1. A method for displaying a computer generated image to a viewer via a stereoscopic display system, the method comprising: establishing a predetermined threshold distance from an eye of the viewer to a viewer perceived threshold displayed position of the computer generated image; determining that a vergence distance from the eye of the viewer to a viewer perceived current displayed position of the computer generated image is at or below the predetermined threshold distance, wherein the vergence distance is the distance between the eye of the viewer and a predetermined location associated with the image; and based on the vergence distance being at or below the predetermined threshold distance, increasing a size of the computer generated image while maintaining the vergence distance at the predetermined threshold distance as the eye of the viewer moves toward the viewer perceived threshold displayed position of the computer generated image.
