try what I do for a swim mask, spit in it and rub it all over the lens (inside), try to get the streaking out, then wash those nasty glasses at the end of the dayWe can put a man on the moon - but we cant come up with anything the works for foggy glasses!!!!!
I only wear my normal glasses when I climb, since safety glasses arent an option so I dont fog up, safety squints FTW
