How do I reduce glasses fogging with a face mask?
Choosing a well-fitting mask, ideally with a moldable nose-bridge wire, should help alleviate the common problem of glasses or other eyewear fogging when your nose and mouth are covered with cloth. The most effective way to reduce fogging when you’re wearing a mask is to create a better seal between the top of the mask and your skin, leaving less room for air to escape your mask and reach your glasses.
