Wearing glasses can help reduce the risk of contracting SARS-CoV-2
According to British scientists, people who wear glasses have the ability to reduce the risk of infection by 15% SARS-CoV-2 compared with those who did not.
The Virus Watch study called for 58,670 volunteers in England and Wales to participate. Of these, 31,749 people were invited to respond to a monthly survey on the use of glasses and contact lenses. As a result, 19,166 people responded to this questionnaire, the average age of the study was 63.
Participants answered questionnaires about frequency of use, purpose, and whether or not to wear it glasses or contact lenses, whether used with a mask or not. From June 2020, participants weekly update their status related to Covid-19.
The rate of SARS-CoV-2 infection in the glasses-using group was 15% lower than in those who never wore glasses
Results 13,681 out of 19,166 respondents to the survey said that they wear glasses, accounting for 71.3%. A multivariable logistic regression model showed that the prevalence of SARS-CoV-2 infection in the glasses-using group was 15% lower than in those who never wore glasses. Results published in the journal Medrxiv on 4.4.
Survey shows no protective effect on wearer lens.
According to scientists, there are two routes of infection SARS-CoV-2 through the eyes. The first route is infection by conjunctival cells containing ACE2 receptors. Several studies have detected SARS-CoV-2 in the tear film, conjunctiva, and conjunctival sac in 1-12% of patients. Covid-19 is present in the eye.
The second route of infection is through the lacrimal gland, from where the pathogen travels to the nose within minutes and down the throat.
Therefore, according to researchers, wearing glasses to protect eyes is one of the measures to prevent the risk of infection with SARS-CoV-2 virus in the community.
