Perched gently on top of your eye glasses frame, this butane powered device directs intermittent jets of flame to heat the outer surface of each glass lens. The inner surface heats via conduction. Resultantly, your glasses will not fog up upon coming in from the cold.

       It would also help with safety goggles and glasses and for people who aren't eligible for correction.   

       Might I suggest Nichrome wire frames instead of open flame? Not sure how well they would heat the middle of the lenses though.
