Recently, I asked a nurse how she could wear a mask all day during work and still wear her glasses. I was interested as this is my biggest complaint with masks as I, too, wear glasses. She gave me a couple to try. The masks were fabulous!! So I now have a new box of my own, and will order again. They work incredibly well. Glasses will still steam up if there is a large temperature gradient, but otherwise, these are the best masks I have found to use.
