"Full Description:\nGlacier travel. High elevation summits. Spring snowfields. Eye protection in the alpine is serious business. Whether you're skiing or mountaineering, the Smith Embark sunglasses hold up to harsh, ever-changing conditions while providing a contrast-boosting view of every crevasse, wind drift and terrain feature. <br><br>The UV and visible light activated Glacier Photochromic lens is less temperature sensitive than a traditional photochromic lens with a light transmission range from 45% to 7% that adapts dynamically to variations in light. ChromaPop™ delivers color and contrast-boosting performance throughout the full range of the lens, so you always have the best possible view. Removable and ventilated side shields add peripheral light coverage, and low-profile, adjustable temple arms let you customize the fit. A goggle-inspired retainer strap adds the security to keep them in place through technical ascents and high-speed descents.\n\nFeatures:\n\u003cul>\n\u003cli>Vision\u003c/li>\n\u003cli>VISION: Available in your choice of ChromaPop™ Glacier Photochromic Copper Blue Mirror or ChromaPop™ Polarized lenses; ChromaPop™ Glacier Photochromic lens tint adapts to match the light conditions with less sensitivity to temperature changes and full ChromaPop™ contrast and color enhancement throughout the tint range; Anti-fog and hydroleophobic coatings on the Glacier Photochromic lenses for clear optics and easy cleaning; ChromaPop™ Polarized lenses cut glare and enhance color and contrast; FIT/INTEGRATION: Easy-adjust QuickFit temples for a customized fit; AutoLock hinges hold frames open for easy one-hand on and off; 6-base lens curvature offers a modest wraparound fit; Megol temple and nose pads provide non-slip grip so glasses stay put; FRAME: Evolve™ bio-based frame material is lightweight and durable; INCLUDED: Removable TPU side shields block peripheral light; Snow goggle inspired retainer strap; Microfiber bag and hard case\u003c/li>\n\u003cli>6-base lens curvature offers a modest wraparound fit\u003c/li>\n\u003cli>Fit/Integration\u003c/li>\n\u003cli>Anti-fog and hydroleophobic coatings on the Glacier Photochromic lenses for clear optics and easy cleaning\u003c/li>\n\u003cli>ChromaPop™ Glacier Photochromic lens tint adapts to match the light conditions with less sensitivity to temperature changes and full ChromaPop™ contrast and color enhancement throughout the tint range\u003c/li>\n\u003cli>Available in your choice of ChromaPop™ Glacier Photochromic Copper Blue Mirror or ChromaPop™ Polarized lenses\u003c/li>\n\u003cli>Megol temple and nose pads provide non-slip grip so glasses stay put\u003c/li>\n\u003cli>Anti-reflective coating improves clarity and reduces eye strain (ChromaPop™ option only)\u003c/li>\n\u003cli>Smudge and moisture resistant coating for easy cleaning and clear optics (ChromaPop™ option only)\u003c/li>\n\u003cli>Carbonic lenses offer impact resistance and clear optics\u003c/li>\n\u003cli>AutoLock hinges hold frames open for easy one-hand on and off\u003c/li>\n\u003cli>Evolve™ bio-based frame material is lightweight and durable\u003c/li>\n\u003cli>Frame\u003c/li>\n\u003cli>ChromaPop™ lenses enhance contrast and natural color to make the details pop\u003c/li>\n\u003cli>100% UV protection\u003c/li>\n\u003c/ul>\n\nSpecifications:\n\u003cul>\n\u003cli>What's Included\u003c/li>\n\u003cli>Removable TPU side shields block peripheral light\u003c/li>\n\u003cli>Snow goggle inspired retainer strap\u003c/li>\n\u003cli>Microfiber bag and hard case\u003c/li>\n\u003cli>Medium fit, large coverage\u003c/li>\n\u003cli>Megol nose pads provide nonslip grip so glasses stay put\u003c/li>\n\u003cli>6-base lens curvature offers a modest wraparound fit\u003c/li>\n\u003cli>Lens Width: 58mm Lens Height: 45mm Temple: 145mm\u003c/li>\n\u003c/ul>\n"
