Most styes clear up on their own within two to five days, and the single most effective thing you can do is apply a warm compress consistently. A stye is a small, painful bump that forms when bacteria infect an oil gland or hair follicle along your eyelid margin. While it looks alarming, it rarely requires medical treatment.
What Causes a Stye
Staphylococcus aureus, a common skin bacterium, is the usual culprit. It gets into one of the tiny glands that line your eyelid and triggers an acute infection. External styes form in the glands attached to your eyelash follicles, right at the lid margin where you can see and feel them. Internal styes develop deeper, in the oil-producing meibomian glands on the inner surface of the eyelid. Internal styes tend to be more painful and slower to resolve because they’re harder to drain.
Touching your eyes with unwashed hands, sleeping in old makeup, or wearing contact lenses with poor hygiene all increase your risk. Some people are simply more prone to styes because their eyelid glands produce thicker oil that clogs more easily.
Warm Compresses Are the First-Line Treatment
Soak a clean washcloth in warm water, wring it out, and hold it gently against the affected eye for five minutes. Do this several times a day. The heat softens the clogged material inside the gland and encourages the stye to drain naturally. You’ll likely need to re-wet the cloth once or twice during each session to keep it warm.
This is not just a folk remedy. Warm compresses are the standard recommendation from ophthalmologists and the treatment most likely to speed resolution. The goal is to get the blocked gland to open and release the trapped oil and pus. Most styes will begin shrinking within a couple of days of consistent compress use, though some take a week or longer.
A few things to avoid while you’re waiting it out: don’t squeeze or pop the stye. Pressing on it can push the infection deeper into the eyelid or spread bacteria to surrounding tissue. Let it drain on its own.
Contact Lenses and Makeup
If the bump is actively infected (red, swollen, tender), skip your contact lenses until it heals. The American Academy of Ophthalmology notes that contacts are generally fine with an uninfected eyelid cyst, but a true stye is an active bacterial infection, and a lens sitting against inflamed tissue can trap bacteria and slow healing.
Throw out any eye makeup you were using when the stye appeared, especially mascara and eyeliner. These products can harbor the bacteria that caused the infection in the first place. Using them again risks reinfection or spreading bacteria to the other eye.
When a Stye Needs Medical Treatment
If pain and swelling haven’t started improving after about 48 hours of home care, it’s worth seeing an eye doctor. A stye that isn’t resolving may need one of a few interventions:
- Antibiotic drops or ointment. Your doctor may prescribe a topical antibiotic to apply to the eyelid, or oral antibiotics if the surrounding skin looks infected. That said, clinical evidence for topical antibiotics alone is surprisingly weak. A randomized trial found that antibiotic eye drops after drainage produced no better outcomes than artificial tears, and there’s no real consensus on an optimal treatment protocol. Antibiotics matter most when the infection is spreading beyond the stye itself.
- Incision and drainage. For a stubborn or large stye, your doctor can make a small cut under local anesthesia to release the trapped material. This is a quick in-office procedure and provides fast relief.
- Steroid injection. If significant swelling persists, a steroid injection into the eyelid can bring it down. This is more common with internal styes that have become chronic.
Signs of a More Serious Problem
A stye that worsens instead of improving can occasionally lead to preseptal cellulitis, a skin infection that spreads across the tissue around the eye. Watch for these warning signs:
- Swelling so severe your eye swells shut
- Pus or blood leaking from the bump
- Pain and swelling that keep increasing after the first two to three days
- Blisters forming on the eyelid
- Eyelids that feel hot to the touch
- Changes in your vision
- Fever along with eye pain and swelling
Fever combined with swelling around the entire eye socket is an emergency. Preseptal cellulitis can progress to orbital cellulitis, a deeper and more dangerous infection. Children are particularly susceptible to this progression.
Preventing Styes From Coming Back
If you get styes repeatedly, the issue is usually chronic bacterial buildup or clogged oil glands along the lash line. Daily eyelid hygiene can break the cycle.
Eyelid scrubs, either pre-moistened wipes or a diluted cleanser applied with a cotton pad, wash away the bacteria, oil, and debris that accumulate at the base of your lashes. Products containing tea tree oil are particularly useful because they kill Demodex mites, tiny organisms that live in eyelash follicles and contribute to chronic eyelid inflammation. Full-strength tea tree oil is too harsh for the delicate skin around your eyes. Look for a product formulated at around 25% concentration, or dilute one drop of tea tree oil in two to three drops of water or coconut oil and apply it with a cotton swab.
Hypochlorous acid sprays are another option. They sound intense, but they’re gentle enough for daily use and mimic the way your immune system naturally fights germs. They kill bacteria and reduce inflammation without irritating the skin. Both tea tree oil products and hypochlorous acid sprays are available over the counter at most pharmacies.
Beyond eyelid-specific products, the basics matter: wash your hands before touching your face, replace mascara every three months, remove all eye makeup before bed, and clean your contact lenses according to their recommended schedule. For people prone to recurrent styes, a nightly warm compress routine (even when no stye is present) helps keep the oil glands flowing freely and reduces the likelihood of another blockage.
