Abstract:
A method is provided for aligning, without user interaction, the two images of a binocular eyewear display (100) with respect to their vertical, horizontal, and rotational orientation, and with respect to magnification. The method for aligning images comprise generating a signal from a display modification system (108) based on stored values indicative of misalignment of the binocular eyewear display (100); and adjusting, in accordance with the signal, an image or images to be displayed by an optics system (106). The stored values may include values for a plurality of temperatures and humidity.
