Binocular Vision Dysfunction (BVD) is the condition where the two eyes are misaligned, leading to the eyes producing two images rather than one perfectly merged image. This condition is under-diagnosed, not well understood by most medical professionals, and not tested for in any routine eye exams. It leads to a wide variety of mysterious and debilitating symptoms. However, it is EXTREMELY treatable with several modalities of treatment available, including Vision Therapy and Prism Lenses.
