Frequently Asked Questions

Here are the answers to your frequently asked questions. Any further questions can be sent to our email, frontdesk@doctoryeung.com, or give us a call at 236-427-8797.

What kind of tests are provided at WestCoastOD?

All tests necessary for a comprehensive health eye exam.  Additional tests are retinal imaging, OCT= Optical Coherence Tomography, pachymetry (thickness of cornea measurement), Visual Fields.  We currently fit speciality Rigid Gas Permeable/Scleral Lenses for patients with Keratoconus.  In the future we will also be doing myopia management.

How Often Should You Get An Eye Exam?

Once per year is the recommended time, but it is fine to wait for coverage (often every 2 years) if there is no noticeable change. If there is a large change or vision health issue, we can still see the pt as the doctor can bill a minor visit or there may be some billable health check.

Do you have doctors that speak other languages?

Yes we do. We have doctors that speak: English, Mandarin, Spanish, Cantonese, Korean, French, Vietnamese and Punjabi. When booking, give us a call and specify if you would prefer a doctor that speaks a different language than English.

How do I read my prescription? 

OD is right eye, OS is left eye,

Sphere is the prescription distance, +; can see far away   -; can see close up,

Cyl is the astigmatism (uneven cornea),

Axis is the degree or angle of astigmatism,

Add is for multifocal/ reading glasses,

PD is pupil distance 

Do you sell glasses? Does the prescription also work for contact lenses?

Costco handles glasses and contact lenses. We are INDEPENDANT from Costco, thus we do not own the products (glasses or soft contact lenses). The Rx provided to you by our doctors is a spectacle Rx only, because for contact lenses we do not fit those since we do not directly sell the product (we are also Independent from Costco Optical).  

 

Free fittings are provided at Costco Optical Departments. Alternatively, our spectacle Rx can be given to any other opticians in BC who will properly fit the soft contact lenses that they are selling (unless you are needing specialty RGP/hard or Scleral lenses from us; in which, we can order and DO FIT SPECIALTY contact lenses).

Optical can also fit lenses using your old frames.

Do you need a Costco Membership to book an appointment?

You do NOT need to be a Costco Membership to book an appointment with us. When entering Costco mention to the security that you are going in for an eye exam and they will let you through.

Do you do some different tests for diabetic patients?

We do extra tests such as OCT for diabetic patients, and we also dilate patients who are diabetic.  We also perform Visual Field tests for diabetic patients.  We like to monitor diabetic patients every 6 months.
