Other disadvantages of the Honey Bee Lens are chromatic distortion, internal reflections, blurred images in the left and right telescopes, the impossibility of adding a spectacle correction, and the unsuitability for close vision.
Since October 1981, even before its presentation at a scientific meeting or publication in professional literature,
