[OTC.web] 002MN Photochromic Sunglasses with Blue Light Blocking, Darkening Lens, Men's, Large Size, Semi-rimless, Stylish, Cool, UV Protection, (GM

These are photochromic lenses that change tint depending on the amount of light. They change to a light tint (approximately 10% tint) indoors or at night, a medium tint (approximately 50% tint) inside a car, and a dark tint (approximately 90% tint) outdoors or in bright sunlight. In addition, they cut blue light by an average of approximately 35%. These are stylish blue light blocking sunglasses with a half-rim design using metal material. They are cool, large-sized, and stylish color-changing sunglasses in gunmetal or silver, perfect for the edgy, slightly rebellious man. Inside a car, the lenses will have a moderate tint (approximately 40-50% density) *they will not become completely dark. Car windshields have UV protection. Ordinary photochromic lenses change color in response to ultraviolet light, so they are not effective inside a car. ARTtypeEX lenses react to visible light, so they can be used inside a car. Outdoors, the lenses will have a dark tint (80-90% density). Ordinary photochromic lenses are easily affected by temperature changes, and will not darken as easily in high temperatures. ARTtypeEX lenses have a much higher tint density compared to ordinary photochromic lenses, and will perform well even in high-temperature environments. A lens cleaning cloth and folding case are included as a service. Lens size: approximately 55mm wide x 34mm high; bridge width approximately 17mm; temple length approximately 145mm; overall width 140mm. The lenses and frame are made overseas, but assembly is done domestically. Visible light dimming data GRAY: Change in density 93% (without UV light), transmittance approximately 87%. When UV light is applied: 23°C → density approximately 93%, 35°C → density approximately 85%. When UV light is removed, the density returns to 30% in approximately 13 minutes (at 23°C). Visible light dimming data BROWN Change in density 90% No UV light Transmittance approximately 89% When UV light is applied 23℃ → density approximately 90% 35℃ → density approximately 80% When UV light is removed it returns to density 30% in about 12 minutes *at 23℃
