Most cases of pink eye clear up on their own without prescription medication. Viral pink eye typically resolves in 7 to 14 days, and mild bacterial pink eye often improves in 2 to 5 days, though it can linger for up to two weeks. The key to treating pink eye at home is managing discomfort, keeping the eye clean, and preventing the infection from spreading to your other eye or to people around you.
Before you start treating at home, though, it helps to know which type you’re dealing with. The cause shapes which remedies actually work.
Figure Out Which Type You Have
Pink eye falls into three main categories, and each one looks and feels a little different.
Viral pink eye is the most common type. It often shows up alongside a cold, sore throat, or upper respiratory infection. The discharge tends to be watery rather than thick, and it frequently starts in one eye before spreading to the other. There’s no antibiotic that treats it. You simply manage symptoms while your immune system does the work.
Bacterial pink eye produces a thicker, yellowish or greenish discharge. This is the type that glues your eyelids shut overnight. The eye may be noticeably swollen and painful. Mild cases resolve without antibiotics, but more severe infections may need prescription drops.
Allergic pink eye is triggered by pollen, dust mites, pet dander, mold, or even contact lens solution. It almost always affects both eyes at once and causes intense itching. If you have a history of hay fever, asthma, or eczema, this is the most likely culprit. It’s not contagious.
Warm Compresses vs. Cold Compresses
A clean, damp washcloth held against your closed eyelids three or four times a day is the single most effective home remedy. Which temperature you choose depends on your symptoms.
Warm compresses soften and loosen the sticky crust that builds up on your eyelashes, especially overnight. This is particularly helpful for bacterial pink eye, where thick discharge mats the lids together. Soak a clean washcloth in warm water, wring it out, and hold it gently over your closed eye for a few minutes. Rewet as needed.
Cold compresses are better for itching and swelling. If you have allergic pink eye or your viral case is more uncomfortable than crusty, a cool washcloth will bring more relief. The cold helps reduce inflammation and calms that persistent urge to rub your eyes.
Use a fresh washcloth every time. If only one eye is affected, be careful not to drag the cloth from the infected eye to the healthy one.
Over-the-Counter Eye Drops
Artificial tears (lubricating eye drops) can soothe irritation from any type of pink eye. They rinse away discharge and keep the surface of the eye moist, which reduces that gritty, scratchy feeling. Look for preservative-free versions if you plan to use them frequently throughout the day.
For allergic pink eye specifically, over-the-counter antihistamine eye drops can make a significant difference. These block the allergic reaction at the source and reduce itching, redness, and watering. Some formulas combine an antihistamine with a decongestant to also shrink swollen blood vessels in the eye. These are widely available at pharmacies without a prescription.
Avoid drops marketed as “redness relievers” for prolonged use. They constrict blood vessels temporarily but can cause rebound redness when you stop using them.
Rinsing Your Eyes Safely
Gently flushing the eye with sterile saline can help wash out discharge and irritants. Store-bought sterile saline solution is the safest option. If you make your own, boil the water for at least 20 minutes and let it cool completely before use. Don’t use iodized salt, which can irritate the eye.
Homemade saline has a short shelf life. Bacteria can grow in it within 24 hours, so make a fresh batch each day and store it in the refrigerator between uses. Use a clean container every time. For most people, grabbing a bottle of sterile saline from the pharmacy is simpler and safer.
Stopping the Spread
Viral and bacterial pink eye are both highly contagious. Pink eye remains transmissible for as long as the eye is tearing and producing discharge, which can last the full recovery period of one to two weeks. A few habits make a major difference in keeping it contained.
- Wash your hands constantly. Use soap and water for at least 20 seconds, especially before and after touching your eye or applying drops. When soap isn’t available, hand sanitizer with at least 60% alcohol works.
- Don’t share personal items. Towels, washcloths, pillowcases, eye drops, makeup, and eyeglasses should all stay yours alone until the infection clears.
- Launder frequently. Wash pillowcases, sheets, towels, and washcloths in hot water with detergent. Wash your hands again after handling dirty linens.
- Stop touching your face. Every time you rub or touch the infected eye and then touch a surface, you leave the virus or bacteria behind for someone else to pick up.
What to Do About Contact Lenses and Makeup
If you wear soft, disposable contact lenses, throw away the pair you were wearing when symptoms started. Also discard your contact lens case, the solution in it, and any eye drops you were using. All of these can harbor the infection and reintroduce it after you’ve healed.
Switch to your glasses until the infection and all irritation have completely resolved. Putting contacts back in too early risks prolonging the problem or causing a recurrence. If you’re unsure whether your eyes are ready, ask your eye care provider before resuming wear.
The same logic applies to eye makeup. Mascara, eyeliner, eyeshadow, and any brushes or applicators that touched the eye area during the infection should be replaced. Reusing contaminated makeup is one of the most common ways people reinfect themselves.
Signs That Need Medical Attention
Most pink eye is a nuisance, not a danger. But some symptoms point to a more serious eye condition that looks like pink eye but isn’t. Pay attention to eye pain (not just irritation, but actual pain), blurred vision that doesn’t clear when you blink away discharge, sensitivity to light, or a persistent feeling that something is stuck in your eye. These warrant prompt medical evaluation, as they can signal infections or inflammation affecting deeper structures of the eye.
Newborns with any eye redness or discharge need immediate medical care, as certain infections in the first few weeks of life can damage vision quickly. And if your symptoms haven’t improved at all after two weeks of home care, it’s worth getting a professional assessment to rule out a bacterial infection that needs antibiotic drops or another condition entirely.
