PILLA ZEISS Ice Progressive is a proprietary lens technology engineered by PILLA and ZEISS utilizing both Chromashift and Infra Red lens science. The lens science provides athletes with three distinct advantages over the standard Ice Lens offering: enhanced depth of field, increased color management, and “live light” management. This new lens design introduces a variable color filtration as well as multiple filtration color curves in the same lens. Our new lens design with Chromashift IR focuses the variance in a narrower band of spectral color curves. From our original design to this new version the amount of change from top to bottom of the lens has been reduced. This new variation in filtration and light transmission allows the eye to perform at its maximum focal potential while allowing for variable filtration saturation. The result is crisp vision at distance, rich definition of the sight picture, and the ability for the wearer to change transmittance to tune resolution immediately depending on where you look through the lens.
