Most cases of pink eye clear up within 7 to 14 days without treatment. The exact timeline depends on what’s causing it: viral, bacterial, or allergic conjunctivitis each follow different patterns and respond to different approaches. Viral pink eye, the most common type, can sometimes linger for 2 to 3 weeks or more.
Viral Pink Eye: 1 to 3 Weeks
Viral conjunctivitis is the most common form, and unfortunately, it’s also the one you can’t really speed up. There are no drops or medications that kill the virus. It simply has to run its course, which typically takes 2 to 3 weeks according to the Mayo Clinic, though milder cases can resolve in 7 to 14 days.
Symptoms usually follow a predictable arc. The first few days tend to be the worst, with heavy watering, redness, and a gritty or burning sensation. You may wake up with your eyelids stuck together from dried discharge, though the discharge itself is usually watery rather than thick. By the end of the first week, most people notice the wateriness and irritation starting to ease. Redness is often the last symptom to fully fade, sometimes persisting a few days after everything else feels normal.
Viral pink eye often starts in one eye and spreads to the other within a day or two. If your second eye gets involved, its timeline essentially resets from the point of infection, so you may feel like the illness drags on longer than expected.
Bacterial Pink Eye: 2 to 5 Days With Treatment
Bacterial conjunctivitis produces thicker, yellow-green discharge and tends to make the eyelids noticeably crusty. Left untreated, it can take up to 10 days to resolve on its own, but antibiotic eye drops or ointment shorten that significantly. Most people see clear improvement within 2 to 3 days of starting treatment, with full resolution within about 5 days.
One practical detail worth knowing: you remain contagious for about 48 hours after starting antibiotics. The American Academy of Ophthalmology recommends swapping out your pillowcases and towels at that 48-hour mark, then resuming your normal routine. Before that point, treat everything your eyes touch as potentially spreading the infection.
Allergic Pink Eye: Hours to Months
Allergic conjunctivitis behaves completely differently from the infectious types. Your timeline depends entirely on what’s triggering the reaction and whether you can get away from it. If you’re reacting to a pet or a specific product, removing the allergen can bring relief relatively quickly. Oral antihistamines start working in about 30 minutes, and allergy eye drops kick in after roughly an hour.
Seasonal allergies are trickier. If pollen is the culprit, your symptoms may persist for weeks or even months during peak season. The eyes can stay red, itchy, and watery as long as the exposure continues. The hallmark of allergic conjunctivitis is intense itching in both eyes, which helps distinguish it from viral or bacterial types. It’s not contagious.
How to Tell It’s Getting Better
Healing tends to happen gradually rather than overnight. The first sign things are improving is usually a decrease in discharge. If you’re waking up with less crusting on your lashes or producing fewer tears during the day, that’s a good indicator. Irritation and the “something in my eye” sensation typically ease next. Redness fades last and can take several days after your eye otherwise feels fine.
If your symptoms are getting worse after 5 to 7 days rather than better, or if you develop significant eye pain, sensitivity to light, or blurred vision that doesn’t clear when you blink, something else may be going on. These symptoms can signal a more serious eye condition that needs professional evaluation.
What Actually Helps (and What Doesn’t)
For viral pink eye, treatment is purely about comfort. Artificial tears (available over the counter) help soothe the irritation and flush away discharge. A cool, damp compress held gently against closed eyes for a few minutes can ease the burning sensation. Neither of these will shorten the infection, but they make the wait more tolerable.
If you wear contact lenses, stop immediately and switch to glasses until the infection fully clears. Contacts trap irritants and bacteria against the eye and can significantly delay healing. Throw away any lenses you were wearing when symptoms started, along with any lens solution from that period.
Avoid rubbing your eyes, even though they itch. Rubbing spreads the infection between eyes (or to other people via your hands) and can irritate already inflamed tissue. Wash your hands frequently, especially after touching your face.
How Long Before You Can Go Back to Work or School
This varies by type. With bacterial pink eye, most schools and workplaces allow you to return 24 to 48 hours after starting antibiotic drops, once active symptoms are improving. The CDC’s guidance is more flexible than many people expect: if you don’t have a fever or other symptoms, you may be allowed to return with a doctor’s approval, even without waiting a set number of days. The key consideration is whether your activities involve close contact with others.
Viral pink eye is contagious for as long as your eyes are red and tearing, which can mean 10 to 14 days. That’s a long time to stay home, and many people do return to work or school earlier while taking precautions like frequent handwashing and avoiding touching their face. Children in daycare or school settings are often held to stricter rules.
Allergic conjunctivitis isn’t contagious at all, so there’s no medical reason to stay home unless your symptoms are too uncomfortable to function.
