Field Test: Because UV rays get stronger at elevation—and I live at 5,430 feet with 300 days of sun a year—I wear polarized shades daily. REVO’s Blue Water lens blocks 100 percent of UVA, UVB, and UVC rays, and cuts glare on the ski commute or when I sight fish. Lightweight acetate frames and anti-slip nose pads also work for bike commutes, shorter trail runs, and the skintrack.
Endurance factor: Scratch-free after four months of wear and drops. $189; revo.com —Olivia Dwyer
