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.

Attractive and works great. Be sure to clean the suction cups and sink before using!
Style: Scroll
I have wanted a sponge holder to put inside my sink for a while now. I wanted something attactive and I wanted it to work as it should. Seemed reasonable until I started looking and reading reviews. The biggest complaint appeared to be that these sponge holders do not stay attached to the sink. The reviews for this particular holder were great. Customers stressed cleaning the suction cups and sink before using. I am really glad they did because holder arrived in the packaging with zero instructions. Because I read the reviews I knew what to do and it worked! I am very pleased with this sponge holder. It is attractive, it feels really sturdy and it stays on the side of stainless steel sink just fine.

Pretty; sturdy; perfect size
Style: Contempo, Style: Contempo
Nice, sturdy little sponge and brush holder for the side of the sink. I was afraid my sink would me too small and spent lots of time trying to find a holder for the rim/countertop area. This one is not too big but fits my dobie and brillo perfectly. My sink is a little too short for a full fledged brush so when I tried to put in the brush I use sometimes it sticks up too much. That's really not the products fault so I won't subtract the score because of it. Also, I decided to put the holder flush against the side closest to me, instead of the side or the back of the sink. If I had chosen that location, the brush sticking out might not be an issue.

Yes the suction works on stainless steel!!
Style: Contempo
I've been through many rag holders before including a magnetic one, which broke. But the suction on this sucker (pun intended) is top notch! It doesn't slide around or come off or slide to the bottom of the sink. It just stays put which is so unique for anything with suction cups. The only reason i am giving it 4 stars instead of 5 is that it is quite small. I wish it were a few inches longer so i could easily fit two rags or sponges in the holder. But i have to jam them in and its not pretty. So for the price, i think it should have been bigger. Still a good product because of the functionality of the suction cups.

Absolutely Perfect
Style: Contempo
This is honestly one of my favorite kitchen purchases (which sounds silly) but it's AWESOME. There's a hole for my dish brush, which is so convenient and keeps it from draining anywhere else AND it has a nice ledge for my sponge. The suction was a little iffy at first, but once it really hunkered down, I've had it for a month and it hasn't fallen since the first day. I LOVE THIS

Great product once put on correctly.
Style: Contempo
When I first received it and placed it on, it continued to fall so I almost returned it. However, I found a method online that worked and it has not fallen since even after all the water and soap getting near it. I’ve placed it on a stainless steel sink so not sure if the method works on other surfaces. Clean the area with soap and water and then make sure there’s no soap residue. Make the water temperature hot and “heat up” both the steel surface and the suction. While it’s still wet, firmly place the suction and make sure it doesn’t move. That should do the trick!
