The Vision Source Experience

Advanced Pre-Test

During our Advanced Pre-Test, one of our vision care professionals will carry out a series of non-invasive tests to gather as much information as we can about your overall ocular health.

Latest Technology: For Better Vision Care

We use current technology, such as our Optomap® Retinal Scanner and OCT visual field analyzers (where available) to detect diseases and conditions that other exams might miss.

We'll also look for issues such as:

  • Colour blindness
  • Depth perception
  • Eye fluid pressure
  • Peripheral vision


optomap® Retinal Scans

Many Vision Source doctors use the Optomap Retinal Scanner (where available), a digital imaging device that scans 80% of your total retina (as opposed to 20% from traditional exams), which allows us to detect conditions such as glaucoma, diabetes and even cancer. 

The Optomap offers:

  • A 200-degree view of your retina
  • Quick, easy and painless scans
  • Scanning for adults and kids
  • Detection of a variety of diseases


OCT (Optical Coherence Tomography)

Vision Source is proud to offer our patients OCT testing (where available), a device that scans your eyes and presents the information as a high-resolution 3D image. This detailed view allows us to get a better understanding of how your eyes are functioning.

A SPECTRALIS exam is capable of seeing:

  • All 10 layers of your retina and optic nerve
  • Diseases such as glaucoma and diabetes
  • Objects 1/1000 the width of a strand of hair
  • Changes in your overall vision health

Ensure your eyes are seeing the world in the best way possible. Get an Advanced Pre-Test at a Vision Source near you.
