The new Prizm lenses are supposed to give a better contrast than the previous Oakley goggle lenses. I'm interested in the Prizm rose lens for low light conditions. (It's for my Airbreak snow goggle.) However, I also read messages from people that still prefer the persimmon or yellow lenses for low light conditions. So I was wondering: does the Prizm rose really improve contrast? And is it an improvement over the persimmon or yellow lenses for low light conditions? Thanks!
