Great glasses! I can wear while driving and still read details on a map or info showing up on my dashboard screen. My last pair (same mfr number) lasted years and finally succumbed to my abuse. Ordered 2 pr from the Sunglass Guy. Only thing different is that these have more of a shiny black finish instead of the matte black my original pair had. I'm guessing the mfr changed style/finish/materials since the last time I ordered from a different vendor because everything else (shape, strength, sizing) seems identical to my original pair.
