RIA Eyewear tennis & pickleball sunglasses enhance the contrast of the ball against the court background while allowing you to maintain optimal depth perception to time your movement and swing (something you can't do with polarized lenses). Our polycarbonate lenses are 5x as impact-resistant as traditional polycarbonate, making our eyewear as protective as it is stylish. They have been lightly warn with some scratches on the spare lenses, the price reflects this and includes both lenses, the case, protective case, and everything shown in the pictures!
