Abstract

The perforation glasses include ears and an ophthalmologic rim to which non-transparent disks with perforated rasters are attached. The holes in these rasters are made of a strictly circular conical form with the direction of the bigger cone base towards the light source, and have a diameter that ensures the acquisition of the interference figure in the form of dark and light rings of light diffusion. The rings alternate across the whole section of a light ray that passes through the hole. The holes in the raster placed hexagonally with distances between their centers from all directions that ensure the overlapping of interference figures by the rings of the same kind – dark or light ones. Moreover, the holes in the raster have a different diameter which changes by vertical lines. The holes of the maximum diameter may be placed from above or from below of the raster depending on the refraction anomaly. In the non-transparent disks fixed on the ophthalmologic rim by mobile spherical joints that ensure the possibility to change a location and a spatial orientation of disks, segments from the direction of the holes of a bigger diameter are eliminated.
