Get a sudden boost of speed and clarity when you run with Optic Nerve's Polarized Vahstro Sunglasses. Their SideSwipe interchangeable system lets you change the included lenses at a quick flip of a switch. Each polarized lens blocks obnoxious glare, and a hydrophobic coating wicks away water, oil, and dust. The lenses also provide 100% UV protection and meet ANSI Z80. 3 standards for clarity and resistance. Optic Nerve paired these lenses with a highly durable TR90 frame, and the frame's nose and temples feature non slip, triple injected rubber for a stay put fit.
