“Challenging” study People who wear glasses are less likely to get coronavirus

The proportion of patients with Covid-19 who wear glasses daily is much lower than the percentage of diopters in the general population, which probably suggests that for some reason those who wear glasses are at lower risk of developing coronavirus. This is the rather unexpected conclusion of a new small study by Chinese scientists.

The researchers, who published the study in the American Journal of Ophthalmology, analyzed data on 276 patients with Covid-19 and a mean age of 51 years in a hospital in Hubei Province. They found that only 6% of patients wore myopia glasses (not contact lenses), while the percentage of people with myopia in the province reached 31.5% in an earlier study (according to the World Health Organization, myopia is at least 27% internationally) .

“Lisa Maragaki, an associate professor of epidemiology at Johns Hopkins University School of Medicine, spoke of a” challenging study that raises the possibility that eye protection in the general population may provide some protection against Covid-19. ”

He added, however, that it was too early to recommend that everyone wear glasses or plastic eye masks, as the Chinese study was performed on a small sample of patients in a single hospital and found only a correlation and not a cause-and-effect relationship. Therefore, he said, the issue needs further study to confirm whether those who wear glasses or masks, especially in public places, are less at risk of coronavirus.

So far, the recommendations of health authorities around the world focus on the triptych: masks-keeping distance-hand washing. Touching the eyes with infected hands probably allows the virus to enter the body, as the eyes have cellular receptors that allow the new coronavirus to attach to them.
