A new study outside India has found that people who wear glasses are three times less likely to get the virus.
Researchers suggest they are less likely to touch their eyes – which could be an important route of infection.
A previous study in China found that only 5% of hospitalized people from Kovid wore glasses, while about 30% wore glasses.
The study was conducted last summer in Kanpur rural district. This includes 304 patients aged 10 to 80 years.
All of them experienced coronavirus symptoms and up to 60 were considered long-term glass wearers, according to the report.
The authors in the study noted that Covid-19 infections through the eyes are “extremely rare”, but they said that drops from the virus could easily pass through the eyes to someone’s nose or mouth.
