Zusammenfassung:An optometric testing device comprising a first shutter and a second shutter placed in front of two eyes of a patient and configured to present an activated state in which a shutter blocks the propagation of light and a deactivated state in which the shutter allows the propagation of light, a communication unit configured to communicate with a display system in order to send and/or receive a synchronization signal, and a control unit configured to command each shutter as a function of the synchronization signal so that the first shutter and the second shutter change state with a first frequency and a second frequency, wherein the control unit is configured to command each shutter so that the first frequency is different from the second frequency and/or so that a duty cycle of activation of the first shutter is different from a duty cycle of activation of the second shutter.
