I have a referral code for 10% off SunGod products. They sell hard-wearing sports sunglasses and ski goggles, mostly with a mirrored effect and polarised lenses. The lenses are nice and clear, I also have Goodr sunglasses and I would say the lens is much clearer in the SunGods (they are more expensive though).
