but it's really going to grate on me if I have to wear community glasses.

The glasses are sent away and sanitized and repackaged. They come sealed in individual plastic bags. Completely safe and sanitized. No cootie worries.
If you have ever had a medical procedure including a pap smear, or been to a dentist, their stuff is clean and gets crammed in much more disgusting places than a pair of sanitized glasses will ever go.
For what it is worth, I do not like Science Fiction - it is never a book choice of mine - and yet I loved the movie.
