—I refute herein the claim that the Honey Bee Lens provides continuous magnification and that it increases the field of vision from 10° to 30° in each eye, providing a full 60° of magnification binocularly. Visual fields were plotted through the Honey Bee Lens at a distance of 6.6 ft (2 m) and 20 ft (6 m) for a person with normal vision, and at 20 ft (6 m) for a patient with nystagmus. These plottings showed that the field of the telescope was in fact discontinuous, extending laterally only 21° and including two blind spots totaling 4°. 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,
