What do you get when you combine two years of technical testing on athletes with impeccable Japanese engineering? You get the world’s first proprietary Japanese eyewear system. District Vision researches and develops sunglasses for running. They create products that are both functional and performance enhancing. And with their Nagata D+ Black Rose sunglasses, they have created an advanced sports lens engineered for trail running and physical pursuits that involve changing light conditions.

What exactly does that mean? Glad you asked. The lens has a variable light transmission allowing 15.6% to 35.15% of light through, which enhances visibility in a variety of performance conditions. The D+ lens technology is constructed from a proprietary form of polycarbonate material, which makes them shatterproof and scratchproof. The lens interior features an anti-reflective application for holistic eye protection. And the lens is finished with their oleophobic treatment making it water and oil repellent. So basically these things are unstoppable. Oh, did we mention the hypoallergenic nosepad mounted with titanium screws and a titanium core for the most personal fit? If you’re a serious runner, you’re going to want to add these to your wishlist immediately.
