Why do Guyuan teenagers need medical optometry glasses for myopia?

Lv Yingzhe, vice president of Guyuan Aier and director of optometry and pediatric ophthalmology, stressed that there is a optometry diagnosis and treatment process for formal and scientific glasses, because glasses are instruments for correcting vision in regular hospitals, not goods on the shelves. Regular medical optometry in the hospital can not only make young myopia patients get clear vision correction, but also make themselves feel comfortable. These all have strict optometry diagnosis and treatment steps. Computer optometry developed in 1970s belongs to objective optometry. This optometry machine is a combination of light, electricity and machine, and its principle is basically the same as that of optometry. In addition, infrared light source and automatic atomization device are used to relax eyeball accommodation. Because of its simple operation and high speed, it is widely popularized. However, all kinds of computer optometry instruments have certain errors. Although infrared light source and automatic fog viewer are used to relax the adjustment, the adjustment influence cannot be cancelled, especially for teenagers. It is often unscientific to simply use computer optometry. The error of computer optometry results is mainly due to high myopia, so computer optometry in regular hospitals is for reference only and cannot be fitted with glasses. After medical optometry in a regular hospital, it was confirmed that it was true myopia, and the five meters in front of my eyes were blurred, so I had to wear glasses to correct it. In addition to rest and washing time, you must wear matching glasses Wearing glasses is not only to control the growth of myopia, but also to study and work at a proper distance, so that the eye adjustment can have a normal coordination relationship and avoid eye fatigue.
