yeah, man, not a good idea to wipe the inside of the lense, but oh well, we all have to do it eventually. i have, and mine dont fog that often. like its been said, leave them on your face, forehead is a bad place... and if they fog because you are hot, just take them off and wave them in the air. that, and skiing or riding a fast lift. airflow solves most problems. if they fog after a fall, try to get the insides as dry as you can. any snow or water will make them fog even easier.
