CORRECTING DEVICE FOR EYESIGHT RECOVERY CAPABLE OF SETTING THE SHORT DISTANCE AND THE LONG DISTANCE IDENTIFYING MODE

摘要

PURPOSE: A correcting device for eyesight recovery is provided to simplify the structure of the correcting device by alternately setting the short distance and the long distance identifying mode. CONSTITUTION: The correcting device for eyesight recovery whose user alternately see the identified object at a long distance and the identified object at a short distance, includes; a marking unit of the identified object at a long distance, providing the identified object at a long distance; a marking unit of the identified object at a short distance, providing the marking unit of the identified object at a short distance; and a driving unit alternately setting the marking unit of the identified object at a short distance to a short-distance identifying mode, in which a long-distance identifying optical path between user's eye and the long-distance identified object is intercepted, or to a long-distance identifying mode, in which the optical path is opened.
