Precision and protection: elevate your Snow Goggles with ZEISS Sonar Lenses.

In the world of winter sports, where speed, visibility, and precision define performance, choosing the right snow goggle lens can be a game-changer.

ZEISS Sunlens, a pioneer in optical innovations, introduces Sonar technology for snow goggles – an advanced solution designed to enhance contrast and clarity, helping athletes and enthusiasts alike navigate snowy landscapes with confidence.

Targeted towards snow goggle manufacturers, eyewear designers, and sports frame developers, Sonar goggle lens bring a new level of functional refinement and visual comfort to the slopes.

Snow-covered landscapes are stunning yet challenging, with unique lighting conditions that make it hard to “read” the environment. ZEISS Sonar technology addresses this by optimising contrast on highly reflective snowy surfaces. Using a specially developed spectral filter, Sonar lenses allow specific wavelengths of light to reach the eye, enhancing the contrast between snow and quickly recognize irregularities in the terrain, such as hummocks or hollows, icy sections or potential hazards, especially at high speed is key for the skier and snowboarder to react fast and avoid potential injuries.

The human visual system perceives snow as white, though its true colour is actually blue due to its reflection of the sky. The sky’s spectrum is dominated by blue light, making blue the primary colour reflected by snow. Blue light significantly impacts contrast vision, as its haze covers objects and reduces image clarity. To counteract this effect, many lens manufacturers now include "blue blocker" snow filters, the typical yellow lens, which filter out blue light to enhance contrast sensitivity.

ZEISS developed Sonar, a contrast-enhancing filter designed specifically to reveal details in the snow and improve depth perception. It allows certain wavelengths of blue light (380-420 nm) to pass through, helping the visual system better distinguish the contours and depth of uneven snow surfaces.

ZEISS Sonar lenses are crafted not only for enhanced vision but also with durability and safety in mind—vital features for high-performance eyewear in challenging, cold environments. Each lens undergoes rigorous testing to endure extreme weather and impacts, ensuring long-lasting functionality. Offering full UV protection, they guard against retinal damage from intense sunlight at high altitudes.
