Keiichi Gray Calm-Tech

Made in Japan
Our performance eyewear system was developed over a two year technical testing period, involving New York City athletes and Japanese engineering. The frame features D+ lens technology, an adjustable hypoallergenic rubber nose pad and temple tips with a titanium core.

The Most Comfortable Sports Frame
Our hypoallergenic nosepad is mounted with titanium screws and a titanium core to produce the lightest, most comfortable sports frame. We recommend visiting a preferred optician to ensure a durable and comfortable fitting. Your sunglasses are accompanied by our highest grade 630GSM microfibre running pouch and ships in a Munken print 150g paper box.

Research & Development
District Vision researches and develops tools for outdoor pursuits. We have collaborated with athletes to produce the world's first proprietary Japanese eyewear system. With all our products, we maintain the methodology of Kaizen, the concept of continuous improvement, to make the finest tools for athletes.

A Porous Anti-Fog Lens
Calm–Tech is the world’s first porous lens that absorbs moisture, including fog and light rain droplets, to enhance visual clarity in challenging performance conditions. This proprietary polarized anti-fog lens was developed in Japan and tested with our team of athletes across the country over a period of two years. The technology is designed to reduce eye strain and contribute to a calmer training or race experience.

The Sports Lens of the Future
D+ lens technology is constructed from a proprietary form of polycarbonate, which is shatterproof. The lens interior features an anti-reflective application for holistic eye protection. The lens is finished with our oleophobic treatment making it water and oil repellent. Prescription lenses can be added to this frame.
