Color Changing Photochromic Polarized Sunglasses Magnesium Alloy Unisex Sports UV Color Photochromic Glasses [YAYGOD] Sunglasses, [Ultra

Photochromic lenses: These lenses change 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 lens to become colored. When the ultraviolet light weakens, the silver halide bonds again, becoming molecules and losing its color. Photochromic lenses are created by taking advantage of this chemical change. Provides clear vision: Can be used in conjunction with sunglasses, can detect ultraviolet rays, has high visible light transmittance, and in strong sunlight outdoors, the lens color darkens, effectively cutting glare and reducing eye fatigue. It also has a polarizing function, cuts out diffuse reflections, and suppresses glare from glass and water surfaces, ensuring a clear view. Simple design and ultra-lightweight: The StressZeo fit is designed for Japanese people, fits comfortably, and does not cause pain even when worn for a long time. The ear hooks are made of rubber material, which increases the grip when it absorbs moisture such as sweat, preventing slipping and sliding. They are ultra-lightweight and feel like you are not wearing them at all. They are made of a durable aluminum + magnesium compound material, and the nose pads can be adjusted with your fingers, so you can easily adjust them to your preferred fit. Excellent uses: In addition to dimming, it also has a polarizing function, making it perfect for outdoor activities such as golf, running, cycling, mountain climbing, traveling, baseball, driving, fishing, motorcycling, jogging, etc. 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.
