Causes & Risk Factors
Several factors can contribute to Viral Conjunctivitis.
Viral conjunctivitis occurs when viruses infect the conjunctiva, the transparent membrane covering your eyeball and inner eyelid.
Viral conjunctivitis occurs when viruses infect the conjunctiva, the transparent membrane covering your eyeball and inner eyelid. The most common culprits belong to the adenovirus family, which also causes cold and flu symptoms. These viruses are incredibly hardy and can survive on surfaces for weeks, making them easy to pick up from contaminated objects like doorknobs, keyboards, towels, or makeup brushes.
The infection typically begins when you touch a contaminated surface and then rub your eyes, or when respiratory droplets from an infected person's cough or sneeze land directly in your eyes.
The infection typically begins when you touch a contaminated surface and then rub your eyes, or when respiratory droplets from an infected person's cough or sneeze land directly in your eyes. Adenoviruses have a particular affinity for the eye's mucous membranes, where they attach to cells and begin reproducing rapidly. Other viruses that can cause conjunctivitis include those responsible for the common cold, herpes simplex virus, and occasionally, more serious infections like Epstein-Barr virus.
Once the virus takes hold, your immune system responds by sending white blood cells to fight the infection, which causes the characteristic inflammation, redness, and increased blood flow to the affected area.
Once the virus takes hold, your immune system responds by sending white blood cells to fight the infection, which causes the characteristic inflammation, redness, and increased blood flow to the affected area. This immune response, while necessary to clear the infection, is what creates most of the uncomfortable symptoms you experience. The whole process from initial infection to symptom onset usually takes one to three days.
Risk Factors
- Close contact with infected individuals
- Attending school or daycare facilities
- Working in healthcare or childcare settings
- Sharing personal items like towels or makeup
- Having a weakened immune system
- Frequent touching of the face and eyes
- Poor hand hygiene practices
- Recent upper respiratory infection
- Wearing contact lenses
- Living in crowded conditions
Diagnosis
How healthcare professionals diagnose Viral Conjunctivitis:
- 1
Diagnosing viral conjunctivitis usually begins with your doctor examining your eyes and asking about your symptoms.
Diagnosing viral conjunctivitis usually begins with your doctor examining your eyes and asking about your symptoms. They'll look for telltale signs like redness, watery discharge, and swelling while checking whether one or both eyes are affected. Your doctor will also ask about recent illnesses, exposure to sick people, and whether anyone in your household or workplace has similar symptoms.

Most cases of viral conjunctivitis can be diagnosed through this visual examination alone, especially when classic symptoms are present.
Most cases of viral conjunctivitis can be diagnosed through this visual examination alone, especially when classic symptoms are present. However, if your doctor suspects bacterial conjunctivitis or another condition, they might take a small sample of eye discharge for laboratory testing. This helps determine whether bacteria are present and guides appropriate treatment decisions. Additional tests are rarely needed unless symptoms are severe, persistent, or accompanied by vision changes.

Your doctor will also rule out other conditions that can mimic viral conjunctivitis, such as allergic conjunctivitis, dry eye syndrome, or more serious infections.
Your doctor will also rule out other conditions that can mimic viral conjunctivitis, such as allergic conjunctivitis, dry eye syndrome, or more serious infections. They'll check your vision, examine the inside of your eyelids, and may use a special light to look for scratches on your cornea. If you wear contact lenses, they'll pay particular attention to signs of contact lens-related complications, which can sometimes occur alongside or instead of viral infections.
Complications
- Most people with viral conjunctivitis recover completely without any lasting effects on their vision or eye health.
- However, certain types of adenovirus can occasionally cause more persistent problems, particularly in adults.
- Some individuals develop small, round areas of inflammation on the cornea called subepithelial infiltrates, which can cause blurred vision and light sensitivity that may last for weeks or even months after the initial infection clears.
- Rare but more serious complications include corneal scarring, persistent dry eye, or secondary bacterial infections that develop when the eye's natural defenses are compromised.
- People with weakened immune systems may experience longer-lasting symptoms or more severe inflammation.
- If you notice worsening pain, significant vision changes, or symptoms that persist beyond two weeks, contact your doctor promptly for reevaluation and possible additional treatment.
Prevention
- Preventing viral conjunctivitis centers around excellent hand hygiene and avoiding contact with infected individuals when possible.
- Wash your hands frequently with soap and warm water for at least 20 seconds, especially after touching your face, using public surfaces, or being around sick people.
- If soap isn't available, use an alcohol-based hand sanitizer with at least 60% alcohol content.
- Avoid touching or rubbing your eyes, which can be challenging when they feel itchy or irritated.
- If you must touch your eyes, wash your hands thoroughly first.
- Never share personal items that come into contact with eyes or faces, including towels, pillowcases, eye makeup, contact lenses, or eye drops.
- Replace eye makeup and contact lenses after recovering from any eye infection to prevent reinfection.
- Clean and disinfect frequently touched surfaces like phones, keyboards, and doorknobs regularly, especially during outbreaks.
- If you're already infected, stay home from work or school until symptoms improve and you're no longer producing discharge.
- This typically means waiting 24-48 hours after symptoms begin to resolve.
- Cover your nose and mouth when coughing or sneezing, dispose of tissues immediately, and wash your hands afterward.
- Sleep on clean pillowcases and use fresh towels daily during the infection period.
The primary approach to treating viral conjunctivitis focuses on symptom relief and preventing spread to others, since antibiotics don't work against viruses.
The primary approach to treating viral conjunctivitis focuses on symptom relief and preventing spread to others, since antibiotics don't work against viruses. Your body's immune system will eventually clear the infection on its own, typically within seven to fourteen days. Cool, damp compresses applied to closed eyes for 10-15 minutes several times daily can significantly reduce discomfort and swelling. Use clean washcloths each time and avoid sharing them with others.
Over-the-counter artificial tears can help flush out irritants and provide moisture to dry, uncomfortable eyes.
Over-the-counter artificial tears can help flush out irritants and provide moisture to dry, uncomfortable eyes. Choose preservative-free drops if you'll be using them frequently, as preservatives can sometimes worsen irritation. Some people find relief with antihistamine eye drops, though these work best when allergies contribute to symptoms. Avoid eye drops that promise to "get the red out," as these can actually worsen redness when used repeatedly.
If symptoms are particularly severe or if you develop complications, your doctor might prescribe antiviral eye drops or ointments, though these are reserved for specific situations.
If symptoms are particularly severe or if you develop complications, your doctor might prescribe antiviral eye drops or ointments, though these are reserved for specific situations. Pain relievers like ibuprofen or acetaminophen can help with general discomfort and any accompanying headache. If you wear contact lenses, switch to glasses until your eyes are completely better and all discharge has stopped, then start with a fresh pair of contacts.
Recent research has explored the use of povidone-iodine solutions and certain antiviral compounds for severe cases, though these treatments are still being studied.

Most people recover completely without prescription medications, and the focus remains on supportive care and preventing the spread of infection to family members, coworkers, and classmates.
Living With Viral Conjunctivitis
Managing viral conjunctivitis day-to-day requires patience and consistent self-care while your body fights off the infection. Create a comfortable environment by dimming bright lights and using sunglasses when outdoors, as many people experience increased light sensitivity during the infection. Keep a supply of clean, cool washcloths handy for compresses, and consider using a humidifier if your eyes feel particularly dry.
