ABSTRACT:
A partial eyeshield is attached to a sighting device, for example a video camera. The eyeshield is constructed so that it covers a portion of the field of view of the user's nonsighting eye. That portion of the nonsighting eye's field of view corresponds to a portion of the field of view of the sighting eye the user desires to view without closing his nonsighting eye. So covering the nonsighting eye causes the corresponding field of view in the sighting eye to dominate, while leaving substantial usable vision through the nonsighting eye.
