For those of us in the medical field who need to lip read, to help with hearing. You might find these masks helpful.
Looks like a great idea. My only possible concern is wondering if they wouldn’t lead to more condensation on glasses.
@MDB I’ve been nursing for 52 yrs now, and worn glasses for 45 of those yrs. (retired 2 weeks ago) Fogging of my glasses has always been a problem when wearing masks for as long as I can remember. The firmer the mask the worse the fogging situation became. This is why I opted not to do theatre work where I would have to wear a mask most of the day.
