The bayonet connection and the different connection cables allow a quick conversion of the nystagmus goggle into a nystagmus goggle suitable for all examination forms. For example for positioning or swivel chair examinations. By ordering the right components, a nystagmus spectacle can be assembled to meet the individual needs of the doctor. The actual illuminated spectacle examination takes place in a dark room or in a heavily darkened room. The internal illumination of the spectacles breaks the optical contact of the patient with his surroundings (elimination of the fixation that prevents nystagmus). At the same time, brightly illuminated eyes are particularly easy to observe under magnifying spectacles. In many cases, abnormal nystagmus processes can be detected by looking straight ahead which cannot be detected reliably or at all without glasses, even when looking sideways. The power supply for the nystagmus spectacles is provided by the battery-powered handle type 7.03.04. The nystagmus goggle can be optionally equipped with a bayonet cable type 7.03.05 and a battery holder type 7.03.04 or a connecting cable type 7.03.05 and a battery holder type 504 and a battery holder type 7.03. The cable, battery holder, plug-in power supply and clip-on headgear are not included. The battery holder handle and battery holder housing are powered by three 1.5 volt LR14/AM-2 batteries, each of size C, 1.5 volt (baby batteries). The adjustable battery handle allows the brightness to be adjusted individually by turning the switch slightly. The pluggable power supply can be connected via a standard household socket (100-240V/AC, 50/60Hz).
