When the sun strikes mercilessly on snowfields, ordinary sunglasses become traitors to your vision
The Glacier Vision Crisis
High-altitude athletes know the cruel arithmetic of snow glare: fresh snow reflects up to 90% of UV radiation – nearly double water’s reflectivity. Standard cycling sunglasses, even premium models, fail catastrophically in these conditions through three fatal flaws:
- Peripheral light leakage creating blinding “side attacks”
- Fixed-frame designs that can’t accommodate mountaineering helmets
- Lens technology optimized for forest trails rather than crystalline snowscapes
The consequences aren’t merely discomfort – snow blindness and accelerated eye fatigue directly impair decision-making in technical terrain. POC’s Devour Glacial redefines extreme light conditions eyewear through Swedish avalanche research and Zeiss optical science.
Three-Layer Defense Architecture
Physical Fortification
- 3D-printed eye shields extending 8mm beyond standard frames
- Triple-axis adjustable temples with silicone grip zones
- Magnetic lens interchange system (3-second swaps)
- Ventilated brow bar preventing fog buildup
Optical Warfare System
- Zeiss Clarity lenses with blue light filtration algorithm
- Dynamic contrast enhancement for shadow definition
- UV400 full-spectrum protection
- Ri-Pel nano-coating repelling ice crystals
Adaptive Biomechanics
- Pressure-mapping technology across 12 facial zones
- Cold-weather optimized materials (-30°C rating)
- Helmet-compatible without goggle overlap
- No-slip silicone at all contact points

From Snow Blindness to Crystal Vision
The Crisis
Sarah, backcountry guide, loses critical depth perception during a glacial traverse. Her premium sunglasses fail to block reflected glare from all directions.
The Breakthrough
Testing Devour Glacial, she immediately notices the side shields eliminating peripheral glare attacks. The adjustable nose piece accommodates her goggles perfectly.
The Transformation
During an emergency crevasse rescue, Sarah spots subtle snow texture variations through Zeiss lenses that reveal hidden weak snow bridges – impossible with her old eyewear.
Why Glacier Professionals Choose POC
For Backcountry Skiers
The interchangeable lens system allows rapid adaptation from morning flat light to midday glare. Testers report 37% less eye fatigue during 8-hour tours compared to fixed-lens alternatives.
For Ice Climbers
When leading WI5 routes, the anti-fog ventilation maintains critical visibility during strenuous sections. The Ri-Pel coating sheds ice chips that would obscure vision in standard glasses.
For Expedition Guides
During 30-day Denali expeditions, the UV400 protection prevents cumulative eye damage. The cold-weather materials remain flexible when competitors’ frames become brittle.
For Glacier Researchers
Studying subtle ice formations requires Zeiss Clarity definition. The blue light filtration enhances contrast to reveal cryoconite patterns invisible through standard lenses.
Vision Redefined at $85.99
In high-stakes alpine environments, compromised vision isn’t an option. The Devour Glacial represents five years of Swedish avalanche safety research distilled into eyewear that performs when the mountains demand absolute clarity.
