby shampoo on a clean washcloth, or a commercial lid wipe, can keep blepharitis under control.

Replace eye makeup on schedule, never share it, and toss anything used while you had a stye. For contact lens wearers, follow the replacement schedule exactly, clean lenses only with fresh solution, never tap water, and replace the case every three months. Finally, resist rubbing your eyes. If they itch, a cool compress or preservative-free artificial tears are safer than your knuckles.

A stye is painful and annoying, but it is usually your eyelid asking for better hygiene, not sounding a serious alarm. Treat it gently with warm compresses, leave it alone otherwise, and fix the habit that keeps bringing it back.
