People who wear glasses are FIVE TIMES less likely to be diagnosed with COVID-19 than the general public
Wearing glasses every day may reduce your risk of contracting the new coronavirus, a new study suggests.
Researchers from China found that COVID-19 patients were five times less likely to get frames than the general population.
The team, from Nanchang University’s The Second Affiliated Hospital, say they believe this is because ACE-2 receptors, which the virus clings to to enter and infect human cells, are found in the eyes.
The findings also provide more evidence for why health professionals should wear eye protection and why more attention should be paid to preventive measures, such as washing their hands often and avoiding touching their face.
A new study found that 5.8% of the nearly 300 coronavirus patients wore glasses for myopia for eight hours a day, compared to 31.5% of people in Hubei province. Pictured: A man wearing an American and Puerto Rico flag mask in New York City, September 2020

For the study, published in JAMA Ophthalmology, the team looked at 276 patients diagnosed with COVID-19 between January 27 and March 13.
Thirty patients wore glasses (10.9 percent), including 16 cases of myopia and 14 cases of hyperopia.
None of those diagnosed with the virus wore contact lenses or had refractive surgery to correct their vision.
A total of 16 patients, all short-sighted, were long-term wearers, defined as wearing glasses for more than eight hours a day, accounting for 5.8 percent.
For the general population, the researchers looked decades ago at study of students between the ages of seven and 22 in Hubei province, 31.5 percent of whom wore glasses for myopia.
At the time of publication, those students would be between 42 and 57 years old, close to the mean age of 31 for the COVID-19 patients.
This means that the general population is 5.4 times more likely to wear glasses daily than those diagnosed with the coronavirus.
‘Our main finding was that patients with COVID-19 who wore glasses every day for an extended period of time were relatively uncommon, which could be preliminary evidence that everyday spectacle wearers are less prone to COVID-19,’ the authors wrote.
The researchers hypothesize that frames “deter or discourage wearers from touching their eyes, thus preventing the virus from transferring from the hands to the eyes.”
Studies have recently shown that the eyes produce ACE-2, which makes the organs a prime target for the virus.
Coronavirus has been found not only on the surface of the eyes, but also in tears, which are said to transmit the pathogen.
This may explain why up to 12 percent of patients with COVID-19 have so-called ‘ocular manifestations’ such as redness and swelling.
“Therefore, the eyes are considered an important channel for SARS-CoV-2 to enter the human body,” the authors wrote.
For everyday spectacle wearers, who usually wear spectacles at social occasions, wearing spectacles can become a protective factor, reducing the risk of virus transmission to the eyes and making long-term spectacle wearers rarely contaminated with COVID-19. ‘
In an invited comment, Dr. Lisa Maragakis, associate professor of medicine and epidemiology at Johns Hopkins University School of Medicine, said people shouldn’t wear glasses if they don’t need them.
While it is tempting to conclude from this study that everyone in public should wear glasses, goggles, or a face shield to protect their eyes and themselves from COVID-19, from an epidemiological point of view, we must be careful not to Causal relationship cannot be deduced. from a single observational study, ‘she wrote.
