Most eye infections heal on their own within one to two weeks, but the right home care can speed your recovery and prevent complications. What you should do depends on the type of infection you’re dealing with: viral, bacterial, allergic, or a stye. Some need antibiotics, others just need time and symptom management.
Identify What Type of Infection You Have
Eye infections share overlapping symptoms like redness, tearing, a gritty feeling, and sensitivity to light. But a few distinguishing clues can help you figure out what you’re dealing with.
Bacterial conjunctivitis produces a thick, yellowish or greenish discharge. You’ll often wake up with your eyelids crusted shut. It typically affects one eye first, then may spread to the other. It frequently accompanies a cold or sore throat.
Viral conjunctivitis tends to produce a watery, clear discharge rather than thick pus. It also commonly shows up alongside cold or respiratory symptoms, and it can start in one eye before spreading to both.
Allergic conjunctivitis almost always affects both eyes at the same time and causes intense itching. If you also have sneezing and a runny nose, allergies are the likely culprit. This type isn’t truly an infection, since it’s an immune response to pollen, dust, or pet dander.
Styes look different from pink eye. They appear as a painful, red bump on or near the eyelid, caused by a blocked oil gland that becomes infected. They typically last one to two weeks and usually resolve without medical treatment.
Home Care That Actually Helps
Regardless of the type, a few simple measures relieve discomfort and support healing.
Compresses are your best tool. A warm compress (a clean, damp washcloth held over closed eyes) loosens the sticky crust and discharge that builds up overnight. A cold compress reduces itching and swelling. Apply either one three or four times a day for several minutes each time. Use a fresh section of the cloth for each eye to avoid spreading the infection.
Artificial tears, available over the counter without a prescription, help with the dryness and irritation that come with most eye infections. For allergic conjunctivitis, over-the-counter antihistamine eye drops can calm the itching and inflammation more effectively than artificial tears alone.
Keep your hands away from your eyes as much as possible, and wash them thoroughly before and after any contact with the infected area. Change your pillowcases frequently to prevent reinfection and limit spread to household members.
How to Care for a Stye
Styes respond well to warm compresses applied several times a day. The heat helps the blocked gland drain on its own. Over-the-counter pain relievers can manage the discomfort. Beyond that, follow a few key rules: don’t cover the stye with makeup, as this can plug the gland further and slow healing. Avoid touching or squeezing it. Wash your hands before and after any contact with your face, and wash your pillowcases often.
If pain and swelling haven’t started improving after 48 hours of home care, see an eye doctor. Occasionally a stye needs to be drained professionally or treated with prescription medication.
When You Need Prescription Treatment
Viral conjunctivitis has no antibiotic treatment. Like a common cold, it runs its course on its own. You manage symptoms with compresses and artificial tears while waiting it out. Viral infections typically last up to two weeks, though some stretch longer in rare cases.
Bacterial conjunctivitis sometimes clears on its own too, but antibiotic eye drops or ointment can shorten the illness and reduce the risk of spreading it to others. Bacterial infections generally last up to 10 days. If your doctor prescribes antibiotic drops, you’ll typically use them several times a day for about a week. Symptoms often start improving within the first couple of days of treatment.
Allergic conjunctivitis is treated by removing the allergen when possible and using antihistamine or anti-inflammatory eye drops. Prescription-strength options are available if over-the-counter drops aren’t enough.
Contact Lens Rules During an Infection
Stop wearing contact lenses immediately if you develop any eye infection symptoms. Lenses can trap bacteria against your eye and worsen the infection, and contaminated lenses can reinfect you after you’ve healed. Don’t put them back in until your symptoms have fully cleared, or until your eye doctor gives you the go-ahead.
If you were wearing disposable lenses when the infection started, throw that pair away. For reusable lenses, rub and rinse them thoroughly with fresh disinfecting solution before wearing them again. Clean your lens case the same way: rinse it with fresh solution (never water), dry it with a clean tissue, and store it upside down with the caps off. Never top off old solution with new solution, as mixing reduces the disinfecting power.
Preventing Spread to Others
Bacterial and viral conjunctivitis are both highly contagious. You remain contagious for as long as your eyes are tearing and producing discharge. Children who can’t reliably keep their hands clean or avoid close contact should stay home from school or daycare until symptoms resolve.
To limit spread: don’t share towels, washcloths, pillows, or eye makeup. Wash your hands frequently throughout the day. Avoid touching your face, and if you do touch your infected eye, wash immediately before touching anything else.
Signs You Need Immediate Care
Most eye infections are uncomfortable but not dangerous. However, certain symptoms warrant prompt medical attention. See a doctor if you experience significant eye pain (not just irritation), changes in your vision or blurriness, sensitivity to light that worsens, a feeling that something is stuck in your eye that won’t resolve, or if symptoms haven’t improved after several days of home care.
Any eye infection following an eye injury needs immediate evaluation, as infections of the cornea can threaten your vision. The same applies to newborns: eye infections in babies under a month old can become serious quickly, potentially spreading to the bloodstream or other organs. Newborns with red, swollen, or discharging eyes need same-day medical care.
