If you’ve been dealing with dizziness, headaches, anxiety in busy environments, or eye strain that no one can quite explain, the cause might not be neurological or even psychological. It might be your eyes. More specifically, how your eyes work together.
At Opto-Mization in Victoria and Nanaimo, we specialize in a condition called Binocular Vision Dysfunction (BVD), a commonly overlooked but life-changing visual issue that affects how your eyes and brain coordinate. And while BVD may not be a household term, it affects thousands of people across Vancouver Island who have never received an accurate diagnosis.
This article will help you understand what BVD is, how it shows up in everyday life, and how our clinic can help you finally get to the bottom of symptoms that may have gone unexplained for years.
What Is Binocular Vision Dysfunction?
Binocular Vision Dysfunction (BVD) occurs when the two eyes struggle to work together as a team. Even if you’ve been told your eyesight is “perfect,” BVD may still be affecting how your brain processes visual input.
When your eyes don’t align properly, your brain has to work harder to create a single, stable image. This extra effort can cause a wide range of symptoms, many of which are mistaken for other conditions like anxiety disorders, migraines, vestibular dysfunction, or even motion sickness.
Unlike typical vision problems, BVD is a functional issue, not just a clarity issue. This means the eyes may see clearly, but the underlying coordination and alignment between them is off, creating confusion in the brain and distress in the body.
Why It Often Goes Undetected
Traditional eye exams assess visual clarity and may include basic checks on how the eyes work together— but they don’t specifically test for Binocular Vision Dysfunction (BVD).
At Opto-Mization, our team performs advanced functional testing that looks beyond 20/20 vision. We evaluate:
- Eye teaming (how well your eyes align and coordinate)
- Eye tracking (your ability to follow moving objects smoothly)
- Depth perception and convergence (how your eyes work at near and far distances)
- Visual processing and how your brain handles the input
This functional approach allows us to detect subtle issues that standard exams and online tests can easily miss.

The Symptoms of BVD: More Than Just “Eye Strain”
One of the biggest challenges with BVD is that its symptoms often appear unrelated to the eyes. Patients in both our Victoria and Nanaimo clinics frequently tell us they’ve been to multiple specialists—neurologists, ENTs, mental health professionals—without a clear answer.
Symptoms of Binocular Vision Dysfunction can vary from person to person. Some individuals experience just one, while others may notice several. Below are some of the most commonly reported signs:
- Dizziness or disorientation, especially in busy or bright environments
- Headaches, particularly around the eyes or forehead
- Nausea or motion sickness while driving or riding in a car
- Anxiety or a feeling of panic in grocery stores, malls, or crowds
- Light sensitivity
- Difficulty reading or focusing on text
- Feeling “off” or disconnected from surroundings
- Fatigue after short periods of concentration
- Poor balance or frequent stumbling
It’s easy to see why BVD is so often misdiagnosed. Many of these symptoms overlap with concussion after-effects, vestibular disorders, ADHD, or generalized anxiety.
In fact, many patients we see have been told, “Your eyes are fine” or “It’s just stress”—only to later discover that a treatable visual misalignment was behind their symptoms all along.
BVD and Mental Health: The Missing Link?
For many people, symptoms of BVD create a constant sense of tension, unease, or visual overwhelm. This can feel a lot like anxiety or panic, especially in visually demanding spaces like grocery stores, shopping malls, or while driving.
It’s not uncommon for patients to be referred to psychologists or prescribed medication, only to find little relief. That’s because the root issue may not be emotional at all—it may be sensory overload from poorly coordinated visual input.
When your eyes can’t team properly, your brain is forced to process double images, blurred information, or rapid shifts in visual focus. This overload can trigger physical stress responses that mimic anxiety or dizziness, even when nothing else is medically wrong.
By addressing the underlying visual dysfunction, many of our patients report a dramatic reduction in both physical and emotional symptoms.
Local Stories from Victoria and Nanaimo Patients
At our Victoria and Nanaimo clinics, we often meet patients who’ve spent years looking for answers. Some are children who struggle with reading and focus. Others are adults who feel dizzy every time they walk into a supermarket. Some are recovering from concussions and can’t explain why they still feel “off,” months later.
What they all have in common is this: their symptoms didn’t match their test results, and they felt unheard—until now.
Our comprehensive exams give patients a new path forward. Once BVD is diagnosed, many can begin seeing relief within weeks through the use of specialized lenses and targeted therapy.
How We Treat BVD at Opto-Mization
Once we’ve identified that you have Binocular Vision Dysfunction, we build a customized treatment plan that may include:
1. Therapeutic Glasses with Prism Lenses
These lenses gently shift how light enters your eyes, realigning the images your brain receives so it doesn’t have to work overtime. Patients often experience immediate relief of symptoms like dizziness, headaches, and disorientation when wearing prism lenses.
2. Vision Therapy
In some cases, we may recommend a series of in-office or at-home exercises to strengthen eye coordination, tracking, and convergence. Vision therapy is especially effective for children or adults with long-standing visual imbalances.
3. Ongoing Monitoring and Adjustments
As your BVD treatment progresses, we encourage you to monitor your symptoms and reach out if you notice any issues. Treatment plans can be adjusted as your visual system adapts.
Everything we do is based on objective findings, not just symptom checklists. That’s how we ensure effective, evidence-based outcomes.
