Obviously to be truly protective, safety eyewear must meet a higher standard than your regular street glasses. They have to be able to stand up to all kinds of stuff flying around. According to OSHA, all industrial safety glasses must have impact resistant lenses and frames and should have a small (Z87.1) mark on the lens or the frame. Safety glasses also feature wrap-around polycarbonate lenses, side shields and UV protection.
