I found if I put these glasses on like normal, put on headphones, then pull the glasses out 3/16" or so in warm/hot weather they don't fog up or get covered in sweat. To prevent fogging in winter I coat both sides in Cat Crap(tm) and buff.
OSHA doesn't care tho
I probably purchase 40+ safety glasses from ULINE every year. They have some that have a gasket foam that mold to your face and optional elastic band with interchangeable arms. Most anti-fog glasses preform well.
On the job, I care what OSHA says. More importantly, I want my coworkers to go home safely whether they are still employed or not is on them. Both on the job, and off the job, I apply Mike Rowe's "Safety Third" principle. I assume that nobody is more concerned about my safety than me. I've cut with no eye pro, with safety glasses, with a helmet and face shield, and with glasses and a helmet and a face shield. Under all 4 conditions, I've had crud get in my eyes. The helmet and face shield have done a much better job than glasses alone, especially for larger debris. With the face shield, I may end up with some very fine dust over the course of the day. With glasses alone, I've not only had large chips come up under them, but more than once I've had a small limb or briar find its way under them. If I'm cutting in the back yard, it's a toss up as to what I'll have on, but I never take the chainsaw somewhere without my helmet.
