Viral conjunctivitis has no cure and no effective antiviral treatment for the vast majority of cases. It resolves on its own, typically within a few days to two weeks. Treatment focuses entirely on relieving symptoms while your body fights off the infection, and on preventing spread to other people or your other eye.
Why Antibiotics Won’t Help
One of the most important things to understand is that antibiotic eye drops do nothing for viral conjunctivitis. The American Academy of Ophthalmology specifically warns against the indiscriminate use of topical antibiotics, since viral conjunctivitis will not respond to them. Despite this, many people leave a doctor’s visit with an antibiotic prescription “just in case.” If your symptoms clearly point to a viral cause (watery rather than thick discharge, no pus, and possibly a swollen lymph node in front of your ear), antibiotics are a waste of money and can contribute to resistance.
Symptom Relief That Actually Works
The CDC recommends two main tools for managing discomfort: cold compresses and artificial tears. Neither shortens the infection, but both can meaningfully reduce how miserable you feel day to day.
Cold compresses: A clean washcloth soaked in cool water and placed over your closed eyelids for 5 to 10 minutes can ease the burning, swelling, and gritty sensation that viral conjunctivitis causes. Use a fresh cloth each time, and don’t share it. If only one eye is affected, use separate cloths for each eye to avoid spreading the virus.
Artificial tears: Preservative-free artificial tears (available over the counter) help wash away discharge and relieve the dryness and irritation. You can use them several times throughout the day as needed. Avoid drops labeled “get the red out,” which work by constricting blood vessels and can cause rebound redness without treating the underlying inflammation.
If your eyes feel sticky in the morning, gently wipe crusty discharge from your lashes with a warm, damp cloth before opening your eyelids. This is often the most uncomfortable moment of the day, and a minute of warm soaking makes it much easier.
How to Tell It’s Viral, Not Bacterial
The type of discharge is the clearest clue. Viral conjunctivitis produces a thin, watery or slightly stringy discharge and profuse tearing. You may also notice a burning or gritty sensation and some light sensitivity. It often starts in one eye and spreads to the other within a day or two, and many people have a cold or upper respiratory infection at the same time.
Bacterial conjunctivitis, by contrast, produces thick, yellow or green pus that collects at the corners of the eye and along the lid margin. Your eye may be completely stuck shut in the morning. A swollen, tender lymph node just in front of your ear is common with viral infections and usually absent in bacterial ones. Allergic conjunctivitis shares the watery discharge of viral, but itching is its hallmark, and it almost always affects both eyes from the start.
How Long It Lasts and When You’re Contagious
Most cases improve within one to two weeks. The infection remains contagious for as long as your eyes are tearing and producing discharge. For adenovirus, the most common culprit, the contagious window is typically 10 to 14 days from the onset of symptoms.
Interestingly, current guidelines from the American Academy of Pediatrics do not recommend routinely excluding children with conjunctivitis from school or daycare, as long as the child has no fever and no behavioral changes. The emphasis is on careful hand hygiene and minimizing close contact rather than keeping kids home. That said, individual schools and workplaces may have their own policies, so it’s worth checking.
Stopping the Spread
Adenoviruses are remarkably hardy. They resist many common household disinfectants and can survive on surfaces for hours. To clean countertops, doorknobs, and shared items like phones or remote controls, use an EPA-registered disinfectant effective against adenovirus (the EPA maintains a list called “List G,” and products effective against norovirus also work against adenovirus). Regular soap and water won’t reliably kill the virus on surfaces.
Beyond cleaning, the most effective steps are behavioral:
- Wash your hands frequently, especially after touching your eyes or face.
- Use a separate towel and pillowcase from the rest of your household.
- Avoid touching your eyes as much as possible, and if you do, wash your hands immediately after.
- Don’t share eye drops, makeup, or contact lenses. Discard any eye makeup you used while infected.
- Stay out of swimming pools until symptoms resolve.
If only one eye is infected, be especially careful not to transfer the virus to the other. This means using a different tissue or cloth for each eye and washing hands between touching them.
When Symptoms Need Medical Attention
Most viral conjunctivitis is uncomfortable but harmless. Certain symptoms, however, signal something more serious, such as a corneal ulcer or involvement of deeper eye structures. Seek care promptly if you notice severe light sensitivity, blurred or decreased vision, intense eye pain (beyond the typical gritty irritation), a feeling of something stuck in your eye that won’t resolve, a large and increasing amount of discharge, or symptoms that keep getting worse after the first week rather than slowly improving.
Contact lens wearers should stop wearing their lenses immediately at the first sign of pink eye and see a provider, since lenses increase the risk of corneal complications.
Severe Cases and Corneal Involvement
A small percentage of viral conjunctivitis cases, particularly those caused by specific adenovirus strains (a condition called epidemic keratoconjunctivitis), can affect the cornea and cause prolonged blurry vision or light sensitivity even after the redness clears. In these more severe cases, an ophthalmologist may consider a topical antiviral gel, which limited studies suggest can shorten the course and reduce corneal complications. This is not a routine treatment and is reserved for cases where the cornea is involved. Steroid eye drops are sometimes used for corneal inflammation as well, but only under close monitoring by an eye specialist, since steroids can worsen certain infections and raise eye pressure.
For the vast majority of people, though, viral conjunctivitis is a waiting game: keep your eyes comfortable, keep your hands clean, and give it two weeks.
