【Photochromic Sunglasses】Photochromic sunglasses change color in response to UV strength. These glasses gradually darken when exposed to sunlight outdoors and lighten when indoors. The lenses are made by mixing halogen and silver, which decompose under UV light, resulting in darker lenses. Please note that changes in lens color may take time when UV exposure is weak. ☀【Polarized Lenses】Polarized sunglasses provide a clear view by cutting glare and reflections from road signs and surfaces, making it easier to see white lines. They reduce eye strain from light reflections while running and help with visibility of undulations on the golf green. ☀【Ultra-Lightweight & Sleek Design】The nose pad arms can be adjusted to fit the shape of your face and nose, providing a comfortable fit designed for Japanese users. The frame is made from aluminum-magnesium alloy, achieving ultra-lightweight characteristics. The soft silicone material on the nose and temple pads minimizes marks even with prolonged wear, keeping the glasses stable during vigorous activities. They come with a dedicated case for convenient storage outdoors. ☀【Versatile Use】These sunglasses multiple functions beyond regular sunglasses and are suitable for various outdoor activities such as driving, golfing, fishing, running, cycling, hiking, and baseball. ☀【Pre-Purchase Notes / Lens Testing / 1-Year Warranty】When purchasing photochromic sunglasses (A: day/night use, B: day use), please note that they do not change color inside a car due to the UV-blocking properties of automotive glass. The lenses will change color outdoors based on UV strength. The product packaging includes a UV lamp for testing the lenses. Each product undergoes strict inspection before shipping, and any defects will be eligible for exchange or refund.
