Smith Embark Photochromic Sunglasses

Glacier-grade, photochromic shades that auto-tune to the light, kill glare off snow, and stay welded to your face from skintrack to summit ridge.

The Smith Embark Photochromic Sunglasses are purpose-built glacier glasses for skiers, splitboarders, and mountaineers who are out in big, bright terrain all day. Their ChromaPop™ Glacier Photochromic lens is activated by UV and visible light, shifting smoothly from about 45% to 7% visible light transmission so you can go from flat-light approaches to full bluebird exposure without swapping lenses. ChromaPop™ tech runs through the entire tint range, boosting contrast to make every wind drift, sastrugi line, and crevasse feature stand out more clearly while reducing eye fatigue. Removable, ventilated TPU side shields and a snow-goggle inspired retainer strap give you goggle-like coverage and security on exposed faces, while the medium-fit Evolve™ bio-based frame, QuickFit adjustable temples, Megol nose pads, and 6-base curve keep things comfortable and stable for long days in the hills. If you’re stacking big vert in harsh alpine light, these are the glasses you want in your kit.

• Glacier Photochromic lens: UV and visible light-activated ChromaPop™ Glacier Photochromic lens adapts from 45% to 7% VLT for clear vision from dawn approaches to full midday glare.
• High-contrast ChromaPop™ optics: Contrast-boosting tech sharpens detail in snow, rock, and ice so you can read terrain features and hazards more confidently at speed.
• Serious side coverage: Removable, ventilated TPU side shields block harsh peripheral light and reflection off the snowpack while still allowing airflow to help manage fog.
• Secure alpine fit: QuickFit adjustable temples, AutoLock hinges, and Megol nose and temple pads keep the frame planted on your face during technical ascents and sketchy descents.
• Durable, lightweight frame: Evolve™ bio-based frame material is tough, light, and built to handle crampons in the pack, rope tangles, and general expedition abuse.
• Goggle-style retention: Included snow-goggle inspired retainer strap adds extra security so you’re not watching your sunnies tomahawk down a couloir if they get bumped.
