Photochromic Polarized Sunglasses Color Unisex Photochromic Lenses Sports Sunglasses UV400 UV Protection for Outdoor Hiking [UHUKO]

[Photochromic Sunglasses] Photochromic sunglasses change color depending on the intensity of ultraviolet (UV) light. They are glasses that change color in response to UV light. When exposed to sunlight outdoors, the lenses gradually become darker, and when you go indoors, the lens color gradually fades. The lens material is mixed with halogen and silver, and when exposed to UV 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 UV 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. ☀【Ultra-lightweight & Sleek Design】The nose pad arms can be adjusted to fit the shape of your face and nose, providing a stress-free fit. Designed for Japanese people, it fits comfortably. The frame material is aluminum-magnesium alloy, achieving an ultra-lightweight design. The nose pads and temple pads are made of soft silicone material, so they won't leave marks even after prolonged wear. They also prevent slipping even during vigorous movement and are easy to put on and take off. A dedicated case is included for convenient storage, even outdoors. ☀【Highly Versatile】Beyond ordinary sunglasses, these have many functions and can be in a wide range of activities, such as driving, golf, fishing, running, cycling, mountain climbing, baseball, and other outdoor activities. ☀【Important Notes Before Purchase/Lens Test/1-Year Warranty】When purchasing photochromic sunglasses with A (day and night use) or B (daytime use), please note that the sunglasses will not change color inside a car. Photochromic lenses change color depending on the intensity of ultraviolet light, and since car windows have UV protection and the lenses do not detect ultraviolet light, they cannot change color. Outdoors, the lenses will change color according to the intensity of the sun's ultraviolet light. A UV lamp is included in the product packaging, and you can test the lenses by shining the lamp on them. Products undergo rigorous inspection before shipment, so if there are any defects in the product, we will replace or refund it. Photochromic sunglasses
