Our magnetic clip-on sunshade sets come with prescription glasses and a polarized sunshade that snaps on securely to the front rim with hidden magnets for seamless sunglasses. Made with Ultem, a highly flexible yet extremely durable plastic, each frame and matching sunshade offers lightweight comfort. It comes in green with two colors clip ons. The yellow clip on is for night driving and the grey polarized clip on is for day time use.
