The LED technology \u003cb\u003eguarantees nearly lifelong functionality of the light source. \u003c\/b\u003eThe 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.\u003c\/p\u003e\u003cbr\u003e\n\u003cp\u003eThe Frenzel glasses test is used \u003cb\u003eto detect so-called spontaneous nystagmus\u003c\/b\u003e, 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. \u003c\/p\u003e\u003cbr\u003e\n\u003cp\u003eThe 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 \u003cb\u003eequipped with two magnifying lenses with a power of at least +15 dpt.\u003c\/b\u003e 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.\u003c\/p\u003e\u003cbr\u003e\n\u003cp\u003eThe\u003cb\u003e timer function \u003c\/b\u003eallows 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.\u003c\/p\u003e\u003cbr\u003e\n\u003cp\u003eThe LED Frenzel glasses are available in two models. The model \u003cb\u003etype 823 is equipped with a fixed battery handle\u003c\/b\u003e. \nThe power supply of the Frenzel glasses\u003cb\u003e type 821-A is provided by a connection cable, connected to a lithium ion battery including charging cradle\u003c\/b\u003e. 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.\u003c\/p\u003e\u003cbr\u003e\n\n\u003ch3\u003eProduct Details\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eLED Frenzel glasses\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eFor recognising a nystagmus (spontaneous and provoked nystagmus)\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003eDioptre strength of at least +15 dioptres\u003c\/li\u003e\n\u003cli\u003eFirm lenses\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003e3 LED light diodes for optimal illumination\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003eNearly lifelong durability of light source\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eContinuously regulable brightness\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eAvailable in 2 models: type 823 with battery handle; type 821-A with power cable\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003eAutomatic on\/off function\u003c\/li\u003e\n\u003cli\u003e\u003cb\u003eTimer function optionally settable to 30, 60, 90 seconds\u003c\/b\u003e\u003c\/li\u003e\n\u003cli\u003eTempered lenses\u003c\/li\u003e\n\u003cli\u003eWhite housing\u003c\/li\u003e\n\u003cli\u003eManufacturer: DeHag\u003c\/li\u003e\n\u003c\/ul\u003e\u003cbr\u003e\n\n\u003cdiv class=\"c-text__table\"\u003e\u003ctable style=\"width: 100%; border-collapse: collapse\" cellspacing=\"0\" cellpadding=\"3\" bordercolor=\"#000000\" border=\"1\"\u003e\n\u003ctbody\u003e\n\u003ctr valign=\"top\"\u003e\n\u003cth scope=\"col\" width=\"33%\"\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003c\/th\u003e\n\u003cth scope=\"col\" width=\"33%\"\u003e\nPower Supply \u003c\/th\u003e\n\u003cth scope=\"col\" width=\"33%\"\u003e\nAttachment \u003c\/th\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd\u003e\n\u003cstrong\u003eFrenzel Glasses type 821-A\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\nPower cable with rechargeable battery in switch housing and charging station \u003c\/td\u003e\n\u003ctd\u003e\nIncludes latching headband\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr valign=\"top\"\u003e\n\u003ctd\u003e\n \u003cstrong\u003eFrenzel Glasses type\u003c\/strong\u003e\u003cstrong\u003e 823\u003c\/strong\u003e\n\u003c\/td\u003e\n\u003ctd\u003e\nAttached battery handle\nRequires 3 batteries (not included in delivery)\u003c\/td\u003e\n\u003ctd\u003e\nWithout latching headband; battery handle serves as handle\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003c\/div\u003e\u003cbr\u003e\n\n\u003cp\u003eOrder the LED Frenzel glasses and other nystagmus goggles with matching accessories at a reasonable price from Orange Medical. \u003c\/p\u003e","brand":"Orange Medical","offers":[{"title":"Default Title","offer_id":51895377035591,"sku":"136529","price":852.22,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0905\/6301\/9079\/files\/136529_led_nystagmus-brille_typ_832_web_bdaa4b79-e140-45ca-8fbd-b1047329ab2f.jpg?v=1752053962","url":"https:\/\/orangemedical.co.uk\/products\/led-frenzel-glasses","provider":"Orange Medical","version":"1.0","type":"link"}
