【ULTRA PHOTOCHROMIC DESIGN】When the sunlight changes, the tint changes. The science behind it is complicated but the result is as simple as that. Each Photochromic lens contains millions of organic molecules that react to UV light. When exposed, the molecules change shape, absorbing light and making the lens darker. When there is less UV light, the opposite reaction takes place and the lens tint becomes lighter. Like all of our lenses, our Photochromics are impact resistant and optically correct with 100% UVA, UVB, UVC protection.

【100% UV400 PROTECTION】All of our lenses block 100% UVA, UVB, and UVC rays and harmful, high energy light to 400nm. These rays are a leading cause of cataracts, skin cancer and wrinkles around the eyes -- all great reasons to block them out.

【
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】T
hanks to the use of innovative materials such as Kynetium™, Grilamid®, Magnesium. A Swiss technology, this incredible thermoplastic is the material used in all of our sunglasses (with the exception of our metal frames). Its extreme flexibility, durability and light weight make it the perfect material for performance eyewear.

【NO MATTER DAY OR NIGHT, IT WORKS WELL】Our sunglasses are made of special photochromic polarized lenses. When driving at night or into a dark environment, the lenses are lightcolored transparent to enhancing the visibility while effectively reducing the glare.
