plus they couldn't find a mask that works with their glasses

Most KN95s and all N95s I have tried fog my glasses. But ProGear N95s don't, that's the kind that I prefer. Once you put it on, you can press the metal nose band to fit it to your exact nose shape

But I've also read enough anecdotal reports from people who use them and still got sick with covid. Who knows if they were properly applied,

Maybe it's important to get one with a good spray. The Betadine iota carrageenan spray is very good, with respect to diffusion. It also doesn't require shaking or spraying beforehand to get a full spray.

Some Covixyl bottles don't diffuse the spray well, and it's very noticeable

but I doubt these sprays alone will do much if your exposure levels are high.

And if there's enough COVID in the air, you can get COVID in your eyes, not just your nose. Wearing Stoggles helps if someone coughs in your direction, but not if there's just lots of COVID in the air
