In recent years, with the popularization of various smart electronic devices, young students are using more and more electronic products in the process of study, life and entertainment. The myopia rate of young people is also increasing year by year. Myopia is becoming younger and more severe. It has become a big issue concerning the country and the nation.

When looking at things at different distances and with different brightness, the human eye has a certain ability to automatically adjust to make the image on the retina as clear as possible under various circumstances. The essence of juvenile myopia is that the adjustment function of the eye muscles declines, causing the distant light to focus on the front of the retina after being refracted by the eye, and cannot form a clear image on the retina. It can be seen that to prevent myopia, it is necessary to avoid the excessive tension of the eye muscles, which leads to the decline of its adjustment function. At present, there is no corresponding solution to the contradiction between the use of electronic products and eye myopia, and the eyes need to rest. In the process of looking at electronic products such as mobile phones for a long time, the eye muscles are not relaxed and exercised, which will inevitably lead to myopia .

Therefore, further improvement is required.
