Nystagmus Spectacles by Prof. Frenzel Type 502 with hinged lenses

The nystagmus spectacles according to Prof. Frenzel type 502 have foldable lenses, a fixed connection cable and a clip headband. When the lenses are turned up and the room lighting is switched on, eye observation with upright fixation is possible: e.g. the Hallpike technique of thermal examination. After switching off the room lighting and folding down the lenses, the changeover to the actual light spectacle examination can be started immediately without the need for fixation. Color of the glasses: black.

Modern vestibular diagnostics require high precision in the search for spontaneous or provocation nystagmus. The new nystagmus spectacles by Prof. Frenzel are an easy to use 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.
