The exceptionally low frame structure allows a great approach to the glass without contact problems with the mount. is reduced, therefore, the absolute minimum the internal volume and every vision frame is canceled from within. 15º inclined and extended above the cheekbones (a "Big Eyes") crystals increase visibility over the bottom 30% compared to a traditional mask, while the top and side visibility is increased to the extent that allows the own frame thickness: Total Vision - 3% for higher visibility and -5% overall vision side visibility.
It has been particularly studied the structural rigidity of the central bridge to prevent loss of the plane of the crystals due to an over voltage of the strip which could cause optical distortions.
The outer lip of the facial contact area face and lining the nose have a decreasing thickness enhancing adaptation and maintains comfort during long hours of use.
A note also buckles, fully swiveling in all directions and attached to the mount via a flexible and unbreakable elastomer. The tension of the strip acts directly on the frame to maintain the stability of the mask and approaching the maximum crystal eyes.
