What is the therapeutic effect of eye protection pavilion? How is the treatment?

The treatment effect of eye protection hall is quite good. My child is being treated in the eye protection hall. Their purpose is to draw pictures and racket balls. I am quite relieved to treat my child's myopia by purely physical methods. My child used to have a left eye of 0.3 and a right eye of 0.4. After a course of treatment, his eyes have now recovered to 1.0. I'm still doing health care in the eye protection hall. I also introduced the children of several colleagues to do it, and the effect is not bad. Thank you very much for the eye protection hall.
