Those who wear glasses are up to three times less likely to be infected by coronavirus, according to a new study published by the British newspaper Independent.
According to the scientific community, one way in which the virus can enter the body is through touch in specific areas of the face: that is, when we touch the eyes, nose or mouth. However, researchers in India claim that those who wear glasses rub their eyes less and therefore have a lower risk of developing Covid-19.
In their study, published on the medRxiv website, researchers examined 304 people (223 men and 81 women) in a hospital in northern India for two weeks to monitor their health last summer.
The patients ranged in age from 10 to 80 years and had all reported symptoms of Covid disease. Of the participants, 19% said they wore glasses most of the day.
Do glasses protect against coronavirus?
The researchers found that participants touched their faces up to 23 times an hour, on average, and their eyes, three times an hour, on average.
Indian scientists have concluded that, in the category of diopters, the risk of contracting the disease was two to three times lower. “Touching and rubbing the eyes with infected hands can be a major route of infection,” they said in a report.
“Long-term use of glasses can prevent repeated contact and rubbing of the eyes,” they add. It is worth noting that doctors have already advised people wearing contact lenses to prefer eyeglasses to avoid the possible transmission of coronavirus through their hands to the eyes.
