Description

Training system for human eye convergence and dispersion flexibility Technical Field The invention relates to the technical field of ophthalmic medicine, in particular to a training system for the convergence and dispersion flexibility of human eyes. Background When the visual system of the human body meets the requirement of near vision, optical adaptation is mainly realized through precise regulation and control of neuromuscular. When a near target is watched, the body promotes the curvature of the crystalline lens to be increased through the contraction action of the ciliary muscle in the eye, so that the refractive power of an eye refractive system is enhanced, the object image is ensured to be accurately focused on the central fovea of the macula retinae, and the function of changing the refractive state for adapting to the near vision requirement is called as an adjusting function. In the process, a cooperative mechanism of binocular motion is generated, namely, collective reflection, namely, synchronous internal rotation motion is generated by the eyes, and the accurate alignment of the visual axis to the target object is realized by adjusting the included angle of the visual axis. Based on the physiological characteristics, clinical visual function training can be realized through a progressive scheme of monocular adjustment function strengthening, binocular aggregation/dispersion capability improving, binocular adjustment and aggregation cooperative integration, and systematic training establishes a perfect binocular cooperative mechanism, so that visual disorders such as blurred vision, compound vision and the like can be effectively improved. However, the existing visual function training method has the problems of complex operation, easy interference of training results and the like in the specific implementation process, and influences the accuracy and efficiency in clinical application. In particular, the prior art generally wears lenses having a certain degree of prism for the trainer, and the trainer continues training after the trainer is able to clearly see the optotype at that degree of prism, and then changes the lenses to other degrees of prism. Because the prism degree of each prism is determined, and the prism degree change gradient among the prisms is larger due to the economic consideration, the prism degree adjustment flexibility in the training process is poor, finer adjustment cannot be achieved, and the accuracy of the training process is reduced. Moreover, the traditional training mode can only record the whole aggregation training period of each round of training and the final result of human eye aggregation and dispersion capacity, and the subsequent training strategy is adjusted according to the whole period and the final result. The mode can not know the individualized detail condition of the trainer in the training process, the follow-up training strategy can not accurately attach to the actual condition of the trainer, and the training efficiency is reduced. Disclosure of Invention First, the technical problem to be solved In view of the above-mentioned shortcomings and disadvantages of the prior art, the invention provides a training system for human eye dispersion flexibility, which solves the technical problems that the prism degree adjustment flexibility in the training process is poor and fine adjustment cannot be achieved in the prior art. (II) technical scheme In order to achieve the above purpose, the main technical scheme adopted by the invention comprises the following steps: the embodiment of the invention provides a training system for human eye gathering and scattering flexibility, which is used for training human eye gathering and scattering rapid switching capacity, and comprises the following steps: The display device is used for displaying a training image, and the training image comprises two split-view patterns; The split vision lens device is arranged at a preset distance of the display device and is used for a trainer to watch training images displayed by the display device through the split vision lens device; The feedback device is used for receiving response information of a trainer after watching the training image; And the analysis device is respectively connected with the display device and the feedback device in a communication way and is used for generating a training image displayed by the display device and adjusting the offset distance of two split-view patterns in the newly generated training image according to the accuracy of the response information so as to adjust the equivalent prism degree of a trainer when watching the training image. Optionally, in the analyzing device, the adjusting the offset distance of the two split view patterns in the newly generated training image to adjust the equivalent prism degree of the trainer when watching the training image includes: adjusting the offset distance of two sub-view patterns in the traini
