Dr Yang is very warm and efficient. The staff is very courteous. This is my second visit.

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. Yang took over this place at beginning of 2019, she became the new owner of this business! I visited this place March 2019, and had very wonderful experience for eye examining and new glasses purchasing. They support vision insurance like VSP. Thank you Dr. Yang.

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 theyd call me back about my lenses the morning after but never did, and when I called they didnt pick up. My current CRT lenses are fogging up my vision and its 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 didnt pay hundreds and hundreds for poor service and blurry vision.Update: Ive gone off the CRT lenses and will be switching over to soft ones since CRT no longer works. Ridiculous that they didnt allow me to try both trial lenses while all my friends whove 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 Im 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.

I was out of town and needed contact lenses. Dr. Chang’s office was so accommodating with me. Had a great eye exam and the service was top notch.

Visited to get a prescription for contacts. Everyone there is very friendly and charming! Professional and clean, cant ask for 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. Yangs 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 dont 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.

A very professional office with exceptional service. I was very impressed with the eye exam and care I received from Dr. Chang.

I was there 1 year ago for check up, the doctor is nice and very thorough.I had a red eye one day a few months ago, and went to see the doctor just to make sure there is no serious problem, even I felt OK. I was scheduled in to see the doctor right away. However, when I arrived, they told me they need to charge me $50 for emergency visit. In my opinion, it is totally rediculous. NO ONE, NO ONE doctor charge you for same-day appointment. If it is emergency, I would have gone to emergency room or hospital already. It was useless for me to argue on-site because the owner set the policy. Later I did got $18 back because my insurance was able to pay them that amount.However, I decide this place is not a decent optometry, and will never go back again!!!BE ALERT!
