I bought a pair of Serrngeti glasses.
Technology - Serengeti Eyewear Best sunglasses I have ever had by far, I have the amber lens and while I don't drive with them on at night, you can use them all the way till dusk and still see well, wearing these results in way less eyestrain than other glasses I have had, even high dollar Ray Bans. These weren't cheap however, $126 in 2013, BUT eyes are worth saving, I don't know a single blind driver.
