Does Wearing Glasses Protect You From Coronavirus?
And Dr. Maragakis noted that any number of factors could confound the data, and it may be that wearing glasses is simply associated with another variable that affects risk for Covid-19. For example, it could be that people who wear glasses tend to be older, and more careful and more likely to stay home during a viral outbreak, than those who do not wear glasses. Or perhaps people who can afford glasses are less likely to contract the virus for other reasons, like having the means to live in less crowded spaces.
“It’s one study,” Dr. Maragakis said. “It does have some biological plausibility, given that in health care facilities, we use eye protection,” such as face shields or goggles. “But what remains to be investigated is whether eye protection in a public setting would add any protection over and above masks and physical distancing. I think it’s still unclear.”
Health care workers wear protective equipment over their eyes to protect them from droplets that can fly from coughs and sneezes, as well as aerosolized particles that form when patients undergo medical procedures, such as intubation. But for the vast majority of people, that extra level of protection probably isn’t needed if a person is wearing a mask and keeping physical distance in public spaces. There’s also the possibility of introducing risk by wearing glasses — some people might touch their faces more when they put on glasses, rather than less, noted Dr. Maragakis.
That said, more study is needed to see ...
