Running sunglasses, also called running glasses, mainly used for outdoor running or marathon. The choice of glasses should be light and equipped with non-slip rubber temples. The material is usually polycarbonate or TR90. The frame of the TR90 is lighter than the polycarbonate frame and is not easily deformed. Polarized lenses should be used for lenses, and dark-colored lenses for glare weather. For cloudy weather or evening, light-colored lenses should be used.
