Our color changing frames magically transform from clear to purple or clear to blue when exposed to the sun. #lifehack tip: if your frames change color, it's also time to put on sunscreen!
Please notethe color changing effect can lessen over time. The magic dye loses its magic after repeated use. We suggest storing these away from sunlight to lengthen the effect. This is not a "defect or damage" for warranty purposes, as they will still work just as well as sunglasses if the color change fades a bit, so if you want color that will last forever, these might not be right for you!
