I was looking for glasses for night driving because I work transfers for the season on an island, many hours. I ended up choosing these only because, from the few options available, they were the most expensive (you get what you pay for) and they claim to have polarized lenses. The polarization does all the work! Although at first use they feel a bit "strange," you get used to them and now I can't part with them. As soon as the sun sets, I put them on immediately. I no longer get headaches from car lights. They are especially effective with those inconsiderate drivers who drive around with their high beams on (headlights).

Note that their use is to reduce reflection and brightness from the lights of oncoming vehicles. If you drive in complete darkness, it might be better not to wear them, as the yellow lens slightly darkens visibility. But if you drive on roads with a lot of oncoming vehicles, I recommend them. They come with a durable protective case and a cleaning cloth.
