发明名称 RETRACTABLE EYESHIELD
摘要 RETRACTABLE EYESHEILD A retractable, partial eyeshield assembly is attached to a single eye sighting device attached to, for example, a video camera. The partial eyeshield assembly is constructed so that it covers a portion of the medial field of view of the user's nonsighting eye. The obstructed portion of the nonsighting eye's medial field ofview corresponds to that portion of the sighting eye's that contains only the image transmitted through the single eye sighting device's sighting aperture. By obstructing the portion of the nonsighting eye's medial field of view, the corresponding field of view in the sighting eye dominates. The obstruction of the portion of the nonsighting eye's field of view is achieved without obstructing asubstantial portion of the nonsighting eye's peripheral and medial fields of view.
