Transforming Patient Lives, and Optometry Practices

When our founder Dr. Debby Feinberg cared for her first Binocular Vision Dysfunction (BVD) patients in 1995, the scope of this condition was completely unknown. As momentum grew and success treating BVD patients with microprism lenses continued, patients began traveling from across the US and from abroad to seek her care.

We now know that about 20% of the population has Binocular Vision Dysfunction – and without proper care these people go through life experiencing severe symptoms without any answers.

With this as motivation, the NeuroVisual Medicine Institute was founded in 2013 with the mission to bring relief to BVD patients worldwide, by providing independent optometrists with the training and tools they need to become NeuroVisual Specialists in their region.

Our Training Program is a complete package that enables the independent optometrist to transform into a NeuroVisual Specialist:

– The latest clinical training
– Practice management tools
– Diagnostic equipment kit

We have now trained over 30 optometrists who have gone on to help 1,000s of patients nationally and internationally. Are you ready to join us in transforming lives?

Our Founders

Debby Feinberg


Dr. Debby Feinberg is the Director of Clinical Care at Vision Specialists of Michigan, and has been performing pioneering work with Binocular Vision Dysfunction (BVD), which is the cause of headaches, dizziness, gait imbalance, anxiety, light sensitivity, neck pain and reading difficulties. She and her colleagues have treated more than 15,000 patients with BVD with microprism lenses and noise cancelling devices, of which half have been TBI / ABI patients. Her research (presented nationally and internationally) demonstrates that in those TBI patients experiencing persistent post-concussive symptoms, treatment with microprism lenses and noise cancelling devices reduces these symptoms by 80%.

Mark Rosner


Dr. Mark Rosner, a retired Emergency Physician, is the Director of Education and Research at the NeuroVisual Medicine Institute. He has been actively involved in developing the speciality of NeuroVisual Medicine and in Binocular Vision Dysfunction (BVD) research since 2005. He is co-author of peer-reviewed articles on TBI and BVD and has presented lectures and posters on this topic nationally and internationally. He led the effort to validate the Binocular Vision Dysfunction Questionnaire, which is used to identify patients who most likely have BVD that will benefit from treatment.
