Binocular Vision Dysfunction (BVD)

Binocular Vision Dysfunction (BVD) occurs when the eyes don’t work together properly, often causing headaches, dizziness, eye strain, and difficulty focusing.

Understanding Binocular Vision Dysfunction

Binocular Vision Dysfunction (BVD) occurs when the eyes are slightly misaligned and send two different images to the brain. Even small misalignments can place constant strain on the visual system, leading to physical and neurological symptoms. Because the misalignment is often subtle, BVD is frequently missed during routine eye exams.

Common Symptoms of BVD

• Headaches or migraines
• Dizziness, vertigo, or balance issues
• Eye strain or visual fatigue
• Difficulty reading or concentrating
• Anxiety in visually demanding environments
• Motion sensitivity or nausea
• Trouble driving, especially at night

What Causes BVD?

BVD may be caused by subtle developmental differences, facial asymmetry, concussions, or head injuries. In some cases, neurological or systemic conditions may also trigger binocular vision issues. Many patients are unaware that their symptoms may be vision-related.

Why BVD Is Often Misdiagnosed

Because BVD symptoms overlap with conditions such as migraines, anxiety disorders, vertigo, ADHD, or sinus issues, many patients receive treatment without addressing the underlying visual cause. Proper evaluation of how the eyes work together is essential for accurate diagnosis.

The NeuroVisual® Exam

The NeuroVisual® Exam goes beyond standard eye tests to evaluate eye alignment, coordination, focusing ability, posture, and balance. Even patients with 20/20 vision may have BVD that impacts daily comfort and performance.

Prism Glasses for BVD

If BVD is diagnosed, treatment may include customized prism lenses. Prism glasses help align the images sent to the brain, reducing visual strain and improving comfort. These lenses are custom-fit and may be adjusted over time.

Could BVD Be the Cause of Your Symptoms?

A short questionnaire can help determine whether your symptoms may be related to Binocular Vision Dysfunction.
