New research suggests that a common accessory that is already used by millions of people may make the user three times less likely to get COVID-19.
Although facial masks have reduced the risk of contracting or spreading COVID-19 through the mouth and nose, little research has been done on how to prevent the virus from entering people’s eyes.
However, a recent study found that people who wear glasses at least 8 hours a day are two to three times less likely to get COVID-19 than people who don’t.
The same level of protection applies to people who wear sunglasses whenever they are outdoors.
The glasses provide some physical protection against the virus that spreads through airborne saliva or mucus, but the real reason why spectacle wearers are not so susceptible to contracting COVID-19 is that the glasses prevent people from touching and rubbing the eyes.
The study’s principal investigator is Amit Kumar Saxena, from India. To read the full study, go to medrxiv.org.
