COVID-19 can cause itchy eyes. This is likely to be due to conjunctivitis, the most common eye condition that’s reported with COVID-19.

Conjunctivitis is an inflammation of the conjunctiva, which is the clear membrane that lines the whites of your eyes and the insides of your eyelids. Eye irritation, which can include itching or burning, is a potential symptom of conjunctivitis.
