People who wear glasses could be up to three times less likely to be infected by coronavirus, a study from India has suggested.
One way the virus can enter the body is by people touching their eyes, nose or mouth after coming into contact with it.
However, researchers in India say people who wear glasses rub their eyes less and are therefore at less risk of contracting Covid-19.
In a non-peer reviewed study published on the website medRxiv, the researchers studied 304 people (223 male and 81 female) at a hospital in northern India over two weeks last summer. The patients were aged between 10 and 80 and had all reported Covid symptoms.
