It's quite possible that infection is occurring via the eyes, this could explain why masks protect others but not the wearer.

- petertodd 6y agoWait, do you have a source for the statement that "masks protect others but not the wearer"? Because I've seen that claim a lot. But never actually seen a scientific study making that claim.
- aeternum 6y agoIsn't this very study an example of one that shows that masks do not offer significant protection for the wearer? Whether or not masks protect others seems much harder to isolate but there does seem to be lower R^2 values for countries and areas with more normalized mask wearing. Perhaps it is just a correlation (just seeing masks reminds people of the risk and they modify their behavior).
