There are probably dozens of optometrists in the hospital, at least I used to. Actually, optometrists don't have to go to the hospital. Optical shops are also good. After all, they are exposed to these things. On the one hand, they may be more professional. As for Xuhui or Minhang, you should be able to do both, or go to a place far from the train station. This is a wholesale market for glasses. There are many optical shops. If you have concerns, you can go to Don.

I hope my answer can help you!
