Lenses Sunglasses 101: Glass is clearest and most resistant to scratching, but it can shatter, so most sports brands opt for plastic. Vuarnet, however, is using a proprietary chemical tempering to strengthen its glass lenses. Our sample survived a season of hard testing—including ski-touring, mountaineering, and dog-sledding—winning our confidence. We liked the blue lenses with gold mirrors for snowy pursuits.
Frames A redesign of Vuarnet’s original model from the 1950s, the 02 frame features the same large, circular lenses and skinny temples that worked for Mick Jagger. Gripe: There’s no rubberized nosepad, so they slipped when we got really sweaty.
