Method for providing a display device for an augmented reality electronic information device intended to display to a user a virtual image superimposed on a real object, the virtual image having a parameter of predetermined value, the electronic information device including: - an optical element having a nonzero optical power and intended to be positioned in front of an eye of a user, the optical power depending on at least part of the user's prescription, - at least one sensor configured to determine the value of a parameter of the real object corresponding to the parameter of the virtual image, - a system for tracking the gaze direction of the eye of the user, the display device comprising a light source and a guide element having an intrinsic parameter, the guide element being intended to guide optical beams emitted by the light source to the eye of the user so as to allow viewing of the virtual image, the value of the parameter of the virtual image that is provided being equal to the value of the parameter of the real object seen through the electronic information device, which value is determined by the sensor, the display device furthermore comprising a second optical element having an optical power and intended to be passed through by the optical beams guided by the guide element to the eye of the user, the method including at least the following steps: - a step of providing a value of a parameter of the virtual image; - a step of determining an optimum value of a display parameter of the display device from at least one optical power at a point of the optical element, from the value of the parameter of the virtual image, and from the gaze direction of the user, so as to compensate the impact of the optical element on the virtual image; - a step of changing the display device in order to compensate the impact of the optical element on the virtual image, such that the perception of the real image and the perception of the virtual image are correct at the same time; - a step of providing a guide element having at least one parameter, called the unique intrinsic parameter, whose value is equal to the determined optimum value; and - a step of determining at least one optical power of the second optical element depending on the optimum value of the display parameter of the display device and on the value of the intrinsic parameter of the guide element. - an optical element having a nonzero optical power and intended to be positioned in front of an eye of a user, the optical power depending on at least part of the user's prescription, - at least one sensor configured to determine the value of a parameter of the real object corresponding to the parameter of the virtual image, - a system for tracking the gaze direction of the eye of the user, the display device comprising a light source and a guide element having an intrinsic parameter, the guide element being intended to guide optical beams emitted by the light source to the eye of the user so as to allow viewing of the virtual image, the value of the parameter of the virtual image that is provided being equal to the value of the parameter of the real object seen through the electronic information device, which value is determined by the sensor, the display device furthermore comprising a second optical element having an optical power and intended to be passed through by the optical beams guided by the guide element to the eye of the user, the method including at least the following steps: - a step of providing a value of a parameter of the virtual image;
