Photochromic sunglasses are glasses whose lenses change color depending on the intensity of UV rays. They react to UV rays, gradually tinting the lenses when outdoors in the sun, and gradually fading when indoors. The lenses are made of a mixture of halogen and silver, which break down when exposed to UV rays, darkening the lens color. This chemical reaction results in photochromic sunglasses. Please note that the lens color change takes longer when exposed to weak UV rays. ☀ [Polarized lenses] Polarized sunglasses provide clear vision. They effectively cut out light from road signs that are glaring or reflecting light, from the road surface that makes it difficult to see the white lines, from light reflecting from below that can tire your eyes while running, and from golf greens that make it difficult to grasp the contours of the green, providing gentle protection for your eyes. ☀ [Ultra-lightweight & sleek design] The nose pad arms can be adjusted to fit the shape of your face and nose, and the stress-free fit is designed for Japanese people, and the frame material is aluminum magnesium alloy, making it ultra-lightweight.The nose pads and temple pads are made of soft silicone material, so they are less likely to leave marks even when worn for long periods of time.They also prevent slipping even during intense movements and are easy to put on and take off.They come with a dedicated case, making them convenient to store outdoors. ☀ [Very useful] In addition to ordinary sunglasses, these have many functions and can be used in a wide range of applications, making them perfect for outdoor activities such as driving, golfing, fishing, running, cycling, mountain climbing, baseball, etc. ☀ [Pre-Purchase Notice/Lens Test/1-Year Warranty] When purchasing tinting sunglasses with either A.
