The frameless design of the Axis has an elegant quick-change system and a simple shape. Two self-positioning magnets support lightning-fast lens changes and four pins with snap-in function hold the lens securely in the frame. The medium size frame is suitable for a wide range of face shapes and offers an impressively wide EXV field of vision. The Axis includes two of the lenses on the market with high quality Vivid lenses from Zeiss Optics (one for sunny conditions, one for poorer weather conditions). While the Evak ventilation technology and anti-fog coating keep moisture build-up under control.
