I noticed something that you may want to keep in mind that the article didn't bring out. When you go night skiing or snowboarding, you'll want to make sure you have a pair of clear goggles so that you have maximum visibility but still have protection for your eyes. Also I personally prefer goggles over sunglasses, they keep your face much warmer and usually don't come off if you fall (of course they are usually attached to my helmet). I have Scott goggles with rose-colored lenses and if I remember correctly I got them for less than $100 on sale. I've also never had a problem with fogging even at eight below.
