The Axis frameless design features a sleek new quick-change system and simple shape. Two self-positioning magnets make changing lenses lightning fast, and four snap-on pins hold the lens securely in the frame. The mid-size frame fits a wide range of face shapes and offers an impressively wide EXV field of view. The Axis features two of the best lenses on the market with high-quality VIVID lenses from ZEIss Optics (one for sunny conditions, one for less-than-ideal weather). While EVAK ventilation technology and anti-fog coating help control moisture build-up.
