I wear glasses myself and have never had problems with my goggles fogging. However, depending on the temperature, I do have trouble with my glasses fogging when my goggles are on. I've tried a number of things to stop it but most things don't work. I find the only thing that keeps them from fogging is to keep my goggles on my helmet until I'm moving and then pull them down. When I'm moving they don't fog up. Its just when I am strapping in or riding the lift.
