Product description

Evaluating eye movements in darkness, namely nystagmus, is essential for diagnosing several clinical syndromes. However, eye-fixation most often inhibits these eye movements and difficults a correct diagnostic.
The μFrenzel® Video Goggles - Medical video goggles allows precise, real time, positional visualization of eye movements in complete darkness.
