Even with a hard coating Polycarbonate has to be handled carefully, and should cleaned with soap and water and dried with paper tissue.

Compliance with requirements to wear safety glasses used to be a big problem in industry.

If you offer a selection of stylish safety glasses, that are appropriate for your work environment, you will find that compliance is no longer a big problem. No, OSHA does not approve safety glasses, or any other personal protective equipment for that matter. See similar questions...

If you use lathes, saws, sanders and other power tools at home, you need protective eyewear. It should cover not only the front of your eyes, but also the sides and top, so small airborne particles can't get in. Hardware stores sell shields that will usually fit over your glasses. But if you work with tools a lot, you'll avoid fogging problems and be more comfortable if you buy a specially fitted pair of safety glasses with polycarbonate lenses and frames from an eye care practitioner.
