COVID-19, caused by the SARS-CoV-2 virus, is primarily known for its respiratory effects, but it can also manifest with a variety of other symptoms throughout the body. Among the questions that frequently arise is whether the virus can impact eye health, specifically leading to conditions like bloodshot eyes or eye pain. While not as commonly discussed as fever or cough, eye-related symptoms are a recognized part of the COVID-19 symptom spectrum.
COVID-19 and Eye Redness
COVID-19 can cause bloodshot eyes, which is often a sign of conjunctivitis, also known as pink eye. This condition involves inflammation of the conjunctiva, the transparent membrane that covers the white part of your eye and the inside of your eyelids. The virus can directly infect this tissue, leading to the characteristic redness.
Conjunctivitis affects about 1% to 3% of people with COVID-19. While it is most commonly caused by other viruses, bacteria, allergens, or irritants, its occurrence alongside other COVID-19 symptoms suggests a link to the SARS-CoV-2 infection.
The redness can be accompanied by swelling and itchiness of the eyes. In some instances, conjunctivitis can even be the first or only symptom of COVID-19, though it more often appears alongside typical respiratory symptoms like fever or cough.
Other Eye Symptoms with COVID-19
Beyond redness, individuals with COVID-19 may experience other eye-related symptoms. Eye pain is a reported symptom, which can manifest as a dull ache and may be accompanied by sensitivity to light, known as photophobia. This pain can arise when the virus triggers inflammation in the eye or contributes to dry eye.
Other reported eye symptoms include watery eyes, a gritty sensation as if something is in the eye, and eye discharge, which can sometimes be yellow or green. Blurred vision is also noted, potentially occurring due to worsened dry eye or inflammation within the eye itself. These symptoms, while less common than respiratory issues, can still indicate a COVID-19 infection.
When to Seek Medical Attention for Eye Symptoms
If you experience eye symptoms, particularly in the context of suspected or confirmed COVID-19, it is advisable to consult a healthcare professional. Seek medical attention if you have severe eye pain, sudden changes in your vision, or if eye symptoms persist. These could indicate a viral infection or other underlying issues that require treatment.
It is also important to contact a doctor if eye symptoms are accompanied by a high fever, cough, or difficulty breathing, as these could signal a more severe COVID-19 illness. If you wear contact lenses and develop symptoms, it is particularly important to see your eye doctor promptly due to a higher risk of severe eye infections.
