Mine are amber and the same ones I use for skiing. You don't really need polarized lenses but they are nice and most of the time you'll be using (you should still always have them) your goggles will be on trips above treeline or where the windchill is low enough to warrant covering your skin to prevent frostbite. This chart gives an idea of what I mean:
btw, regular sun glasses or glacier glasses used with face protection WILL fog up and become useless. If you are taking a face mask/balaclava you might as well take your goggles. Also, you can also use your goggles as sunglasses and skip taking the sunglasses, or just take regular sunglasses - last time I remember wearing my glacier glasses was the last time I was on a glacier - I have yet to hear of someone in the NE becoming snow blind - not the Ozzy kind
