Can you contract coronavirus through your eyes?
When a contaminated surface, such as unwashed hand, comes into contact with the eye, coronaviruses can transfer onto the surface of the eye.
COVID-19 could cause itchy eyes, sore eyes and sensitivity to light within your body. Although doctors and scientists are still researching and investigating the effects Coronavirus can have on our eyes, some interesting studies have highlighted common eye issues found amongst COVID-19 patients.
These symptoms include burning eyes, red eyes, sore eyes, puffy eyes, and watery eyes. However, it is important to note that while these symptoms were present during infection of COVID-19, they may have been caused by something else.
According to a study by the American Academy of Ophthalmology, conjunctivitis has been found in 1% - 3% of adults with a positive case of COVID-19. This is a common eye infection, which causes inflammation and redness, hence why many know this as ‘pink eye’. Whether you are COVID positive or not, a case of viral conjunctivitis should be taken seriously and make efforts to prevent this from spreading.
Symptoms of viral conjunctivitis include:
Since COVID can spread through the eyes, many healthcare professionals have advised wearing eye protection like goggles.
In some studies of COVID-19 cases, cases of increased eye secretion have been identified. This could be a possibly COVID-19 symptom. Most people have described this as having runny eyes, and others have said their eyes had felt ‘goopy’ or ‘gooey’, describing the eye discharge they are experiencing more frequently with their case of COVID-19.
However, it is important to note that this is not always a symptom of COVID-19 and can be very normal. Eye discharge plays an integral part in keeping our eyes healthy, so this isn’t always something to be concerned about. If you have excessive eye discharge or change in colour or consistency, this could also be a sign of conjunctivitis and many other eye infections. It is essential to speak to a health care professional if you are unsure and require treatment. Your optician can often provide eye drops or other treatments for eye infections.
Eye swelling is a common symptom of conjunctivitis and could also be a sign of chemosis. A very small study of 38 COVID-19 patients found that chemosis was also present. This is described as the swelling of the conjunctiva, which is the thin membrane covering the front of your eye and the insides of the eyelids.
Other symptoms of chemosis include:
As coronavirus research is ongoing, doctors continue to learn about the link between this and eye conditions, so it is still early to assume there is a connection between Coronavirus and chemosis.
The same study found some positive coronavirus patients experiencing epiphora, also known as watery eyes. However, this has not been confirmed as a conclusive symptom of Coronavirus.
Those who have epiphora will experience an overflow of tears from the eyes along with other symptoms, including:
This can be caused by a range of conditions, including:
You can ease these symptoms with the use of antihistamines, cool compresses, changing contact lenses and taking a break from staring at screens.
Eye twitching has not been identified as a symptom of COVID-19. After 12 studies on the symptoms of COVID-19, however, COVID-19 has been shown to cause neurological symptoms in some patients, such as facial spasms, which could cause eye twitching.
An eye twitch is an uncontrollable spasm of the eyelid. This can occur for several reasons, such as allergies, caffeine consumption, dry eyes, stress. Often this will go away on its own. If this does persist, you should see an eye doctor.
Although some studies have encountered COVID-positive patients with eye problems, these are not necessarily directly linked to one another. It could just be a coincidence that eye issues have been reported simultaneously as a patient having a positive case of COVID-19.
If you have been experiencing any eye conditions mentioned and require treatment, it is essential you seek advice and guidance from your eye health care provider.
