The frameless design of the Axis features an elegant new quick-change system and a sleek shape. Two self-positioning magnets assist with the lightning-fast lens change, and four locking pins securely hold the lens in place. The medium size frame is suitable for a wide range of face shapes and offers an impressive wide EXV field of vision. The Axis includes two of the best lenses on the market with high-quality VIVID lenses from Zeiss Optics (one for sunny conditions, one for poorer weather conditions). Meanwhile, the EVAK ventilation technology and anti-fog coating keep moisture buildup under control.
