I've mailed my parents a couple of masks with a piece of vacuum cleaner filter between two pieces of cotton but I definitely had the problem with exhalations fogging my glasses. On the other hand I have that with n95s, too, which is why I have a big full face respirator that I wear for serious tasks like removing old carpet, etc. And now perhaps grocery trips as well, good grief.
