A new study suggests that wearing glasses daily may reduce the risk of contraction of novel coronaviruses.
Researchers in China found that COVID-19 patients were five times less likely to frame than the general population.
The team at another affiliated hospital at Nanchang University says that they believe that ACE-2 receptors, which the virus latch onto to enter and infect human cells, can be found in the eye.
The findings also provide more evidence as to why health care workers should wear eye protection and why preventive measures require more attention such as frequently washing their hands and avoiding touching their faces.
A new study found that 5.8% of the approximately 300 coronavirus patients wore glasses eight hours a day for myopia, compared to 31.5% of people in the province of Hubei. Picture: A man wears an American and Puerto Rico flag mask in New York City in September 2020
This indicates that people wearing frames are nearly five times less likely to be diagnosed with COVID-19 than the general population. Image: In July 2009, a health worker visits a patient at the COVID-19 unit at United Memorial Medical Center in Houston, Texas.
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 proximity and 14 cases of foresight.
None of those diagnosed with the virus wore contact lenses or had to undergo refractive surgery to correct their vision.
A total of 16 patients, all proximal, were long-term wearers, defined as 5.8 percent wearing glasses for more than eight hours a day.
For the general population, researchers focused on studies of students between the ages of seven and 22 in Hubei Province decades ago, 31.5 percent of whom wore glasses for proximity.
At the time of publication, those students will be aged between 42 and 57, close to the average age of 31 for COVID-19 patients.
This means that the general population is 5.4 times more likely to wear glasses than those suffering from coronovirus.
‘Our main finding was that patients with COVID-19 who wear glasses for an extended period of time every day were relatively uncommon, which may be preliminary evidence that daily glasses wearers are susceptible to COVID-19,’ The authors wrote.
Researchers hypothesize that the frame prevents or discourages wearers from touching their eyes, thus avoiding transferring the virus from hands to eyes.
Studies have recently found that the eyes produce ACE-2, making organs the main target of the virus.
The coronavirus has been found not only on the surface of the eyes, but also within the tears, which will transfer the pathogen.
This may indicate that up to 12 percent of patients with COVID-19 have so-called ‘ocular manifestations’ such as redness and swelling.
The authors wrote, “Therefore, SARS-COV-2 is considered an important channel for the eyes to enter the human body.”
‘For daily wearers who wear glasses, who usually wear glasses on social occasions, wearing glasses can become a protective factor, reducing the risk of virus transfer to the eye and prolonged daily wear of glasses. , Which are rarely infected with COVID-19. ‘
An Associate Professor of Medicine and Epidemiology at Johns Hopkins University School of Medicine, Drs. Lisa Maragakis said in an invited comment that people should not wear glasses when needed.
‘However it is tempting to conclude from this study that everyone should wear glasses, goggles or a face shield in public, from an epidemiological perspective, to protect their eyes and themselves from COVID-19 “We should be careful to avoid making a working relationship with a single observational study,” she wrote.
