A method and apparatus for reducing the magnitude and edge clarity of the luminosity of an undesired image of a external object reflected from a portion of a surface of a visual display into the eye of a user includes placing a cover in the path of the reflected image. The cover has a surface portion which is not parallel to the portion of the surface of the display. As result the reflections from the cover and from the display surface portions provide multiple images of the external object to the user each having a luminosity magnitude which is less than the magnitude of the luminosity of the undesired image that would occur if the cover was parallel to the display surface portion thereby resulting in super-imposed images.
