How bad/dangerous are polarized lenses for alpine environment? Comments in various glasses/goggles threads on here suggest there is a danger of not distinguishing between ice and snow or not seeing subtleties on the surface of glaciers that could be hazardous. Is this a serious concern?
I'm asking because I tried on all Jublo mountain glasses and the Explorers fit my face the best. I want photochromic lenses (i.e. Zebra or Camel, NOT Spectrum) but the Explorer only comes with the Camel lens, which is polarized (Zebra is not). Trying to decide to go with Explorer/Camel or just settle for less ideal fit to get the Zebras (Montebianco or Bivouak).
