They fit nicely over my glasses and seal good around my face. I was removing drywall off a ceiling and with that blown-in insualtion was falling on my head and face. It protected my face well. The only problem was with no real air movement in the room I started to sweat then the goggles started to fog up and then moisture started to get on the goggles and my glasses.
These safety glasses might be useful when working outside in the wind, but in my basement they seem to fog up in a minute. These glasses protect my eyes, visibility gets so poor so quickly that they probably increase my chances of an accident.
These goggles are made from a soft plastic that makes them the most comfortable set I've ever owned (and I've owned many sets over the years). Great, extremely transparent lens makes vision obstruction a non-issue, and the best part is, these goggles are actually big enough to go over my extra-large glasses.
Pros: Durable, Easy to Clean, Lots of Features, Easy to Use, Sturdy, High Quality, Looks Great, Stylish, Good Size & Weight, Nice Design
