I don’t wear glasses full time, just sunglasses and reading glasses, but they’re really hard to make compatible with masks. Fogging up sounds like an inconvenience but you basically can’t see within seconds. I wonder if a lot of people opted for contacts or lasik during this period to help compensate. Regardless, yes, masks on flights just make sense. It’s a huge number of strangers in a very close space and not something you need to do every day. You’re not exercising or socializing or moving about in public so why not just mask up and sit tight.
