I didn't expect these to work any more than a pair of tinted shades. But much to my surprise, they do work quite well and really dim down the headlights out there at night. With all those LED and high-beams and whatnot, these are a handy tool to have for night drives. My only recommendation would be to have a stronger frame. While it seems like a metal frame, it still feels a little weak in the hands. Otherwise, a very convenient pair of glasses to have for anyone out at night.
