Does Guangzhou Sun Yat-sen University Eye Hospital have glasses? My left eye is 450, my right eye is 550, and I have to go there to get an ok mirror. I hung up the doctor's number on the internet. Should I return it? There are many ok glasses brands in Zhongshan Eye Center, with prices ranging from 5800 to 1 10,000. Just go to the hospital for a fitting, and it won't be so troublesome to register online. Before matching glasses, there will be relevant eye examinations to ensure that the eyes are suitable for wearing ok glasses. If the eye parameters are all right, it is good to match a cheap one. At present, there is little difference in the material design of ok mirror. Different prices are just different brand pricing. Just choose the one with good cost performance.
