Daily wearers of eyeglasses may be less susceptible to COVID-19

Posted on

A new report in JAMA Ophthalmology sought to determine the association between wearing glasses daily and the susceptibility of becoming infected with COVID-19.

In this cohort study, a total of 276 patients with COVID-19 in Suizhou Zengdu Hospital, Suizhou, China were included. A total of 15 patients (5.8%) wore glasses for more than 8 hours per day and all had myopia.

According to a previous study, 31.5% of people in Hubei province have myopia, a proportion much higher than those with myopia who had COVID-19 in this cohort.

The authors concluded that the smaller proportion of patients with myopia infected with COVID-19 compared to the general proportion of patients with myopia may suggest that daily wearers of eyeglasses may be less susceptible to infection.
