Yes, pink eye (conjunctivitis) is a recognized symptom of COVID-19, though it’s not one of the most common ones. The World Health Organization lists “red or irritated eyes” among the less common symptoms of the disease. A meta-analysis published in the Canadian Journal of Ophthalmology found that roughly 11% of COVID-19 patients develop conjunctivitis, putting it well behind fever, cough, and fatigue but common enough to be worth knowing about.
What COVID-Related Pink Eye Looks and Feels Like
COVID-19 conjunctivitis typically produces watery discharge rather than the thick, yellow-green pus you’d see with a bacterial eye infection. The most frequently reported signs include redness of the white of the eye, mild swelling of the eyelids, a watery or clear discharge, light sensitivity, and a gritty or burning sensation. Some patients also develop swollen lymph nodes near the jaw or in front of the ear, which is a hallmark of viral conjunctivitis in general.
In more severe COVID cases, particularly among patients in intensive care, a condition called chemosis (significant swelling of the clear membrane covering the white of the eye) becomes more prominent. One study of 309 hospitalized COVID patients with eye involvement found that 58% had chemosis. For most people with milder infections, though, the eye symptoms stay relatively mild and resolve on their own.
When Eye Symptoms Appear
The timing varies quite a bit. In some cases, pink eye is the very first sign of a COVID infection, appearing a day or two before fever, cough, or other respiratory symptoms kick in. A case report from Argentina documented conjunctivitis as the initial symptom, with other systemic symptoms following within hours. In other patients, eye redness and irritation show up later in the course of the illness, after the classic symptoms are already present.
A small number of people develop conjunctivitis as their only COVID symptom. A study from Italy followed five patients diagnosed with viral conjunctivitis who tested positive for SARS-CoV-2. Over a two-week quarantine period, none of them developed fever, breathing difficulties, or any other symptoms. This is uncommon, but it means pink eye alone doesn’t rule out a COVID infection if you’ve had a known exposure.
How It Differs From Other Types of Pink Eye
Not all pink eye points to COVID. Bacterial conjunctivitis produces thicker, pus-like discharge and often crusts the eyelids shut overnight. Allergic conjunctivitis is triggered by pollen, dust, or pet dander and tends to cause intense itching in both eyes, often alongside sneezing and a runny nose. COVID-related conjunctivitis leans toward watery discharge, mild irritation, and redness, and it usually affects one eye initially before sometimes spreading to both.
The biggest clue is context. If your pink eye appears alongside other COVID symptoms like fever, sore throat, congestion, fatigue, or loss of taste and smell, it’s reasonable to suspect a COVID connection. If it shows up during allergy season with no other symptoms, allergies are a far more likely explanation.
Why the Virus Can Affect Your Eyes
SARS-CoV-2 enters cells by latching onto a specific protein on their surface called ACE2. Research published in the journal Eye found that human conjunctival cells do express this protein, though at lower levels than lung tissue. The cornea (the clear front surface of the eye) actually shows higher potential for infection than the conjunctiva. This helps explain why eye symptoms occur in a meaningful minority of patients but remain far less common than respiratory symptoms.
The virus has also been detected in tears and conjunctival secretions, though at low rates. One study found SARS-CoV-2 in about 7% of conjunctival swabs and 4% of tear samples from infected patients. Positivity rates were higher among patients with severe disease. This means touching your eyes and then touching surfaces or other people could theoretically spread the virus, even if the risk is relatively low compared to respiratory droplets.
Pink Eye and COVID in Children
Conjunctivitis is the most common eye-related finding in children with COVID-19, and its frequency varies widely across studies, from less than 1% to nearly 32% depending on the population studied. Early reports from Wuhan found conjunctival discharge in over half of pediatric cases examined.
Where pink eye becomes especially notable in children is in multisystem inflammatory syndrome in children (MIS-C), a rare but serious inflammatory condition that can follow a COVID infection. In a large retrospective study of 570 children with MIS-C, nearly half (48.4%) had conjunctivitis at the time of diagnosis. A smaller New York study found 11 out of 17 children with MIS-C presented with conjunctivitis. So in a child recovering from COVID, new-onset pink eye alongside fever, rash, or abdominal pain warrants prompt medical attention.
Newer Variants and Eye Symptoms
COVID symptoms have remained broadly consistent across variants. The JN.1 variant, which became dominant in late 2023 and into 2024, lists conjunctivitis among its possible symptoms alongside sore throat, fever, congestion, cough, and fatigue. There’s no strong evidence that any particular variant causes significantly more or fewer eye symptoms than others. The 11% prevalence figure from the meta-analysis reflects data gathered across multiple waves and strains.
If you develop pink eye with no obvious allergic trigger, especially alongside respiratory symptoms or after a known COVID exposure, a COVID test is a reasonable step. For most people, COVID-related conjunctivitis resolves within one to two weeks without specific eye treatment, following the same general timeline as other mild COVID symptoms.
