I wear glasses, so it's a little harder to find the perfect lenses. Regular transitions barely get it done. Colors can be hard to distinguish. Also, cloudy or foggy days on the snow were ridicules. The snow would reflect the light, thus turning the lenses dark. I couldn't see crap! I would usually just take them off and hope for the best. Sadly, they quit making my hands down favorites. They were called autumn gold transitions. They were yellow with no sun and a nice brown shade in the sun. The brown shade was much like the blue blockers. The ones I wear now are called Hunters Gold. They're ok but don't turn as dark as I'd like.
