[Polarized Function] Polarized function cuts out diffuse reflections, reducing glare from glass and water surfaces, ensuring a clear view. It maintains a clear view and automatically changes to the optimal light, especially in areas with strong UV rays or bright 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 light, the silver halide breaks down into atoms, causing the color to change. When the ultraviolet light weakens, the silver halide combines again, becoming molecules and losing its color. Photochromic lenses are created by taking advantage of this chemical change. Flexible Structure & Ultra-Lightweight: The flexible hinges open wide to accommodate any contour. The nose pads can be adjusted with your fingers, ensuring a stress-free fit even when wearing sunglasses for extended periods of time. The non-slip temples provide a secure grip, even when sweating. The lightweight AL-MG alloy construction allows for a lightweight frame weighing just 28g, yet boasts high durability and strength, resulting in unparalleled comfort. [Uses] In addition to sun protection, it is also ideal for sports and outdoor activities such as golf, running, cycling, mountain climbing, traveling, baseball, driving, fishing, motorcycling, and jogging, as well as everyday use.
