People who wear glasses are two to three times less likely to be infected with COVID-19, according to a new study.
Indian researchers studied 304 patients whose eyeglass wear habits were examined through a questionnaire and compared to existing studies of the general population, according to a study published in medRxiv, which is not peer reviewed.
“This current study has shown that the risk of COVID is two to three times lower in the population wearing glasses than in the population not wearing glasses,” Amit Kumar Saxena said in the results, the UK Mirror reported.
“The protective role of glasses was statistically significant, if they were used for (a) a long time of the day,” he added. “Touching and rubbing the eyes with contaminated hands can be a major route of infection.”
The researchers said people touch their faces an average of 23 times an hour and their eyes an average of three times an hour.
“Touching your nose and mouth is greatly reduced when wearing a face mask correctly. But wearing a face mask does not protect the eyes, ”says the study.
“The nasolacrimal duct may be a route of virus transmission from the conjunctival sac to the nasopharynx,” according to the study.
According to the authors, a total of 58 patients wore glasses continuously during the day and during outdoor activities.
