☀[Photochromic Sunglasses] Photochromic sunglasses change color depending on the intensity of ultraviolet light. They are glasses that change color in response to ultraviolet light. When exposed to sunlight outdoors, the lenses gradually become colored, and when you go indoors, the lens color gradually fades. The lens material is mixed with halogen and silver, and when exposed to ultraviolet light, the halogen and silver decompose, causing the lens to darken. This chemical process is what makes them photochromic sunglasses. Please note that if the ultraviolet light is weak, it will take longer for the lenses to change. ☀[Polarized Lenses] Polarized sunglasses provide a clear view. They effectively cut out glare and reflections from road signs, obscuring white lines on the road surface, causing eye strain from glare from below while running, and making it difficult to discern the contours of the green while golfing. They are gentle on the eyes and provide protection. ☀[High-Quality Materials] FEISEDY is dedicated to creating sunglasses made with high-quality materials at reasonable prices.

Therefore, please be aware that the color change may be weaker in places with weak ultraviolet rays, such as offices, indoors, or on cloudy days. For details on the photochromic effect, please refer to the included ultraviolet light (blue light) and the photochromic instruction manual. Black and yellow glasses do not have a color change effect, so please check before purchasing.
