ABSTRACT:
Aperture stops are positioned in the optical train of a partially overlapped binocular display in a such a manner that overlapping portions the binocular boundaries of the left and right fields of view are substantially out of focus, and therefore do not appear as well defined, distracting contours in the visual field. The present invention is particularly well suited for use in virtual reality systems employing head mounted displays.
