Anyone got some good cleaning tips for these lenses?? The first time i tried i used ammonia and water like i normally do and it scratched the lens. evidently they use some kind of anti fog film. then i read the directions and used soapy water but made the mistake of rinsing them under the faucet. This of course got water in between the two lenses!! The next lense i used soapy water and carefully rinsed them and dried them w/ a soft towel and it still scratched the lenses. the directions say to remove the lens from the frame to clean. I did this once and by the time i got it back in it had finger prints all over it!! :| I can clean the outside w/out to much difficulty but the inside is a pain. anyone else find these a pain to clean??

Other than that they are great for keeping the fog at bay, just a pain to clean and not scratch the lense.
