TECHNICAL FIELD
[0001] The utility model belongs to visual training device technical field relates to a folding stereoscope. BACKGROUND
[0002] When the eyes of a person are not consistent, the good eye and the poor eye are prone to competition, and the good eye will inhibit the poor eye, so that the retinal imaging of the poor eye is partially or completely filtered out. This physiological phenomenon is visual inhibition. When there is visual inhibition, disinhibition training and binocular fusion training are needed to establish good binocular single vision function.
[0003] A stereoscope is a special visual tool made by using binocular parallax principle. It can project two slightly skewed but identical pictures into the left eye and the right eye, respectively, so that the user can observe a stereoscopic image. When a stereoscope is used for training with professional pictures, it can improve vision, eliminate inhibition, and establish binocular simultaneous vision and stereoscopic vision. This is particularly beneficial to patients with deep inhibition, patients with amblyopia whose binocular visual acuity difference is within 2 lines, patients with insufficient convergence or divergence function, and patients with fusion function disorders. In related visual training, the stereoscope can help users establish binocular single vision function by allowing one eye to view the mirror image of the picture and the other eye to view the stereoscopic picture similar or identical to the mirror image, for disinhibition, fusion function, and stereoscopic vision training.
[0004] Traditional stereoscopes are generally designed as a rectangular frame structure with a single inclined mirror surface. For example, the patent with application number 2018218745455 discloses a reflecting stereoscope that can be folded but requires an additional support to support use, making the structure occupy a large space and not conducive to storage and portability, affecting use. The patent with application number 2022229185171 discloses a foldable reflecting stereoscope, which can be folded for storage, but both sets of visual target cards are placed on the inclined surface, making it impossible to perform drawing and disinhibition training.
