Understanding Binocular Vision Dysfunction (BVD)
Binocular vision dysfunction (BVD) is a condition in which the eyes struggle to work together as a team. This can lead to problems combining visual information from each eye to form a cohesive image. Unlike more commonly known vision issues such as nearsightedness or farsightedness, BVD often goes undiagnosed. Its symptoms are very similar to other conditions like migraines, anxiety, or balance disorders.
BVD stems from issues in the small muscles of the eyes, which are responsible for aligning the eyes. These muscles ensure that the images each eye sees can fuse into one clear picture. When these muscles don't work correctly, the brain receives two slightly different images, which it struggles to combine. This results in various visual and non-visual symptoms, affecting overall quality of life.
Many people with BVD are unaware that their vision problems are due to this dysfunction. Traditional eye exams may not detect it, as they typically focus on visual acuity rather than the coordination of eye muscles. This is why specialized testing and a comprehensive binocular vision evaluation are essential for an accurate diagnosis.
BVD can affect anyone, regardless of age, and its impact varies from person to person. Some might experience mild discomfort, while others suffer from severe symptoms. These symptoms can interfere with daily activities such as reading, driving, or using a computer.
Understanding this increasingly common condition is the first step towards effective management and improved quality of life.
Binocular vision dysfunction (BVD) is a complex condition that can arise from various causes. It is primarily related to the muscles that control eye movement and the coordination of the eyes. Understanding the underlying causes is crucial for effective diagnosis and treatment.

Diagnosing binocular vision dysfunction requires a comprehensive eye exam beyond standard vision tests. A detailed evaluation of eye alignment and coordination is essential. During this assessment, our eye care team uses a variety of tests to measure how well your eyes work together.

Binocular vision dysfunction (BVD) can significantly impact depth perception. Since BVD involves misalignment of the eyes, it can interfere with the brain's ability to accurately merge the images. This prevents creating a single, cohesive picture from both eyes.

Symptoms Of Binocular Vision Dysfunction
The symptoms of BVD can often be mistaken for other medical issues. You may experience headaches, especially after spending long hours on visual tasks such as reading, working on a computer, or driving. These headaches can be quite severe, and doctors often misdiagnose them as migraines.
Eye strain and fatigue are also common. These symptoms make activities that require sustained visual focus, such as reading, driving, or writing, challenging.
Another prevalent symptom is double vision, where a person sees two images of a single object. This may happen constantly or only on occasion, depending on how bad the misalignment is. Blurred vision is also common, causing objects to appear out of focus.
Many individuals with BVD report difficulty concentrating and maintaining attention. This can significantly impact work or academic performance and can sometimes be mistaken for ADD/ADHD.
Patients frequently report dizziness and balance problems as well. The brain relies heavily on visual input to maintain balance. When the eyes are misaligned, disrupted input leads to feelings of unsteadiness or vertigo. Some people might even experience motion sickness or nausea, especially when reading in a moving vehicle or playing video games.
Children with BVD often struggle with reading and learning. They may skip lines or lose their place while reading, and their performance in school might suffer. People sometimes mistake these symptoms for learning disabilities or attention deficit disorders. Behavioral changes, such as irritability or avoiding activities that require close vision work, are also common.
In addition to these visual symptoms, you may experience a range of physical discomforts. Neck and shoulder pain often occur due to the constant strain of maintaining proper alignment. Sensitivity to light, commonly known as photophobia, can make it difficult to be in brightly lit environments. This sensitivity, combined with other symptoms, can make daily activities challenging and reduce overall quality of life.
