Most optical shops are free, and only a few have two kinds of optometry: free optometry and free optometry. It depends on your needs. If you want to have a thorough eye examination, you must pay the fee. It doesn't matter if you don't do anything else.

For example, optometry with LOGO glasses is free, but based on glasses, optometry is free. (No glasses, no optometry)

I remember the doctor's glasses and optometry seemed to charge 50 yuan.

Asian glasses, optometry charges around 50 yuan

Bao Dao glasses, optometry costs about 80,,, and so on. You can call for details first.
