The best way of increasing the field of vision in a compact design is to shorten the distance between the lens and the eye. However, in the past this has been limited by the narrowness of the area between the lenses because of the height of the upper part 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 previous two-lens masks (e.g. the Splendive II), the field of vision is more than double. 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.

The field of vision comparison is obtained by an instrument that converts the measured light angles into a two dimensional map. The M-23, shown in red, has more that double the vision of most conventional products.
