[Caution] Photochromic lenses change color depending on the intensity of ultraviolet rays from sunlight. Please be aware that the photochromic effect will be weaker in areas with low UV levels, such as indoors, inside buildings, or on cloudy days. Please check the photochromic effect using the included UV light (blue light) and test card. 【Photochromic】Photochromic lenses are high-tech lenses that change color depending on the amount of ultraviolet light. They can be used as eyeglasses indoors and as sunglasses outdoors, offering two uses in one pair of glasses. In addition, we also offer lenses without the photochromic function, so those who prefer lenses that are always dark can choose the non-photochromic lenses. [No need to switch between glasses and sunglasses] Photochromic lenses change color in response to ultraviolet light, so they appear almost transparent indoors where there is no UV light. Wearing tinted sunglasses indoors can feel strange, but with photochromic sunglasses, you can wear them all the time. Since you don't need to switch between glasses and sunglasses depending on the situation, it reduces hassle and the amount of luggage you have to carry. Also, even if you spend the whole day outdoors or on days with unpredictable weather, the lenses change color according to the brightness, so you can stay comfortable. 【Stylish】With a square design that complements Japanese facial features and slender temples, these sunglasses beautifully accentuate the contours of the face, making them a fashionable choice.
