Researchers continue to investigate other transmission routes for the SARS-CoV-2 virus, including the eyes. Although it is much less common than the nose or mouth, eyes may be exposed to the transmission of the virus by touching the contaminated hand or by rubbing the eyes.
According to a review of 172 studies analyzing data collected from 16 countries, if healthcare workers and executives wore eye shields, there is significant protection against being infected by this virus and other respiratory pathogens. Additionally, wearing eye protection may make the transmission of COVID-19 about three times less likely.
Our tears are known to contain antibodies to help to detect and stop antigens such as bacteria and viruses. Findings show a potential pathway for the entry of infection with SARS-CoV-2 in human ocular tissue that could spark research into the importance of this route of spread.
Read the entire study and remember, keep your hands away from your face, wash hands frequently, and of course use PPE appropriately! Stay well, stay safe, and stay tuned!
