The Zeal Optics Tenacity Polarized Sunglasses feature ZB-13 lenses that let your squinting peepers relax. This lens color soothes your eyes and lets them adjust to changing light conditions. A polarized filter sandwiched between the ZB-13’s lens layers cuts horizontal glare from smooth pavement, water, and snow so you see better. The Tenacity’s comfortable, lightweight frames are durable, and nose and temple pads help these Zeal Optics sunglasses tenaciously stick to your face.
