I've been very impressed with these shades! They're very durable - I use them for mtn biking and while rolling around town on my electric scooter. They get a lot of abuse, and after several months the lenses haven't scratched yet. They're also comfortable and light weight, and polarized. Highly recommendThese sunglasses look great and they are comfortable.The green glasses are excellent for fishing. Can easily see and detect the movements of fish in the water!Very good quality glasses .
