Not happy with them. The polarization distorted around edges when they snapped into frame. They are scratched already!. It took two years before a saw a scratch with my original Kannon lenses. I am careful with them and always keep them in a case. Next time I would rather pay an extra 100.00 and get a complete new pair. I revived a call from the owner which I do appreciate. He explained the distortion is normal due to compression around the edges. You cannot see it while wearing them so it's not a huge issue. Still bummed out about the scratch after only a week but, I guess that one is on me.
