Mark Rosner, MD (or “Dr. Mark”) is a physician and clinical researcher whose work has been central to bringing Binocular Vision Dysfunction (BVD) into broader medical awareness. For more than two decades, he has studied why so many people experience headaches, dizziness, anxiety, and visual discomfort that traditional testing can’t explain—showing that even tiny visual misalignments can cause major symptoms.
He continues to lead research, lecture nationally, and collaborate with neurologists, emergency physicians, physical therapists, and optometrists to advance BVD as a recognized and treatable condition.
