All those slit glasses do is reduce the amount of light that hits the eye in order to prevent snow-blindness. They do not however polarize light. The problem with snow is that it reflects light very well, so without protection, Your eyes get a massive photon blast, way more than is good for them. - Hence the cool sunglasses and the ski/snowboarder-tan.
