Frequently Asked Questions


Do you take insurance?

Yes, we accept the following vision insurances:

  • VSP 
  • Costco employee insurance
How much does an eye exam cost?
A comprehensive eye health and vision exam is $85. A basic contact lens exam is $135. If you have astigmatism or need bifocal correction and want to wear contact lenses, there is a modest additional cost.
Will I receive a written prescription after the exam? Will the prescription be accepted anywhere?

We will supply a written prescription and summary of your exam as you leave the office.The prescription is valid anywhere in the U.S.

I had an eye exam a little over a year ago, and my vision seems fine. Why do I need another exam?

We think it is important that all of our patients receive an annual eye exam. Your vision can change over a 12-month period. A regular check-up enables us to uncover any sight-threatening ocular conditions that can develop, unnoticed by you.

Why does it cost more for a contact lens exam?

We do additional testing with contact lens patients to measure the curvature of the eye to ensure that we prescribe the lens that optimizes fit and comfort. We also do an evaluation after you have worn the lenses for a given period to make sure there are no complications.

Do you need to be a member of Costco to get your services?

No, you do not need to be a Costco member to have an eye exam with Dr. Nguyen. I am an independent doctor of optometry who chose to locate my practice at Costco, which is my landlord. I make no income from selling glasses or contacts, only from providing comprehensive exams and treating ocular disease.
