I have yet to find anything that will stop my eye glasses from fogging up while wearing a winter face mask. Im looking for ideas that may have worked for people. Thus far I have tried and given up on. - Cat crap - Toothpaste - Spray on anti fog - Dish soap - Shaving cream I usually just dont wear my glasses when its cold enough for a face mask because I just cant keep them un fogged. Any ideas would be appreciated. Thanks!
