[Note] Photochromic lenses change color depending on the strength of the sunlight's ultraviolet rays, so please be aware that the color change and dimming will be weaker in environments where the ultraviolet rays are weak, such as at work, indoors, or on cloudy skies. Please check the dimming effect using the included ultraviolet irradiation lamp (blue light) and test card. [Clarier Visibility] The photochromic lens automatically adjusts the color density of the lens according to the strength of the ultraviolet rays, providing the optimal visibility. Easily adapts to complex weather conditions, providing clear and comfortable visibility on sunny days, rainy days, snowy days, and cloudy days by effectively cutting out intense sunlight, glare from roads, water, and snow, and glass and glare when driving or fishing. [High-speed dimming] Photochromic lenses change color depending on the strength of sunlight's ultraviolet rays. In sunny weather, the lens becomes darker due to the intense ultraviolet rays, effectively protecting our eyes from the sun's strong rays.In cloudy weather, the light is slightly suppressed and the lens color becomes slightly diluted, ensuring brightness of vision and preventing accidents. Maximizes visual fatigue: The color density of the lens changes depending on the amount of UV rays, and even if it is cloudy, if the UV rays are strong, the color of the lens will become darker. It prevents eye fatigue and reduces the appearance of age spots and wrinkles around the eyes. It can be used in all weather conditions and can be left on even at night. [Pursuing comfort] The lightweight AL-MG alloy design weighs approximately 26g, and the metal frame has an elegant texture, and uses electroless nickel plating technology to provide strong stability and prevent the surface from peeling off even when worn for a long time, giving it a different quality.
