Background

For binocular vision abnormality diseases such as hyperopia amblyopia, myopia amblyopia, ametropia amblyopia, amblyopia caused by abnormal retina and the like of children, the binocular vision abnormality diseases are generally detected by using a homography machine at present. The principle of the synoptophore examination is that the visual fields of two eyes are separated by utilizing two lens cones, a left picture is seen by a left eye, a right picture is seen by a right eye, an object image is projected to a certain position of retinas of the two eyes through a convex lens, and then the object image is transmitted to a visual cortex through a visual center to be processed, analyzed and synthesized. Therefore, the picture of the synoptophore is a core component of the synoptophore.

The traditional picture of the synoptophore is mainly made of a glass sheet which is used for drawing a pattern for detection on the surface of the glass sheet, but the picture is fragile, can bring potential safety hazards, is exposed outside and easily worn, and is easily stained and corroded by dust, dirt and the like in the surrounding environment, so that the service life is short, and the cost is high. Therefore, various improvements of the picture of the same-vision machine have been developed. For example, some manufacturers have proposed a picture film for a synoptophore, which includes a housing 1 and a picture core 2. The casing has installation space, and relative both sides have respectively on the casing and are suitable for observing the window in installation space, and the drawing core sets up in installation space, and the surface of drawing core is used for drawing required pattern, and the pattern just sets up to the window on the casing, and the drawing core adopts transparent material to make to in order to follow the pattern on the both sides window observation drawing core. Although the picture of the synoptophore can better overcome the defects of the traditional picture of the synoptophore, the new defects are caused. For example, the picture of the synoptophore has high precision requirements for the dimensions of the picture element 2 and the installation space 3, so that the manufacturing and assembly costs are high. Specifically, if the size of the core at the time of cutting and the length and width of the mounting space and/or the thickness of the core and the height of the mounting space are slightly different, the core may move in the mounting space not only in the X direction or the Y direction (see fig. 1 a), but also may tilt in the mounting space (see fig. 1 b), causing the detection pattern 4 to deviate from a predetermined position (for example, the position such as the center of the picture) and causing a deviation in the detection result.
