Berlin-based Mykita and the German optics manufacturer Leica have entered a collaboration to produce sunglass models with high-precision lenses. The collection comprises a stainless-steel-only range and a line that combines stainless steel with Mykita’s 3D printed material, Mylon. The lenses feature AquaDura Vision Pro, an achromatic anti-reflective coating providing protection against rear reflections, fogging and fingerprints.
