This is how it works

Involuntary eye movements ”Nystagmus”                                                                        

All the impulses of the sense of balance are linked to movements of the eyes. The most common and most important dizziness disorders can be detected or ruled out by assessing your eye movements – nystagmus analysis. Nystagmocatcher® is an optical attachment that you fasten in front of the camera lens of your smartphone. The attachment enables a high-definition video recording of your eye movements with your smartphone while simultaneously preventing the recorded right eye from being able to focus.


To provide clear diagnostic eye movements, it is very important that you cannot control or focus your gaze. During the examination, you should therefore close your left eye or cover it with the patch.
