Two relatively small-scale studies,
one from India and
the other from China, suggest that glasses-wearers are significantly less likely to contract Covid - 2-3x less (the India study) or up to 5x less (the China study). Possible reasons include people who wear glasses touching their eyes less, compared to non-glasses wearers, or possibly glasses providing a protective shield against aerosols, like goggles or face shields.
So I just thought that was interesting! These things have been such a gigantic pain to cope with while wearing masks; it's nice to know they might actually be a little bit helpful as well.
