I bought my goodr sunglasses straight from the company's website (not through Amazon), but I think the info is relevant enough to share here.
I love the look of these sunglasses and they stay put REALLY WELL while running - they feel great! BUT, I'm afraid they're not going to last long, which bums me out. I wear sunscreen when I run, and my face sweats . . . so the lenses get a bit greasy/slimy. Cleaning them helps with that, but the polarized coating doesn't seem very sturdy. I'm only a couple weeks in, and there are odd black spots showing up on the outer surface of the lenses. I've gotten more life out of $10-20 Target sunglasses.
