The lenses are great. Crystal clear vision and polarized. Unfortunately, the frame is a piece of junk. The frame is poorly designed and it broke on both sides just above the lenses the very first time I wore the glasses. The fact that the frame broke in the exact same spot on both sides of the glasses highly suggests that it is a design flaw.  You can see that the plastic is actually very thin by design in the region where it broke.  I had to tape the frame together so I could continue wearing them while I was on vacation. Overall, I do not recommend purchasing the glasses.
