【ULTRA PHOTOCHROMIC DESIGN】This magical photochromic lens is based on the intensity of sunlight and ultraviolet light, darkening the light grey lens.
【USAGE OCCASIONS】 Photochromic looking sunglasses can do a good job of stopping the dazzling effects of sunlight when you are driving, running, fishing, biking or other outdoor activities. Keep your safety always by your side.
【HIGH-STRENGTH LIGHTWEIGHT MATERIALS】Thanks to the use of innovative materials such as Kynetium™, Grilamid®, Magnesium.
【NO MATTER DAY OR NIGHT, IT WORKS WELL】Our sunglasses are made of special photochromic polarized lenses.
The intelligent color-changing feature provides good light-transmittance and clear vision.
Principles of discoloration: In ultraviolet light, the radiation will cause a chemical reaction that changes the lenses uniformly.
