The vision produced when both eyes see an object is called binocular vision. When two eyes look at objects, a complete object image is formed on the retinas of the two eyes, and due to the fine coordinated movement of extraocular muscles, light rays from the same part of the object can be imaged on symmetrical points of the retinas of the two eyes, so that the vision of a single object is subjectively generated, and the vision is called single vision. Paralysis of the extraocular muscles or compression of tumors within the eye, etc., can cause the object image to fall on the asymmetric points of the retinas of both eyes, thus subjectively creating the sensation of two objects overlapping each other to some extent, which is called diplopia. The binocular vision has the advantages of making up the defect of blind areas in the monocular vision, expanding the vision field and generating stereoscopic vision. When viewing an object with both eyes, the sense of the thickness of the object to be viewed, the depth or distance of the space, and the like can be subjectively produced, which is called stereoscopic vision. The main reason for this is that the images of the same object to be viewed on the retinas of both eyes are not exactly the same, and the left eye sees more of the left side of the object from the left, while the right eye sees more of the right side of the object from the right. The image information from both eyes is processed by the advanced central vision system to generate a three-dimensional object image. However, in monocular vision, a certain degree of stereoscopic sensation is sometimes also produced, which is mainly obtained by accommodation and monocular movement. The stereoscopic vision of monocular visuals is significantly weaker than binocular vision. The two-picture scheme has a strong advantage in stereoscopic vision.

The myopia training and treating principle of the utility model is as follows:

according to human visual physiology, when people see a near, the eyes must be integrated in the visual axis direction, so that the adjustment is enhanced, and the pupil is narrowed; when looking far away, the visual axes of the eyes are scattered, the adjustment is relaxed, and the pupil returns to the original size or increases slightly, which is called the triple movement of looking near and looking far. The method is to apply the pre-designed 3D animation projected in the convex lens to make the visual focus of the observer move alternatively with the distance of the object in the animation, the ciliary muscle of the eyes of the observer continuously moves and relaxes, and the tension of the adjusting function of the eyes is relieved, so that the vision can be gradually improved or recovered to be normal.
