☀【Photochromic sunglasses】Photochromic sunglasses are glasses that change color in response to ultraviolet rays. When exposed to sunlight outdoors, the lens gradually becomes colored, and when indoors, the lens color gradually becomes lighter. The lens material is mixed with halogen and silver, and when exposed to ultraviolet rays, the halogen and silver decompose, and the lens color becomes darker. By using this type of chemistry, they become photochromic sunglasses. Please note that if the ultraviolet rays are weak, the lens will take longer to change. ☀ [Polarized lenses] Polarized sunglasses give you a clear view. They reduce glare and scattered reflections from road signs, make it difficult to see white lines due to reflections from the road surface, tire your eyes from the glare from below while running, and make it difficult to grasp the contours of the green when playing golf. Polarized sunglasses effectively cut out this light, providing gentle protection to your eyes. ☀ [Ultra-lightweight & sleek design] Compared to regular glasses, the integrated nose pads provide a better fit and reduce pressure on the nose. Frame material: Aluminum magnesium alloy, ultra-lightweight, and the nose pads and temple pads are made of soft silicone material, so they are less likely to leave marks even when worn for long periods of time, and they can be easily removed and put on, so they come with a special case for outdoor use and convenient storage. ☀ [Very useful] In addition to ordinary sunglasses, these have many functions and can be used in a wide range of situations, such as driving, golfing, fishing, running, cycling, mountain climbing, baseball, and other outdoor activities. ☀【Caution】Photochromic lenses change color depending on the strength of ultraviolet rays from sunlight, so please note that the color change and photochromic effect may be weaker in places with weak ultraviolet rays such as offices, indoors, and cloudy days. Please check the included ultraviolet irradiation lamp (blue light) and photochromic instructions for the photochromic effect. Black and yellow glasses do not have a color change effect, so please check before purchasing.
