The fog means it’s not fit properly. Air should not be escaping over the bridge of the nose it should diffuse out of the entire mask. Either the strips across the top are not being bent correctly to contour the nose or the mask just can’t be made to fit your face shape and you need to try something else.

No, it doesn’t. Exhaled breath emitted through the filtration material can still cause glasses to fog.
