Trainer for improving regulatory function of eyes

Abstract

The invention discloses a trainer for improving the regulatory function of eyes, and belongs to the technical field of medical devices. The trainer comprises a box body, a sighting mark group, positive and negative lenses, a control switch, a microprocessor unit and a voice recognition module, wherein two rotating discs are arranged on the box body; lens holes for installing the positive and negative lenses are formed in the rotating discs; axle centers of the rotating discs are connected with a stepper motor through a coupling; the sighting mark group is arranged in a position which can be seen through the positive and negative lenses; the microprocessor unit, a power supply unit, a signal input unit, a signal output unit and a first wireless communication unit are arranged on the control module; a voice processing unit, a voice gathering unit, a power supply unit and a communication unit are arranged on the voice recognition module; and the control switch is electrically connected with the signal input unit of the control module. The trainer greatly facilitates the changing of the positive and negative lenses through the rotating discs, guarantees the cleanliness of the positive and negative lenses, and greatly facilitates the operation through the voice recognition module.

Description

technical field [0001] The invention belongs to the technical field of medical devices, in particular to a training device for improving binocular adjustment function. Background technique [0002] In today's society, more and more people are engaged in close-distance work such as computers and copywriting. At the same time, with the continuous acceleration of human office rhythm, the problem of visual fatigue is also coming. However, the problem of visual fatigue is often not paid attention to by everyone. Therefore, as The increasingly serious problem of visual fatigue has become one of the important indicators of human sub-health. At the same time, visual fatigue has also become an invisible killer of human learning and work efficiency. [0003] Therefore, visual training device arises at the historic moment, and existing visual training device is mainly divided into two classes: a class is a hand-held visual training device, and its main structure is: on a support frame ...

AI Technical Summary

Problems solved by technology

[0004] The other is a non-handheld visual trainer. For example, the Chinese patent application number CN201120316547.4 discloses a trainer for improving the binocular adjustment function. Functional trainers have the following defects: 1. It is cumbersome to replace the positive and negative lenses, and in the process of changing the positive and negative lenses, the positive and negative lenses are often polluted or scratched; thereby reducing the visual acuity. The effect and efficiency of training; 2. Since the speech recognition module is not used, the user needs to raise his head once every time he trains, and inform the visual trainer of the results he sees, and the visual trainer then analyzes and judges the training results, so The training process is cumbersome, labor-intensive, and the misjudgment rate is relatively high; 3. Since the traditional visual target group irradiates the visual target group with light, the light enters the trainer's eyes through the diffuse reflection of the visual target group. Therefore, The intensity of the light will play an extremely important limit on the training results, which often leads to poor training results; at the same time, stronger or weaker lights often have a certain degree of side effects on the trainer's vision; therefore, the design It is particularly important to provide a training device that is easy to replace positive and negative lenses, has a voice recognition function, and is comfortable to use and improves the adjustment function of the eyes.
