Product Description

LED Frenzel Glasses

The LED Frenzel glasses from DeHag is the next generation of nystagmus goggles. The LED technology guarantees nearly lifelong functionality of the light source. The LED light glasses are used to examine the vestibular organ and to detect eye movement disorder (nystagmus). Frenzel glasses are also known as nystagmus goggles.


The Frenzel glasses test is used to detect so-called spontaneous nystagmus, which is often related to a disturbance of the sense of balance. Eye tremor is often associated with neurological, ophthalmological and ENT disorders. Other symptoms include spinning and staggering vertigo, blurred vision and double vision. The easy handling of these LED nystagmus goggles makes it possible to quickly detect an eye movement disorder.


The examination should always take place in a darkened room so that the LEDs illuminate the patient's eyes in the best way possible. The nystagmus goggles are equipped with two magnifying lenses with a power of at least +15 dpt. Looking at surrounding objects can interfere with eye movements, making diagnosis more difficult. The high magnification of the lenses as well as the illumination on the one hand prevent fixation on surrounding objects and on the other hand allow easy viewing of eye movements. This way, the nystagmus-inhibiting fixation is switched off.


The timer function allows observation within a certain period of time (30, 60 or 90 seconds). In addition, the LED Frenzel glasses switch off automatically 1 minute after the timer has expired and switch on again automatically when the instrument is put on again.


The LED Frenzel glasses are available in two models. The model type 823 is equipped with a fixed battery handle. The power supply of the Frenzel glasses type 821-A is provided by a connection cable, connected to a lithium ion battery including charging cradle. The battery switch housing is used to control the function of the nystagmus goggles. It enables work independent of the mains supply and facilitates handling, for example, during swivel chair and positioning examinations. The constant availability of the Frenzel glasses is ensured by the battery switch housing. The clip headband for fixing the LED nystagmus goggles is already included in the scope of delivery of this model.
