☀ [Photochromic Sunglasses] Photochromic sunglasses are glasses that change color depending on the strength of the 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.By using this type 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.
