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 with adjustable brightness without any fixable luminous points that could affect the examination result. The timer function makes it easy to observe the deflections within a specified time period (30, 60 or 90 seconds).<\/p>\r\n<p>For the cable versions of the LED nystagmus glasses, 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 function, as well as a low-battery indicator, is designed to ensure the constant availability of the LED Nystagmus Spectacles.<\/p><\/div>\n<div id='slider_1011_slide02' class='sa_hover_container' style='padding:5% 5%; margin:0px 0%; '><p>The scope of delivery of the LED Nystagmus Spectacles includes:<\/p>\r\n<div class=\"prod-grid\">\r\n<div class=\"prod-pic\"><img loading=\"lazy\" decoding=\"async\" class=\"alignleft wp-image-1357 size-medium\" src=\"https:\/\/dehag.com\/wp-content\/uploads\/2023\/05\/821_LED-Nystagmusbrille_TYP-821_10x10cm-1-300x300.jpg\" alt=\"\" width=\"300\" height=\"300\" srcset=\"https:\/\/dehag.com\/wp-content\/uploads\/2023\/05\/821_LED-Nystagmusbrille_TYP-821_10x10cm-1-300x300.jpg 300w, https:\/\/dehag.com\/wp-content\/uploads\/2023\/05\/821_LED-Nystagmusbrille_TYP-821_10x10cm-1-1024x1024.jpg 1024w, https:\/\/dehag.com\/wp-content\/uploads\/2023\/05\/821_LED-Nystagmusbrille_TYP-821_10x10cm-1-150x150.jpg 150w, https:\/\/dehag.com\/wp-content\/uploads\/2023\/05\/821_LED-Nystagmusbrille_TYP-821_10x10cm-1-768x768.jpg 768w, https:\/\/dehag.com\/wp-content\/uploads\/2023\/05\/821_LED-Nystagmusbrille_TYP-821_10x10cm-1-600x600.jpg 600w, https:\/\/dehag.com\/wp-content\/uploads\/2023\/05\/821_LED-Nystagmusbrille_TYP-821_10x10cm-1.jpg 1181w\" sizes=\"(max-width: 300px) 100vw, 300px\" \/><\/div>\r\n<div class=\"prod-txt\"><strong>1x LED Nystagmus Spectacles Type 821<\/strong> with improved stability and processing quality.
