Abstract

A binocular head mounted display system is shown utilizing an aspheric lens in each of the user's right-eye and left-eye optical paths. The aspheric lens is formed with a number of concentric zones for controlling the distance at which an image of displayed information is projected from the user and to minimize distortions across the virtual image. The distance between each lens and its respective display is independently variable. Further, the distance between the optical system as a whole and the user's eyes is variable.
