ADHD or BVD? Understanding the Overlap and the Potential for Misdiagnosis

How Binocular Vision Dysfunction Could Be Mistaken for ADHD in Children and Adults

Attention Deficit Hyperactivity Disorder (ADHD) is one of the most commonly diagnosed neurodevelopmental disorders in children and adults. However, what if the symptoms attributed to ADHD were actually caused by an undiagnosed vision problem? Binocular Vision Dysfunction (BVD) is a condition in which the eyes struggle to work together as a team, leading to symptoms that closely resemble ADHD. Misdiagnosis can result in unnecessary treatments and prolonged struggles in school, work, and daily life.

At NeuroVisual Specialists of Florida, we specialize in diagnosing and treating BVD, helping patients overcome vision-related difficulties that may be mistaken for ADHD. This blog will explore the connection between ADHD and BVD, the key symptoms that overlap, and how proper diagnosis and treatment can significantly improve quality of life.

The Connection Between ADHD and Binocular Vision Dysfunction

Many individuals diagnosed with ADHD experience difficulties with focus, reading, and attention span. Interestingly, these same challenges are also seen in people with BVD. The connection lies in the way the brain processes visual information. When the eyes are misaligned, the brain struggles to merge the two images into a single, clear picture. This constant effort to correct visual input can lead to:

• Difficulty concentrating
• Frequent loss of place while reading
• Trouble with comprehension
• Restlessness and fidgeting
• Headaches and eye strain

Because these symptoms closely resemble those of ADHD, many individuals with BVD may be misdiagnosed or have an undetected vision issue contributing to their struggles.

Overlapping Symptoms: ADHD vs. BVD

Understanding the key similarities between ADHD and BVD can help parents, educators, and medical professionals recognize when vision testing should be considered.

Symptoms of ADHD

• Difficulty sustaining attention
• Impulsivity and distractibility
• Hyperactivity and excessive movement
• Problems following instructions
• Academic struggles

Symptoms of Binocular Vision Dysfunction

• Difficulty reading (skipping words or losing place)
• Trouble focusing on written text
• Eye strain and headaches
• Sensitivity to light
• Feeling overwhelmed in crowded spaces

Because BVD affects the way the brain processes visual stimuli, children and adults with this condition may appear inattentive, struggle with reading assignments, or avoid visually demanding tasks—all of which can be mistaken for ADHD.

Real-Life Scenarios: The Classroom Struggle

Imagine a young student, Alex, who has been struggling in school. His teacher notices he frequently looks away from his book, fidgets in his seat, and complains of headaches. His parents take him to a doctor, who diagnoses him with ADHD and prescribes medication. However, despite treatment, Alex continues to struggle with reading and concentration.

After an evaluation with a neurovisual specialist, it turns out that Alex has BVD. His eye misalignment was making reading difficult, causing him to lose focus and become restless. Once fitted with prism glasses—custom lenses designed to correct eye alignment—Alex’s reading improved, and his symptoms diminished significantly.

This scenario is not uncommon. Many children and adults endure years of frustration before discovering that vision therapy or corrective lenses are the true solution.

The Importance of Proper Diagnosis

Diagnosing BVD requires specialized testing that goes beyond a standard eye exam. At NeuroVisual Specialists of Florida, we conduct comprehensive neurovisual evaluations to identify even subtle misalignments that could be impacting focus and attention. Our approach includes:

• In-depth vision assessments
• Advanced eye-tracking technology
• Personalized treatment plans

If you or your child have been diagnosed with ADHD but still struggle with reading, focus, or headaches, a BVD evaluation may provide clarity and relief.

Transforming Lives with Prism Glasses

One of the most effective treatments for BVD is prism glasses. These specialized lenses help realign the eyes, reducing visual strain and improving focus. Many patients experience immediate relief from symptoms, leading to:

• Better reading comprehension
• Increased attention span
• Reduced headaches and eye fatigue
• Improved academic and work performance

Addressing BVD can be life-changing for individuals previously diagnosed with ADHD, offering an alternative or complementary solution that targets the root cause of their struggles.

If you or your child have been diagnosed with ADHD but continue to experience difficulties with focus, reading, or frequent headaches, it may be time to explore Binocular Vision Dysfunction as a potential underlying cause.

At NeuroVisual Specialists of Florida, we provide expert diagnosis and treatment for BVD, helping patients reclaim their ability to focus and succeed. Schedule a consultation today to determine whether BVD could be affecting you or your loved one’s daily life.
