> Why are people with glasses still wearing masks?

Even a crappy mask can still give others some protection from your coughs & sneezes. Plus, I've noticed it can help remind people that you wish to keep some distance (whether it's for their benefit or for yours).

As an aside, I finally tried a good fitting N95 (3M) and tried it outside today for an hour walk in 35-deg-F weather. First time I've never had my glasses fog; not even a bit.

Yeah, don't really need a mask outside if you avoid crowds, but the air quality was less than perfect here today.
