With the new LED-nystagmus spectacles we offer an improved version of our proven nystagmus spectacles according to Frenzel and Blessing.

Model 801 with headgear and connection cable is used for longer lasting examinations where the LED nystagmus spectacles are fixed to the patient’s head by means of the headgear, e.g. the examination for thermal testing of caloric nystagmus.

The actual lighted eyeglass examination takes place in a dark room or heavily darkened room. The interior illumination of the glasses interrupts the patient’s optical contact with his environment (elimination of nystagmus-inhibiting fixation). The illumination of the new LED nystagmus spectacles is provided by diodes arranged in a circle behind a luminous plate, which produce a diffuse light of adjustable brightness without any fixable luminous points affecting the examination result.

The timer function makes it easy to observe the deflections within a specified time period (30, 60 or 90 seconds).

For the cable versions of the LED Nystagmus Spectacles, the automatic on/off function can be deactivated. Here, one minute after the timer has expired, the illumination turns off; picking up the LED Nystagmus Spectacles again automatically turns them back on. This power saving feature, as well as a low-battery indicator, is designed to ensure the constant availability of the LED Nystagmus Spectacles.
