Please be aware that according to the CDC, a face shield alone doesn't block aerosol transmission of droplets they simply go around the edges & are inhaled. The are meant to provide and "extra layer" of protection, specifically to help keep particles out of eyes & off skin, and to be used together with a mask. In my dentists' office, they use mask & fitted glasses, covered by a shield.

Oregon, which has required masks since mid-March, has many places that don't allow people in with only face shields. I agree that they're comfortable...but they just aren't as safe as a mask, so aren't permitted in many places. Lots of places in Oregon also don't allow gaiters or handkerchief "masks." Our small town of 8,000 (which balloons to over 50,000 most weekends due to tourists) has only had two outbreaks: the first was a family of four where the father brought Covid home from a seafood processing plant; family was quarantined and no one else got Covid from them. Second was five motel workers who caught Covid from guests after an extremely nice (read: busy) weekend in August; again, all five were quarantined --no spread whatsoever. There have been huge spreader events due to people renting vacation rental houses for a weekend or week: they're so expensive (just the cleaning fee starts at $200) that most renters invite lots of friends. It's common to see 6 to 8 or more vehicles outside a VRD (vacation rental). One single week-long rental resulted in over 200 people contracting Covid, thankfully, none of them here. The single person who infected others wasn't really sick until after he got home and had infected fellow workers. There were eight separate households represented in that little gathering at the coast. In spite of the danger, we still see multiple cars outside VRDs most weekends. ...some people's kids...

@th1 Where do you get that type of frame?
