The invention relates to an apparatus for measuring stereovision comprising: a frame body having a space therein; a 3D display unit which is arranged on the upper part of the frame body and which display a 3D image downwards through the space; a reflective mirror which is arranged on the lower part of the frame body and which reflects the 3D image displayed from the 3D display unit in a forward direction; an eyepiece which is arranged between the 3D display unit and the reflective mirror on the rear part of the frame body and through which a 3D image is seen; a half mirror by which the 3D image reflected forward by the reflective mirror is penetrated and reflected and which is rotatably installed on the frame body to adjust a reflection angle upward or downward; a stage which is arranged in front of the half mirror, a plurality of protrusion degree markers having a predetermined protrusion degree being arranged on the bottom surface successively with a predetermined distance, a target being installed on the stage to move forward, backward, left and right; and a target driving unit which moves the target forward, backward, left and right; wherein a reflection angle of the half mirror is adjusted such that an imaginary image of an object having a protrusion degree of 0 in the 3D image reflected on the half mirror is located above the protrusion degree marker having a protrusion degree of 0, the imaginary image being seen through the eyepiece; and wherein the target driving unit is controlled such that the target corresponds to an imaginary image of an object of a 3D image having a particular protrusion degree, whereby the stereovision of a tester is evaluated based on a protrusion degree marker to which the target is adjacent among the protrusion degree markers.
