Daily wearers of eyeglasses might have  lower chance of getting infected with COVID-19 than other people,  a new report suggests.

The study enrolled all inpatients with COVID-19 in Suizhou Zengdu Hospital in Suizhou, China, from Jan. 27 to March 13. Of the 276 patients, 16 wore glasses for more than eight hours a day. Of those 16, all had myopia.

Based on a previous study, the proportion of people with myopia in Hubei province was 31.5 percent. That was significantly higher than the proportion who had myopia in this sample.

The researchers concluded: “Our study found that the proportion of inpatients with COVID-19 who wear eyeglasses for extended daily periods was lower than that of the general population, suggesting that daily wear of eyeglasses is associated with less susceptibility to COVID-19 infection. These findings suggest that the eye may be an important infection route for COVID-19, and more attention should be paid to preventive measures such as frequent hand washing and avoiding touching the eyes.”

The report was published online on Sept. 16 by JAMA Ophthalmology. The researchers noted that the work had several limitations, including the fact that it was a single-center study with a small sample size.
