CTRL ONE Smart Sunglasses
Slow-changing transition lenses are one thing. The technology in CTRL ONE Smart Sunglasses, another. Originally developed for the U.S. military, CTRL ONE uses Tint-on-Demand tech within its lenses that switches from crystal clear to dark at the push of a button and in less than one tenth of a second. The lenses themselves meet ANSI Z87.1 standards for ballistic protection against rubble and offer 100% UV protection, as any good sport shades should. They also boast adjustable nose and temple pads for customizing your fit, last for about 50 hours of continuous use, and feature an automatic mode where an integrated light sensor decides what tint is most appropriate for current conditions.
