Binocular Visual Dysfunction

Binocular Visual Dysfunction (BVD) is a condition in which the eyes struggle to work together as a coordinated team. Even when each eye may see clearly on its own, a slight misalignment between them can cause the brain to receive conflicting visual signals. This can lead to a wide range of symptoms, including headaches, eye strain, dizziness, blurred or double vision, and difficulty with reading or focusing. Because these symptoms often overlap with other conditions—such as migraines, vertigo, or anxiety—BVD is frequently overlooked or misdiagnosed.

Individuals with BVD may also experience issues with depth perception, motion sensitivity, and discomfort in busy visual environments like grocery stores or while driving. In some cases, the condition can affect posture and balance, as the body subconsciously adjusts to compensate for the visual misalignment. Diagnosis typically involves specialized testing beyond a standard eye exam, and treatment often includes customized prism lenses that help realign the visual system. With proper care, many patients experience significant relief and improved quality of life.
