☀ [Photochromic sunglasses] Photochromic sunglasses are glasses that change color in response to ultraviolet rays, and when exposed to sunlight outdoors, the lenses gradually become 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 color of the lenses becomes darker.Through the use of this kind of chemistry, photochromic sunglasses become photochromic sunglasses. Please note that if the UV rays are weak, it will take time for the lens to change. ☀【Polarized Lenses】Polarized sunglasses provide clear vision.Polarized sunglasses can effectively block the light from glare and diffused reflections from road signs, road surface reflections that make it difficult to see the white line, fatigue of the eyes when running, reflection of light from below, and difficulty in understanding the ups and downs of the green when playing golf. ☀【High Quality Materials】FEISEDY is dedicated to making sunglasses with high quality materials at reasonable prices.
