I wear glasses. They constantly fog up with these hospital type masks. Obvious my breathing is going around the mask not through it. Does nothing to stop viruses.

That's the point. It stops your your breath from shooting out as a high pressure jet in a cone line area in front of you.

Instead it stays around you and reduces the pressure gradient outside the mask.

Would you be comfortable with surgeons working on you without a mask on? Why is this different?
