I have found that I really need two pairs of glasses; one for snow and the other for regular travel. Everything I have had that work on snow screen out too much of the view in shadows to work for regular hiking, particularly off-trail. It is really hard to hop talus if all the shadow area is black. I use glacier goggles on snow, and then cheap regular sunglasses for hiking. Because I really trash my sunglasses and loose them often, I buy cheaper glasses and just replace them yearly. I once had $200 transition prescription bifocals, and lost them - spent hours looking for them but to no avail. They darkened shadows too much, so I took them off while hopping boulders and put them in my pocket. They evidently fell out - the pocket had a button but not a zipper.
