Zeal Optics Avon

Thanks to its comfort and functionality, the Avon quickly became our jack-of-all-trades for a full season of outdoor multisporting. Polarized lenses filter out 95 percent of destructive, high-energy blue light wavelengths (the only lenses in the test to do so), which improves depth perception and gave us the confidence to charge down boulder-strewn trails in Colorado’s Eldorado Canyon State Park in variable light conditions. The Avon’s plant-based bioplastic lenses boost contrast in low light, thanks to a copper tint (also available in dark gray and blue for sunnier days): “I’m normally a compulsive on-and-off changer of sunglasses because I feel like I can’t see the trail well enough when it’s shady,” said one tester after a run near Brainard Lake, Colorado. “But these lenses remained sharp through shifting conditions, including sun, clouds, and even hail.” Rubber nosepads and temple grips helped the Avon stay put on sweaty trail runs, and we didn’t have problems with fogging on cool days.
