Review on KAPVOE Photochromic Cycling Sunglasses for Men and Women - MTB Mountain Bike Bicycle by Andrew Jenkins

Not the best glasses if you really want self-tinting glasses with changing tints. However, if that's not a problem for you, that's fine. Style is very subjective, you may or may not like it. But I bought clear lenses for MTB (a lot of riding in the shade) but when you get back in the sun I wanted to reduce the sun a bit. They don't offer much shade from the sun. Yes, there is a slight color difference when you hold them in the sun, but your eyes won't feel it. I've seen a SMITH demo where lenses are changed in seconds and a pair of sunglasses is enough to clean the lenses. But it's 250-300 dollars. You get what you pay for. These are clear lenses. That's all.
