PILLA ZEISS Progressive is a proprietary lens technology engineered by PILLA and ZEISS. The lens science provides athletes with three distinct advantages: enhanced depth of field, increased color management, and live light management. This new lens concept introduces a variable color filtration as well as multiple filtration color curves in the same lens. This 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.
