Some people swear by folding the top edge of the mask under, so there’s a tiny bit that’s doubled there. That didn’t work for me, but we all have different faces.
There have been some threads on mask recommendations. I’ll see if I can link one.
This one is fairly recent and has some links for good masks. I think there have been some on mask fitting and wearing with glasses as well, which is more your question, I guess. I’ll see if I can find one of those.
