Okulary Frenzla

High accuracy in testing for spontaneous or provocation nystagmus is indispensable in present-day vestibular diagnostics. An examination for nystagmus using Frenzel spectacles is performed in a darkroom or a thoroughly darkened room. Frenzel spectacles have an internal illumination unit that cuts off the test person’s visual contact with the surroundings, eliminating any nystagmus-inhibiting fixation. Then the examiner can closely observe how the patient’s brightly illuminated eyes move under the spectacles’ magnifying lenses during forward gaze and diagnose any nystagmus.
