Abstract

"Indicator device for graduation of the interpupillary distance in the twins", characterized essentially by its easy adaptation to the twins, especially with pins, which allows to vary the distance between the axes of the glasses, consisting of a metal sheet (Fig. 2) with a central hole where the telescope is housed, one end of which constitutes the axis of rotation on the support, while the opposite one slides on a graduated limb indicating in m/m the interpupillary distance (Figure 1).
