Note: Resin lenses are easily scratched. Please use clean water or special cloth to wipe.
Color-changing glasses need to be exposed to sunlight for 5-10 seconds before they gradually change color. The color of the lenses changes according to the intensity of ultraviolet rays.
Note: Color-changing sunglasses will only change color in the sun, not in the car (because the car windshield will isolate ultraviolet rays)
