An image is displayed by smartglasses, the image being at least partly superimposed on a real environment of the smartglasses when the real environment is viewed through the smartglasses. In this case, the image represents an image of the real environment which is recorded by a night-vision image-recording device. The image is displayed in such a way that an image object in the recorded image, which corresponds to a real object arranged in the real environment, is displayed in the image in a manner overlapping the real object in the real environment. In the dark and in the event of poor visibility, potential hazards can be perceived significantly better by virtue of the night-vision images in order that additional driver-assisting information is provided and traffic safety is increased.
