【Lightweight and comfortable】 Weighing only 29g/piece, these ultra-lightweight sunglasses reduce pressure on the nose and temples.
【Safety】The sunglasses lenses are made of PC (polycarbonate), which blocks 100% of UVA, UVB, and UVC rays, as well as harmful blue light up to 400nm. They are also made of TR, offering superior toughness, impact resistance, abrasion resistance, anti-fog properties, and high-temperature resistance.
【Chromatic Lens】Smart cycling sunglasses automatically become lighter or darker with changes in light.
[Note] The speed of the color change depends on the intensity of the UV radiation and the temperature (with stronger UV radiation and lower temperature, the color change is slower)
