I wear safety glasses since I saw a South Korean doctor who is considered to be “thee authority” in S.K. on SARS CoV-2 / Covid-19 suggest that it may help because they have found virus in the eyes and tears of patients and airborne droplets can easily find their way there. The video had subtitles and was easy to follow. Actually, there are at least two of these videos with him and both were very interesting. What I liked about him is that he did not seem to be working toward any type of political agenda, just straight facts about the virus and what they are doing in SK to deal with it. It was kind of refreshing listening to his straight forward answers!
Here is a link to one of the videos featuring Professor Woo-Joo Kim. You never get the impression that he is trying to be evasive with his answers, just facts based on his experience with Covid-19. Somewhat similar to Dr. Seheult of the MedCram series, but less technical than Dr. Seheult.
As far as the safety glasses, it seems like a small measure to try and reduce the risk of infection. Yes, even though I believe in the science behind melatonin for Covid-19, at this point I would prefer not to be infected if possible, so I do wear an N-95 mask and safety glasses that wrap around.
