Eyeglasses Reduce Risk of COVID-19 Infection.

Lehrer, Steven; Rheinstein, Peter

BACKGROUND/AIM A study of patients in the Hubei Province, China, at the beginning of the pandemic demonstrated that among a group of 276 patients admitted to a hospital with laboratory-confirmed COVID-19, the proportion of patients who said they routinely wore eyeglasses more than 8 hours per day was lower than in the general population. Therefore, wearing eyeglasses more than 8 hours per day may be protective against SARS-CoV-2 infection, possibly because eyeglasses are a barrier that reduces the frequency with which people touch their eyes. The aim of the study was to determine if eyeglasses protect from COVID-19 infection. MATERIALS AND METHODS We used UK Biobank (UKB) data to corroborate findings of the Hubei study in the UK population. RESULTS Eyewear was associated with a reduced risk of infection, odds ratio (OR)=0.77. The effects of sex, age, and eyewear were independent and significant at the 95% level. Men are 1.24-times more likely to be infected than women; subjects' risk of infection is less (0.95) for every year of age. CONCLUSION The public at large may profit from wearing glasses, as well as wearing face masks and practicing social distancing.
