There's supposed to be this stuff you can put on mirrors that keeps them from getting fogged when you shower -- I wonder if it would work on glasses? We're in the middle of cotton ginning season here (chemical coated dust, plant bits and cotton fibers in the air) and because of my asthma, I don't stir outside without one of those dust masks. I notice that my glasses don't fog at all when I wear one. People look askance at me, but hey, I'm addicted to breathing. . .
