UNCROWD Photochromic Lens Sunglasses TRUENO Trueno Black x Gold Frame I think it's a beautiful item, only worn a few times. Product Description These are biker shades that pay homage to the "CLUBMASTER," a world-renowned model of the browline style. These lenses use photochromic technology, which adjusts the tint according to the amount of UV light. They are clear lenses in normal conditions, and turn smoky gray when exposed to UV light. They are clear indoors or at night, and gray outdoors during the day, so these biker shades serve two roles in one. Made in Japan, they are lightweight and designed to fit Japanese faces, providing excellent comfort. Please refrain from purchasing if you are sensitive to used items.
