The bayonet coupling and the various connection cables allow the quick conversion of nystagmus spectacles into nystagmus spectacles 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 7.23.04. Optionally, the nystagmus goggle can be equipped with a bayonet cable type 7.23.05 and a battery holder type 7.23.04 or a connector cable type 7.23.05 and a battery holder type 504 and a battery holder type 7.23.04. 05 and 506 plug-in power supply (cable, battery holder, plug-in power supply and clip-on headband not included). The battery handle and battery housing are powered by three CLR14/AM-2 batteries (baby batteries) of 1.5 volts each. The adjustable battery handle allows the brightness to be adjusted individually by turning the switch slightly. The plug-in power supply is connected via a standard household socket (100-240V/AC, 50/60Hz). It works with two 4-volt lamps, which can be purchased separately.
