how do I keep my safety glasses from fogging up when I'm working hard
outside in cold weather?

Some glasses use more ventilation than others. Just try a different

They have many many styles to choose from and by far stock a wider
variety of saftey glasses that I have seen, and cheap prices. When I
searched for anti-fog I got 33 results. Link:
