A method for distinguishing blinking events and instrument gazes on the basis of an eye-opening width. The eye-opening width represents an instantaneously detected clearance between the eyelids of an eye. In a step of ascertaining, a blinking event is ascertained using at least one blinking limit value. The blinking event is ascertained when an opening width value, which represents the eye-opening width, is smaller than the blinking limit value. In a step of determining, an instrument gaze is determined using a maximum blinking duration. The instrument gaze is determined when the detected blinking event is detected as lasting longer than the maximum blinking duration. The steps of the method are able to be carried out anew when the opening width value is greater than an open limit value following the determination of the instrument gaze.
