Abstract of the Disclosure Conventional night vision goggles are provided with heads-up display information at the same focus and in the same field of view as the intensified image. The heads- up display information is typically generated by a remotely located cathode ray tube and transfered to the goggles by a fiber optic cable where it is then introduced into one of the eyepieces, which eyepiece is modified to include an image combiner placed inside its outer lens in order to provide substantially the same eye relief and physical dimensions as an unmodified eyepiece. The image combiner is a partially reflective mirror. Additional lenses are provided between the heads-up display and the beam combiner to insure that this additional information is presented to the eye at the same focus as the intensified image.
