We help patients recover from concussion, brain injury, and post-COVID vision problems with personalized Neuro-Vision Rehab programs that restore comfort and focus.

Neuro-Vision Rehab is a specialty area of optometry that retrains how the eyes and brain work together after trauma or illness. Patients often come to us with double vision, dizziness, headaches, light sensitivity, or difficulty reading following a concussion, whiplash, stroke, or long COVID. Unlike routine eye exams, Neuro-Vision Rehab addresses the functional problems that make everyday life, like walking in a store, using screens, or driving, exhausting or overwhelming.

Patients who benefit from Neuro-Vision Rehab often experience:
If you or a loved one has these symptoms, Neuro-Vision Rehab may provide the relief you’ve been searching for.
Dizziness can result from a poor integration of the visual and vestibular systems. Neuro-Vision Rehabilitation can help to recover it.
We use advanced assessments to identify how your visual system is functioning, then design a program that may include in-office therapy, home-based activities, and, in some cases, syntonic light therapy.
Dr. Yan Ling Liang brings fellowship-level training and has published research on post-COVID vision dysfunction, making her the first provider in Markham with a Neuro-Optometric Rehabilitation fellowship.
Families appreciate that she explains results clearly in English, Cantonese, or Mandarin, ensuring patients feel supported and understood.


Patients and providers sometimes use the term Neuro-Optometry when talking about vision care after brain injuries or neurological conditions. At Warden Optometry, we use the term Neuro-Vision Rehab because it better reflects our focus on recovery, function, and quality of life. In practice, the two terms often overlap: both describe care for patients with visual problems following concussion, traumatic brain injury, stroke, whiplash, or post-COVID inflammation.
Dr. Yan Ling Liang has fellowship-level training in this field and is completing her Level 3 requirements, including published research on post-COVID visual dysfunction. This expertise places Warden Optometry among the few clinics in the GTA offering specialty-level Neuro-Vision Rehab care. Whether you hear it called Neuro-Vision Rehab or Neuro-Optometry, our goal remains the same: to restore comfort, improve focus, and give patients the tools to return to school, work, and everyday activities with confidence.
