It’s well-established that the virus that causes COVID-19 can be transmitted through the mucous membranes of the eyes. This is the reason that health-care workers’ protective equipment includes face shields and goggles.
What’s less clear is whether ordinary eyeglasses might keep the coronavirus at bay. An observational study released Wednesday provides new insight into that question.
Researchers surveyed 276 patients hospitalized for COVID-19 in Suizhou, China, and determined which of them wore eyeglasses for at least eight hours a day.
