If you get a nice big goggle with a good lens, you'll be amazed at what it does for your vision.
I ride whistler too, and I personally think the Oakley HI yellow lens is perfect for those exact conditions you mentioned. It really boosts contrast. You can get it in any oakley goggle, crowbars, splices, aframes, whichever fits your face best.
Skiing's rad, hating's bad.
