As shown in fig. 1, the apparatus 10 includes a left-eye display screen 13 as a left-eye near-eye display module and a right-eye display screen 14 as a right-eye near-eye display module, wherein the left-eye display screen 13 and the right-eye display screen 14 can independently display a light spot at a specified position. The device 10 also includes a handle 12 operable by a user, by which control of the location of the light point is achieved. Further, the apparatus 10 further includes a processing unit 11 connected to the handle 12, the left-eye display 13, and the right-eye display 14, respectively, so that the user can change the positions of the light spots displayed in the left-eye display 13 and the right-eye display 14 via the processing unit 11 by operating the handle 12 and perform corresponding recording.
First, the device 10 is worn in front of the eyes of the user so that the centers of the left-eye display 13 and the right-eye display 14 are aligned with the centers of the visual fields of the left eye and the right eye of the user, respectively, and the center mark points thereof are displayed, respectively.
As shown in fig. 2a and 2b, after the user wears the device 10, the left-eye correction position and the right-eye correction position displayed on the left-eye display screen 13 (shown in fig. 2 a) and the right-eye display screen 14 (shown in fig. 2 b) are compared with the standard position by the binocular disparity judging method of the present invention.

And then, calculating according to the left eye correction position and the right eye correction position of each group to obtain a correction matrix. For example, for a standard position, the left eye correction position is (x)1,y1) The right eye correction position is (x)2,y2) Then, the correction matrix is represented by (x)2-x1,y2-y1). The other points are as above。
