Dr. Chang is absolutely incredible - thorough and very interested in her patients' continued vision health. I was amazed at how much time she was willing to spend explaining exactly what was going on with my eyes and why she was or was not concerned. Completely blew away my expectations - could not recommend more.

Dr. Sharon Yang is one of the best optometrists I personally ever met. My whole family had been doing eye exam with her for the past couple years. Dr. Yang recently took over this place at the begging of 2019, which she is the new owner of Cupertino Optometry. For me personally, I am Dr. Yang's Ortho-K patient and I recently decide to follow her to her new clinic that she opened by her own. Since every time when we have a follow-tp that she went through everything as detail as possible as well as reminding me to get the amount of sleep I need. Not simply for the best performance of Ortho-K, but also for my health as well as my mental health. Dr. Yang is a really professional optimist as she went through everything throughly in a professional manner, and try to explain to us in understandable way as well as answer all questions patiently. Dr. Yang is a doctor that actually cares about her patient, as she makes sure the product you are getting are essential for you, and she also do a follow-up call to make sure everything is good. Unlike some other places that all they do is trying to sell you the product even though you don't even need it. Couple weeks ago I had a minor hordeolum/ stye eye that I called her that I want to have a visit to her clinic, she told me that I can try to have hot pack on my eyes as well as having lighter diet. After couple days, she called me for the follow-up about my stye eye and I told her everything is all good now. I totally recommend her, she is a very friendly optimist and really cares all her patient. PS: She can speak both mandarin and english fluently and explain situation to patient professionally in both languages.

Went here to get CRT lenses and in the beginning it was okay. However, in the recent year or so, they have constantly flaked on me getting my new lenses even though I was supposed to get them last year. They said they'd "call me back about my lenses the morning after" but never did, and when I called they didn't pick up. My current CRT lenses are fogging up my vision and it's hard to see in class. Even with a solid 8 hours of sleep my vision is still blurry and I have to wear my glasses. They were supposed to have my lenses a long while ago but never got to it, which is not okay when my current lenses are not working and sometimes even causing pain and much inconvenience. Unreliable business and the price only exponentially increases every year. I didn't pay hundreds and hundreds for poor service and blurry vision. Update: I've gone off the CRT lenses and will be switching over to soft ones since CRT no longer works. Ridiculous that they didn't allow me to try both trial lenses while all my friends who've worn contacts were able to freely try multiple contact types before choosing. Forced me into getting multifocal contacts which are over $80 more per box than regular ones even tho I'm not farsighted and my vision is no longer changing. Outrageous that they were not accommodating at all and never even got my lenses and refund. Never got an email back about trying out the other lenses and the current ones have been giving me migraines, dryness, and blurry vision, not to mention being over 3 times as unnecessarily pricey. Just seem to be taking my money and not providing reliable service.
