[Polarized function] The polarized function cuts out diffuse reflections, suppresses glare from glass surfaces and water surfaces, and ensures a clear field of vision. It keeps your vision clear, and automatically changes the light to the optimal level, especially in areas with strong ultraviolet rays or strong light, to protect your eyes. [Photochromic function] Photochromic function is a function that changes color from "light to dark" outdoors and "dark to light" indoors. Silver halide is mixed into the lens material, and when exposed to ultraviolet rays, the silver halide breaks down into atoms, causing the color to change. When the ultraviolet rays weaken, the silver halide bonds again, becomes molecules, and loses its color. Photochromic lenses are created by taking advantage of this chemical change. [Flexible structure & ultra-lightweight] Flexible structure with hinges that open wide to fit any contour. The nose pads can be adjusted with your fingers, so you can wear sunglasses for a long time without stress. In addition, the non-slip design of the temples keeps them firmly in place even when you sweat. The material is lightweight AL-MG alloy, which makes the frame ultra-lightweight at 28g, highly durable, and strong, providing an unparalleled comfortable fit. [Uses] In addition to protecting against sunburn, it is also ideal for sports, outdoor activities such as golf, running, cycling, mountain climbing, traveling, baseball, driving, fishing, motorcycling, and jogging, as well as everyday use.
