[New generation photochromic sunglasses] These photochromic sunglasses change the color of the lenses depending on the strength of UV rays. When outdoors, the lenses gradually become colored in response to ultraviolet rays, and when indoors, the color gradually returns to normal. The lenses are made of a special material containing halogen and silver, and when exposed to ultraviolet light, the color of the lenses darkens due to a chemical reaction. Please note that if the UV rays are weak, discoloration may be delayed. [Polarized Lenses] Polarized sunglasses keep your vision clear and effectively block reflections from road signs and road surfaces, as well as glare from light while running. Furthermore, when playing golf, it becomes easier to see the undulations on the green, gently protecting your eyes.
