i wear those sunglasses that cover all your glasses. they have a nice wide ear piece, so i have a good base for my rear view mirror. they do tend to fog up, but by spitting on them ( an old diving trick) they work better than nothing over my glasses, as they keep my eyes from watering from the cold, especially going down hill. i just had the lenses of a pair changed changed over to clear. but i had to get optical lenses, since they couldn't find any clear lenses that came with the sunglasses, i guess cuz they were sunglasses! so it was a bit more expensive than i would have expected, about $100 canadian. i imagine you guys in the states could get them for a lot less than that, as canadian prices are not low.
