While it may not be ideal for customers seeking a luxurious or substantial feel, it is a lightweight and user-friendly pair of sunglasses. What are photochromic lenses? These lenses change tint depending on the amount of ultraviolet light. The lenses change color depending on the brightness; they function as light-colored lenses indoors and as sunglasses outdoors. Indoors, on cloudy days, during winter, or in the early morning, when there is no or very little ultraviolet light, no color change will occur. Polarized lenses have a special film called a "polarizing film" inside the lens. These lenses cut out glare from roads, water, and snow, as well as dazzling reflected light from car and building windows, resulting in a clearer field of vision. It eliminates glare on the water's surface, making it easier to see the fish underwater, so it's an essential item for anglers. In addition, when driving, road reflections are eliminated, making white lines clearly visible, and in winter sports, bumps and unevenness on the snow surface that are difficult to see due to reflections become clearly visible.
