This is a photochromic eyeglasses. When exposed to outdoor sunlight, the lenses absorb ultraviolet rays to form a protective layer that changes the color of the lenses. The stronger the UV rays, the darker the color of the protective layer. The photochromic design can adaptively change the transparency of the lens under outdoor sunlight exposure, making it very suitable for outdoor activities such as cycling, running, fishing, and driving.
