While wearing glasses, they fog up all the time when the mask is on.
What I need is one that has air vents at the bottom of them.
I have the same experience. The glasses actually fog up each time I exhale. I've ordered some cloth masks online which should be here anytime. I am anxious to see if they work any better than the paper ones do.
I put the mask on right before going in to the store and take it off immediately after leaving the store. I figure once I am out in the open air, folks can stay 6' away more easily.
In the beginning, I resisted wearing a mask. I made every excuse not to that I could think of. Once I realized it was more for the protection of other folks than it was for mine, I started being more diligent.
