I don't wear glasses, but an issue I've noticed while wearing N95 masks is that my eyes start crying. I've thought it could be caused by the warm breath being directed upward toward my eyes.
That sounds like you have a fit issue. At least that's my guess, since I can't relate. I've worn Auras and glasses to the cinema many times.
I didn’t realize this happened to me until reading this comment. I think for me it was a combination of air flow redirection and just pinching from the metal bits high enough on my nose that maybe there’s some squeezing the tear ducts going on?
