If Covid-19 can float in the air over particles and be there for up to 3 hours (1:50 minute), and if the virus could get into your system through eyes, nose or mouth (See Spread from contact with contaminated surfaces or objects section), then would not be better to use one of those suits to have full protection?
If no, why?
Suits and face mask like these ones
The mask, only covers your nose and mouth, if used properly. What about the eyes protection then?
