Your daily work horse, the Zeal Essential polarized sunglasses blend a throwback look with modern features to suit your style and eye protection needs anytime, anywhere. Polarized lenses reduce 99% of visible glare from water, snow, sand and pavement for increased visual acuity and decreased eye strain. Impact- and scratch-resistant, the injection molded polycarbonate blend lenses are resilient, crisp and crystal clear. Lenses meet the rigorous ANSI (American National Standards Institute) tests for impact resistance while blocking 100% of harmful UVA and UVB light. Instead of crude oil, frames are made of Z-Resin(TM) a bio-based plastic derived from castor bean seeds, and lightweight nylon for a resilient, consistent fit. Hypoallergenic rubber nose pads and temple ends grip during exercise and hot weather for a secure fit. Includes a semirigid hardshell carrying case and a soft microfiber case which doubles as a cleaning cloth. Zeal Essential polarized sunglasses feature copper tinted lenses. Best fits medium faces.
Essential is the everyday work horse. It is best paired with your favorite pair of jeans. It rides shotgun on the long haul, with a look that is a blend of classic throwback combined with contemporary features that make it comfortable to wear anytime, anywhere.
