Ron, I don't wear glasses at least not yet. I do know what your experiencing though. As a carpenter working in pharmaceutical and science labs they have a strict safety policy. Safety glasses are to be worn the entire time and dust masks when required. They offer us a cleaner for the glasses that also prevents the fogging. Being an avid motorcycle rider wearing a fullface helmet in the fall/winter also has the same effect. Most motorcycle shops sell a 4 .oz bottle of no fog that also does the same thing. The cycle shop nearby sells a product called Cat Crap and they swear by it. I never tried it more than likely because of the name. Ken
