Modern vestibular diagnostics require high precision in the search for spontaneous or provocation nystagmus. In many cases a correct diagnosis can only be achieved by using the complicated technology of electron dust imaging (ENG). The new nystagmus spectacles according to Prof. Frenzel are an easy to handle alternative. The actual examination of the illuminated spectacles takes place in a dark room or a darkened room. The interior lighting of the spectacles interrupts the patient's optical contact with his surroundings (switching off the nystagmus-inhibiting fixation). At the same time, the brightly lit eyes under the magnifying lenses are particularly easy to observe. In many cases, pathological nystagmus processes can be detected when looking straight ahead, which are not or not reliably recognizable without glasses even when looking sideways.
