Review on 🛡️ Classroom Protection: Advanced Anti-Fog Shield with Registration by Ronny Prather

I really have no complaints about these glasses. They fit comfortably, are lightweight and I haven't noticed any fogging issues. They're not necessarily dazzling, but I can tell I'm looking through a "clear lens" when I wear them. After wearing them for about an hour my face starts to sweat a little under the goggles so it's fair to say they block airflow (that's the whole point of getting goggles without ventilation) . But. The point on each side of the goggles where it attaches to the elastic is moved slightly away from my face by the elastic, meaning these goggles are not completely airtight. I use these goggles in place of an open face shield and they definitely offer better protection than a face shield, but if I'm concerned about large spills (like chemicals or contaminated water) or need a totally airtight fit, I might not be so happy.
