@SuperFloppies Not to argue the main point here, but as a fellow glasses-haver let me recommend investing in some antifog wipes, because I recently did and they do actually work.
The disadvantage is that when fog *does* overcome the antifog, it kinda goes straight to "micro droplet" form condensation, which takes longer to clear than "fog". But combined with a well-fitted mask it mostly keeps them clear from breath fog.
