This spherical lens comes with our high-contrast XE2 technology with green or silver mirrored coating. The magnetic attachment mechanism allows for easy lens swapping.Product descriptionThe dual-layered, interchangeable XE2-lens is manufactured of a grade 1 optical quality polycarbonate which makes them both thin, lightweight, and practically unbreakable. They provide a high-contrast view, and the violet base secures enhanced colour recognition unveiling details normally invisible for the naked eye. With an XE2-lens, contrast-enhancing dyes are added to fine-tune the light spectrum and thereby increase contrasts and reduce glare, developed explicitly for snow sport and mountain conditions.
