Tusa Viewtrek Mask

The best way to increase the field of vision in a compact design is to shorten the distance between the lens and the eye. However, this has been limited by the narrowness of the area between the lenses because of the height of the bridge of the nose. In the M-23, the lenses have been spread apart, making it possible to get them closer to the eyes and to fit the nose skirt snugly into a thin frame between the lenses. Compared with conventional two-lens masks, the M-23 has double the field of vision. This design also allows convenient access to the nose for easier clearing of the ears. Moreover, the short distance between the lens and the eyes enables more accurate framing during underwater photography.
