A method for avoiding a tunnel vision of a motor vehicle driver includes detecting an instantaneous viewing direction of the driver; comparing the instantaneous viewing direction with at least one previous viewing direction; detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached; and stimulating the motor vehicle driver to avoid the tunnel vision. A device for avoiding a tunnel vision of the driver includes a camera for detecting an instantaneous viewing direction of the motor vehicle driver; a control unit for comparing the instantaneous viewing direction with at least one previous viewing direction and for detecting a tunnel vision if a rate of change between the viewing directions and/or if an angular range of the viewing direction is not reached, and a device for stimulating the motor vehicle driver to avoid the tunnel vision.
