WHAT SHOULD I DO IF THE MASK FOGS MY GLASSES?

When the mask is put on, the nose foam should end up on your nose. Behind the nose foam, the mask has a built-in shapable nose-clip. The nose-foam creates an airtight seal to reduce hot and moist air to leak out and fog your glasses. Finally, put your glasses just over the top of the mask. This will reduce fogging even further.
