Design and development of myopia prevention and control device integrating spectral stimulation and perceptual training

摘要:

随着电子产品的普及,青少年儿童使用电子设备频率的不断增长,导致青少年儿童近视率的上升；为控制近视率的上升,对近视早期的控制能够预防后期近视的发生,设计开发了一种基于融合光谱刺激和知觉训练的便携式近视预防装置；装置以基于全志A133主板的安卓系统控制,采用ESP32无线传输模块在用户手机应用端登陆后传输用户信息至服务器和装置屏幕显示,并作为主板和灯光模块的通讯模块；灯光模块包括一个具有恒流电源驱动的灯光系统,该系统包含红光训练、LED白光后像训练、RBG多光谱训练和LED引导眼肌调节训练等灯光训练功能,其中以红光训练为主要功能,通过大小合适、光强安全、光斑均匀的低强度激光稳定照射视网膜来防止并改善眼轴长度的增加,能够保证视网膜多巴胺的含量,加快脉络膜、巩膜的血液循环,从而抑制近视的发生和发展；在进行光照训练后,运用装置内置的Unity视觉训练软件,进一步辅助眼睛的近视弱视预防；该设计为便携式近视预防装置提供了一个新的视角,可应用于医疗保健设备。

Abstract:

With the popularization of electronic products, the frequency of use of electronic devices by teenagers and children continues to increase, resulting in an increase in the rate of myopia in adolescents and children. In order to control the increase of myopia rate, the early control of myopia can prevent the occurrence of late myopia, a portable myopia prevention device based on integrating spectral stimulation and perceptual training was designed and developed. The device is controlled by the Android system based on the Allwinner A133 motherboard, and uses the ESP32 wireless transmission module to transmit user information to the server and the device screen display after logging in on the user"s mobile phone application, and serve as the communication module between the motherboard and the lighting module. The lighting module includes a lighting system driven by a constant current power supply, which includes red light training, LED white light afterimage training, RBG multi-spectral training and LED guided eye muscle adjustment training and other lighting training functions, among which red light training is the main function. It can prevent and improve the increase in the length of the eye axis by irradiating the retina steadily with a low-intensity laser with suitable size, safe light intensity and uniform spot, which can ensure the content of retinal dopamine and accelerate the blood circulation of the choroid and sclera, thereby inhibiting the occurrence and development of myopia. After lighting training, use the built-in Unity vision training software to further assist in the prevention of myopia and amblyopia. The design provides a new perspective for portable myopia prevention devices that can be applied in healthcare equipment.
