Binocular Vision Dysfunction

The ability to see is a remarkable function of the human body. But debilitating symptoms such as blurred vision, headaches, dizziness, anxiety, and balance problems can make it difficult for a person to live their life.

What most people do not realize is these symptoms could actually be a result of their eyes having trouble working together as a team to create one clear image, a condition called Binocular Vision Dysfunction (BVD).

Approximately 10 to 20 percent of the world’s population suffers from BVD. These patients have been everywhere, seen everyone, and despite their efforts, they are unable to find relief.

Through our work at Monocle Eye Care & Eyewear Gallery, we help to diagnose and treat BVD in patients and bring awareness to our region’s doctors, optometrists, ophthalmologists, physical and occupational therapists, and other health care providers who are essentially unaware of this condition.


What is BVD?

Binocular Vision Dysfunction describes any condition where the two eyes have difficulty working together as a team to create one clear image. This results in image misalignment. The body attempts to correct this vision misalignment by overusing and severely straining the eye muscles.

In people with normal binocular vision, their eyes work in tandem, perfectly in sync at all times, to send one clear, focused picture to the brain. However, in people with Binocular Vision Dysfunction, the eyes do not work together and are not perfectly synchronized – this makes it difficult for them to see one clear image.

When the misalignment is severe, it causes double imagery or double vision. However, in most cases, the misalignment is very subtle, historically making it difficult to identify. Even when the misalignment is small and physically unnoticeable, the symptoms can be debilitating.


The Patient Experience

While at least 10% to 20% of the population suffers from Binocular Vision Dysfunction, almost no one knows about this condition. To make matters more difficult, people suffering from BVD have a small amount of vision misalignment not found on a routine eye exam. With our micro-prism lenses, patients are immediately able to regain their quality of life.

Could it be my eyes? Take the quiz!

Dr. Flaherty is a specialist in the diagnosis and treatment of Binocular Vision Dysfunction and has trained under the Founder of NeuroVisual Medicine, Dr. Debby Feinberg of the NeuroVisual Medicine Institute in Michigan. Dr. Debby and her colleagues have treated more than 10,000 local, national, and international patients who have been diagnosed with this condition.


What Doctors Have To Say About BVD

The network of medical professionals who refer patients to us has helped contribute to an understanding of Binocular Vision Dysfunction. What our collective research has taught us, is that oftentimes patients have experienced doctors attempting to treat their symptoms rather than the actual cause – which could very likely be a patient’s eyes. This leads to patients being misdiagnosed and prescribed medications that do not help and therapies that do not bring relief.

When treated with our realigning micro-prism lenses, the average patient experiences an 80% reduction of symptoms by the end of treatment.
