The COVID-19 pandemic

Not if it fits properly, along your nose and cheeks. With the proper fit, the humid air (when exhaling) will exit on the sides or bottom rather than the top. My latest (fabric) mask has far less fogging issues than what I was using before.

It definitely depends on the mask, but most, including all I have tried have a lot of leakage up the top of the mask.

Tips:

1) Pull the mask high up on your nose.  Place the glasses on top of the mask and not above the mask.  No more fogging.

2) Take a 1/2 kleenex and fold into a thin strip.  Place this against your nose/cheeks at the metal clip in the mask.  No more fogging.

(I wear glasses very infrequently, but sunglasses a lot.  I use option 1, but have been told by a co-worker about option 2)

BONUS TIP: In the winter, if you walk into a house backwards, your glasses won't fog/ will fog only slightly.
