Lens Technology : Classic Polarized HAPPY BOOST Polycarbonate Lens (Superior Color Enhancement) - HAPPY BOOST features our revolutionary patented HAPPY Lens Tech and enhances color and contrast up to 30% more than the naked eye and at least 15% more than other brands’ lenses, allowing you to enjoy more of what the outdoors have to offer. Usage Conditions : Cat. 3 lens (Sunny weather) - Darker lenses and strong mirrors shield your eyes from bright sun on bluebird days when SPF 30 is a must. Frame Material : Grilamid (Tough agains time and elements) - Constructed from Grilamid, a lightweight frame material ideal for everyday wear due to its strength and flexibility. Hinge : Metal Hinge (Storng and Durable) - A series of metal rings (barrels) that fit into each other like a zipper, with a small screw that slides inside to keep the barrels in place. Lens Coating : Mirror Coating (Reduces the amount of light entering) - A thin metallic layer on the outside of the lenses that reflects glare away from the sunglasses rather than letting it in, reducing the amount of light entering the eyes.
