[Next-Generation Photochromic Sunglasses] These photochromic sunglasses change lens color according to the intensity of ultraviolet light. Outdoors, the lenses gradually darken in response to ultraviolet light, and gradually lighten again when you go indoors. The lenses use a special material containing halogen and silver, and the lenses darken due to a chemical reaction when exposed to ultraviolet light. Please note that the color change may be slower if the ultraviolet light is weak. [Polarized Lenses] Polarized sunglasses keep your vision clear and effectively cut out glare from road signs and road surfaces, as well as glare while running. Furthermore, they make it easier to see the undulations on the green when playing golf, and gently protect your eyes.

[Caution] Photochromic lenses change color depending on the intensity of ultraviolet light. In places with less ultraviolet light, such as offices, indoors, or on cloudy days, the color change may be weaker. Please check the included UV light (blue light) and photochromic instruction manual.
