Dual-layer technology
VALLON Freebirds™ and Stairways™ feature best-in-class dual-layered lens technology from leading optics specialists, Carl ZEISS, and Mazzuchelli.
Both models feature composite lenses made with two respective layers - an outer lens designed using ZEISS impact-resistant 1.6mm polycarbonate shield technology, and an inner anti-fog lens from Mazzuchelli.
SHAPE
Sphere or Cylinder
Freebirds™ have spherical lens from ZEISS, giving the ultimate field of vision.
Stairways™ have a cylindrical lens from ZEISS, giving excellent peripheral vision.
BLUE LIGHT
Attenuation
ZEISS’ Sunlens development team undertakes extensive on-field research focussing on the impact of blue light on optical performance during skiing and snowboarding.
Some blue light is needed (in the range of 400-420nm) to help our eyes perceive contrast and definition on snow and ice. ZEISS’s SONAR technology allows only the pure blue light to pass through, suppressing the ‘blue haze’ effect.
READY FOR ALL CONDITIONS
Interchangeable lenses
No single lens will cover you for all weather conditions whilst skiing and snowboarding, which is why we offer interchangeable lenses for our ski and snow goggles.
COLOR
Performance tint
Lens tint and coating colors are important for optimising vision in different light conditions experienced in the mountains. We advise that you think about the conditions you are likely to encounter, and buy a couple of lenses to match.
