Operation
General
With the purchase of the LED nystagmus spectacle type 803/823 you have the opportunity to do a short-term exami-
nation, in mobile use. The LED nystagmus spectacle is held directly in front of the patient‘s eyes, thus enabling a quick
uncomplicated search for provocation nystagmus,
e.g. by head shaking.
The LED nystagmus spectacle is equipped with strong refractive biconvex magnifying lenses with a power of +15 to
+18 diopters. They prevent a sharp vision and the fixation of objects. In this way, the patient‘s visual contact with
objects in the environment is interrupted, which would hinder the fast eye movements. At the same time the highly
illuminated eyes are easily observable under magnifying glasses.
