What is a Contact Lens Exam & Fitting?
A contact lens exam is necessary to determine your contact lens prescription — which is different from your glasses prescription — and to ensure that your lenses comfortably fit on your eyes. We’ll also explore your eye health and discuss your lifestyle to see what lenses make the most sense for you.
We use advanced measurement tools like corneal topography, optical coherence tomography, and digital refraction to take detailed measurements of your eyes and determine if you have any front of eye conditions, like dry eye or keratoconus, that we need to account for. A subsequent fitting pairs you with the most comfortable contacts, which you then take home for a trial period. We’ll follow up with you to make sure your lenses are providing clear, comfortable sight!

Collaborative Patient Experience

Since so much of good contact lens health depends on excellent hygiene, our team will teach you how to ensure that your eyes and eyelids are in tip-top shape. And no matter how well we already know you, our doctors will take the time to learn your lifestyle and make personalized recommendations.

Our doctors love working with children of all ages and can help kids learn to use contacts for the first time! Additionally, we offer myopia management lenses for children, to hinder the progression of their nearsightedness now for clearer vision and healthier eyes in the future. We work with your little one to create a comprehensive plan to protect their sight and get them familiar with contacts early on. We’ll show them that contacts are a convenient, easy option — with a little upkeep!


For patients with hard-to-fit eyes or unique vision needs, don’t worry: there are contact lenses here for you! If you have severe astigmatism, you will likely require a toric lens; meanwhile, our dry eye patients and those with sensitive corneas find relief with scleral lenses. Specialty contact lenses means more options to find your best fit. Even if you’ve struggled with contact lenses in the past, we likely have a style that is comfortable for you!
Ordered a new pair of glasses and couldn’t be happier with them. Finally a prescription that I can read with. Needless to say, I’m very happy!
This was my second time there. I will be going back.
Thanks for the gift of better vision
Every person I encountered was professional and a wealth of information. There were so many options that I left there feeling that they care and they want to find the best one for me. I was very impressed and went home telling my husband about it.
1. The ease of online appointment scheduling and patient forms
2. Friendly staff at the reception area
3. Technician administering visual tests extremely knowledgeable and friendly.
4. Dr. Michael Lum clearly explained my results and my options so that I would receive the right prescription for my multiple visual needs
5. Huge selection of frames to choose from which could have been overwhelming but Erin hand selected many for me to choose from and between us we were able to quickly find the perfect pair.
I have never been excited to go to for an eye exam or to pick out glasses but I now look forward to my appointments at this office.
Dr Yamamoto is great. He takes the time to answer questions and doesn’t make you feel rushed.
Amelia helped me find the perfect pair of glasses and was really patient with me.
I’d recommend this office in a heartbeat!
I am a kind of person oriented to details and I have hard time to make up my mind especially when the store have a large selection of frames. They also search on internet the frame i wear now, they found it, ordered it will not pay for in until I am satisfied.
They are absolutely wonderful!
I strongly recommend this office of Mission Viejo Optometric Center.

So glad that I found my optometry center.
The most highly recommended vision center. If there was more then 5 stars I would have definitely gave it to the team.
That’s the place you should go to if you want to walk out with a smile on your face. They magically know how to draw a fat one on your face.
Dr Justine Hsieh is the best!
Very knowledgeable and informative. Been coming to this office for years, and I'm always impressed by the professionalism and friendliness I experience.
Hseih is very thorough and personable. In fact, their whole staff is excellent.
The office also has a wide selection of glasses to choose from. The whole team (including the doctor!) were happy to help give their input so I could select the frame that best fit me.
Would recommend this optometry office to anyone wanting to get an stress free eye exam with a great office attitude and friendly faces!
I booked my annual eye exam, and was going in feeling comfortable. On our call, Jody had asked me to make sure to bring my mask and to fill out some paperwork via email prior to my appointment, to reduce contact and time spent in the office. Upon arrival, I was asked to call the front desk to assure that I would be socially-distanced and everything was cleaned before entering. Once entered, Jody took my temperature and then walked me through some eye tests. She made sure to wipe all of the equipment down before use, which was very assuring. I then walked into my exam, and there was a sign on the chair before sitting down stating that it had been cleaned. I had an eye exam with Dr. Hsieh, and was extremely happy with her professionalism and knowledge. We ended up trying out some new contacts! James checked the schedule and had me book a 1-week follow-up appointment to make sure that they were to my satisfaction before ordering them.
I came back a week later with no problems, and ended up purchasing a year supply of contacts (which were shipped to my house promptly - in less than a week).
Overall, they are one business that is following COVID guidelines well, and I will continue to give them my service!
Dr. Chi's office uses state of the art equipment to aid in the examination process and this ensures that you do not need to have your eye dilated.
Dr. Chi's staff is friendly, caring and knowledgable. Maria, Jakub, Samantha and Lina put us at ease and walk us through the selection of frames, explain lens options and costs and also what our insurance will cover. We are very happy with Dr. Chi and his excellent staff.
I would definitely recommend this optometrist
Staff is also very friendly & helpful.
In addition, we have experienced the staff to be very professional, patient and kind when calling to change or make appointments. Also when checking in to be seen.
The office is very clean
I was greeted by Jacob who was warm and welcoming. I explained my vision problem and he asked if I wanted to be seen today. I said “yes”. Jacob checked my insurance and explained me the tests that would be performed. He was so kind and helpful. I was seen 30 minutes later and had a full eye exam and was fitted for contacts. I was so thrilled. I was seen by Dr Chi. Excellent Optometrist. He was very patience with me and explained and answered every question I had. He even assisted me by plucking sn ingrown hair from my eyelid. Wow! I checked out with the girls who were delightful . I had the best experience. The entire office staff was friendly and very helpful. Stop by and see them! You”ll be happy you did.
a new frame. They treats me like a family instead of another patient. Not having to dilate this year because of the tech they have might be one of the best part.
