The Yusuke Alpine Blade Ti is a six-base blade style proprietary sunglass system featuring a frame composed entirely of lightweight and durable aerospace-grade titanium. The frame features custom anodized titanium hardware, hypoallergenic rubber nose pads and temple tips for a fully customizable fit, and utilizes our signature D+ therapeutic grade lenses, constructed from a proprietary form of shatterproof polycarbonate. The lens shaping draws inspiration from early alpine and explorer eyewear, where the lens acted as a protective shield for the eyes and face. The lens interiors are treated with both anti-reflective and oleophobic coatings for holistic eye protection and water and oil repellency. The D+ Onyx Mirror was developed for physical pursuits that require maximum sun protection. The mirror coating facilitates additional infrared screening. The lens offers 100% UVA/B protection while transmitting 16.19% of visible light and 15.99% of blue light.
