Hello, myopia above 600 degrees is already high myopia. Only professional eye hospitals can have strict inspection and wearing procedures for orthokeratology lenses. If you are in Zibo, you can go to Kang Ming Eye Hospital in Zibo.

Orthokeratology can not only achieve normal vision standards during the day, but also help myopia patients control the growth of myopia by wearing and changing corneal curvature at night. However, it is recommended that you develop good eye habits in your daily life and work, pay attention to eye rest, avoid strenuous movements of your eyes and head, and prevent retinal detachment.

I hope these suggestions can be adopted by you ~ thank you ~
