Optic Nerve Amino Multi Lens Sunglasses. Optic Nerve is certainly renowned for the exemplary fit and lens technology that make their sunglasses a favorite amongst cyclists, but now they've upped the ante even more regarding the issue of swapping lenses. The Optic Nerve Amino multi lens sunglasses feature proprietary SideSwipe technology that uses a small switch to make changing amongst any of the four included lenses super simple and with the minimum of handling. While very similar to the Optic Nerve Sequence glasses, the Amino's lenses are slightly taller. And of course, in addition to the aforementioned quartet of lenses, the Amino sports lightweight frames, adjustable temple tips, plus a lens coating designed to wick away pesky water, oil, and dust.
