Ahead of this year’s Rio 2016 Summer Olympics, Nike Vision and the optical craftsmen at Zeiss teamed up to craft the perfect mix of form and performance for their Running 2016 collection. This was a complete ground-up build that saw the duo starting from scratch to manufacture a new lens from a custom mold. The mold was then refined using unparalleled precision and diamond-polishing technology to polish the complex lens shape down to the nanometer. In the end, we get a lightweight lens that delivers maximum coverage and optimum clarity to the athletes wearing them. The 5-piece collection is available now, while you can check out a behind-the-scenes look at the manufacturing process in the video above.
