☀【Photochromic Sunglasses】Photochromic sunglasses are glasses that change color in response to UV rays. When exposed to sunlight outdoors, the lenses gradually become tinted, and when indoors, the lens color gradually fades. The lens material contains halogen and silver, and when exposed to UV rays, the halogen and silver break down, causing the lens color to darken. This chemical reaction makes them photochromic sunglasses. Please note that the lens color change takes longer when the UV rays are weak. ☀ [Polarized lenses] Polarized sunglasses provide clear vision. They effectively cut out light from road signs that are glaring or reflecting light, from the road surface that makes it difficult to see the white lines, from light reflecting from below that can tire your eyes while running, and from golf greens that make it difficult to see the contours of the green, providing gentle protection for your eyes. ☀【Ultra-Lightweight & Sleek Design】Compared to regular eyeglasses, the integrated nose pads provide a better fit and reduce pressure on the nose. The frame material is aluminum-magnesium alloy, making it ultra-lightweight. The nose pads and temple pads are made of soft silicone material, which prevents marks even after long wear. They also prevent slippage even during intense movement. They are easy to put on and take off, and come with a dedicated case for convenient storage, even outdoors. ☀ [Very useful] In addition to ordinary sunglasses, these have many functions and can be used in a wide range of applications, making them perfect for outdoor activities such as driving, golfing, fishing, running, cycling, mountain climbing, baseball, etc. ☀ [Please note] Photochromic lenses change color depending on the strength of UV rays in sunlight. Therefore, please note that the color and photochromic effect may be weaker in places with weak UV rays, such as an office, indoors, or on cloudy days. Please check the included UV light (blue light) and photochromic instructions for photochromic effect. Black and yellow glasses do not have a photochromic effect, so please check before purchasing.
