What is Binocular Vision Dysfunction?

Our doctors at Vision Specialists of Michigan have made pioneering discoveries into the diagnosis and treatment of Binocular Vision Dysfunction, a group of conditions that cause There are six different muscles controlled by three different cranial nerves that coordinate the movement of each eye.

In order to achieve perfect binocular vision and to avoid double vision, the brain and all twelve muscles must work together so that each eye points directly at the object being viewed.

When the eyes cannot perform this eye teaming task accurately, this is referred to as binocular vision dysfunction.

The number of symptoms, and severity, are different for each person. Some people are disabled, while others aren’t bothered much.

Many people with Traumatic Brain Injury (TBI) develop a small amount of eye misalignment from their injury that cause these symptoms.

NeuroVisual Evaluation and Vis-Align™ Glasses: Correct the Aim, Fix the Strain and Reduce the Pain

In 1995 our doctors developed the NeuroVisual Evaluation (a specialized eye examination that finds the hidden misalignment) and Vis-Align™ Glasses (glasses that realign images by bending light beams). These groundbreaking glasses eliminate the need for the body to make any corrections to the eye alignment, While the body is doing the best it can to fix the eye misalignment, this approach causes a lot of problems. There has to be a better way to get the image onto the fovia without needing to reposition the eye. And there is!

Since 1995, our doctors at have performed groundbreaking research into the use of prism (in green) which is at the heart of our Vis-Align™ Glasses. Prism can bend beams of light, and can redirect the image (red dotted arrow) onto the center of the back of the eye (the fovea (big red arrowhead)) while the eye is in it's original, slightly misaligned position (black arrow). Since there is no need to realign the eye, there is no overuse of the eye muscles, which markedly reduces or eliminates the symptoms of Binocular Vision Dysfunction.

If The Walls of My Exam Room Could Talk

STORIES OF TRIUMPH over a common but often unrecognized visual ailment: Binocular Vision Dysfunction

By Debby Feinberg O.D. with Mark Rosner M.D. & Sherry Brantley

Who would have thought that a basic eye alignment problem could cause a person to be miserable or disabled? Yet that is exactly what is happening with Binocular Vision Dysfunction (BVD), a visual condition where there is a slight image misalignment which causes headaches, dizziness, anxiety, neck pain and reading difficulties. Using techniques developed by Dr. Debby Feinberg and her colleagues, patients are fit with prism eyeglass lenses that realign the images, resulting (on average) in an 80% reduction of symptoms.

This book contains the stories of those suffering from BVD, their difficult journey through life and the medical system, and their recovery and return to health using just a simple pair of properly prescribed prism lenses.
