Operation
General
With the purchase of the nystagmus spectacle type 501/521 you have the opportunity to do an examination for which
the nystagmus spectacle remain for a longer time on the patient‘s head. The associated clip-head strap provides a
secure xation of the spectacle in front of the patient´s eyes and facilitates an easy search spontaneous and provoked
nystagmus e.g. through shaking the head, storing or examinations on swivel-chaires.
The 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 xation 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.
Use
• Clean the nystagmus spectacle with a soft cloth moistened with water and a mild, alcohol-free detergent before each
use. Then dry the glasses thoroughly with a soft dry cloth.

• Hold to the patient the nystagmus spectacle in front of the eyes over the nasal bridge.
• Place the clip-head strap over the patient‘s ears and around the back of the head.
• Make sure that the nystagmus spectacle do not shift during the examination. If necessary, tighten the clip- head
strap more tightly.

power supply type 506 (both not included).
