What’s the best ‘‘COVID-19” mask that won’t fog up glasses?

Some people wear a clear shield type of mask, either covering the entire face, or just the nose/mouth/chin. I've not seen too many of those nose/mouth types, but I've seen lots of whole face shields. They may not be as effective as N95 masks, but something is better than nothing.......Show more

COVID-19 masks are not for filtering. they are designed more as "splash guards".
and if you wear them properly, they won't fog up your glasses much, if at all. you MUST wear the mask over your nose, and set the glasses on top of the mask, NOT mask in front of glasses. putting the mask in front of the glasses allows the breath to flow upward easily. with the glasses holding it down, your breath should go to the sides of the mask.
if it DOESN'T, then your mask is on too tight. you need to get one that fits you more loosely. remember, the idea is NOT to filter your breath. the coronavirus has not been proven to be airborne. it travels on spit, in sneezes and coughs. the sides of the mask should be open and loose, so your breath has a way out that is not "upwards".
if you cannot find a mask that fits right (maybe you just have one of those weird shaped faces) then you should use a face shield instead of a mask. it accomplishes the same thing, and allows for more airflow....Show more
