I bought Protos glasses for my new protos lid. They are great. I use them for cuts above head, or when my bar is sending sawdust at me. The mesh faceshield is fogless, of course, and I'm not too concerned about getting pitch on it (never noticed pitch on it...). When I'm done cutting, I push the glasses up into the lid. Since my glasses are only deployed during the cut, they do not have time to fog up. I live in Florida, so there is generally high humidity in the air. The glasses do not get scratched because the mesh or the lid are protecting them. I do not drop them to the ground (saw a glasses dropped dq in comp climbing two years ago, and of course it's also bad to drop eye pro while actually working...). If the glasses get a smudge, I can just not wear them. It's usually pretty easy to work through a smudge. Shortly after I started using them, I became adept at raising and lowering them without smudging them. The Protos eyewear system has become the main reason I prefer the Protos helmet. I think the Kask helmet is great, so please don't misread me. I just really like the Protos eyewear system.
