Embodiment Construction

[0013] As shown in Fig. 1, 2, binocular vision anisotropy detector comprises polarization glasses 13 and a jacket 1 that is provided with the interlayer that both ends are open and the visual target plate 2 that is slidably arranged in the jacket 1 interlayer, jacket 1 The jacket 1 and the sight board 2 are rectangular, the jacket 1 and the sight board 2 can be made of cardboard, the two short sides of the jacket 1 are open, the front of the jacket 1 is provided with an observation window 3, and the back of the jacket 1 is provided with a scale The window 4, the scale window 4 and the observation window 3 are rectangular. The observation window 3 is symmetrically arranged with a pair of polarizers 5 whose polarization directions differ by 90°. Be provided with fixed visual mark 6, in the present embodiment, fixed visual mark 6 is arranged on the left polarizer 5 behind, and fixed visual mark 6 is the short line segment that is placed in the long side direction along the visual ...

Abstract

An instrument for detecting the unequal visual image generated by two eyes is composed of a pair of polarized glasses, a dual-layer hollow plate with two open ends and the observing window, scaling rule window and fixed visual standard arranged respectively on its both surfaces, and a visual standard plate able to slide in said dual-layer hollow plate. Its application is also disclosed.

Description

technical field [0001] The invention relates to a binocular vision anisometry detector, which is mainly used for detecting binocular anisotropy caused by anisometropia, especially anisotropy caused by refractive surgery. Background technique [0002] At present, the methods used to detect anisotropy include: ① distance anisotropic visual mark on the comprehensive refractometer; ② red and green semicircle graphics; ③ computer video screen. Using the distance anisotropic optotype on the comprehensive refractor to check the patient can only get qualitative results, but not quantitative; the red and green semicircle graphic mode is the red and green semicircle optotype, and only the red semicircle can be seen at a glance , the other eye can only see the green semicircular optotype, but the red and green itself may cause anisotropy, and the degree of anisoform can only be measured in grades, and the visual angle of the target is relatively large, so it is difficult to measure sta...
