Traumatic Brain Injury (TBI) is a complex and potentially life-altering injury that can lead to a variety of long-term physical, cognitive, and behavioral challenges. One common issue associated with TBI is binocular vision dysfunction, which can significantly impact an individual's quality of life. In this article, we will explore the relationship between TBI and binocular vision dysfunction, the symptoms of binocular vision dysfunction, how it overlaps with the chronic symptoms of a TBI, and how prism glasses can help alleviate these symptoms.

What is Binocular Vision Dysfunction?

Binocular vision dysfunction is a condition in which the two eyes are not aligned correctly, resulting in a lack of coordination between them. This can cause a range of problems, including double vision, difficulty reading, and poor depth perception. When someone with binocular vision dysfunction attempts to focus on a specific object, their eyes may move independently of each other, causing images to appear misaligned or overlapping.

Binocular vision dysfunction can result from various factors, including genetics, eye muscle imbalances, and certain medical conditions. However, it can also be a direct result of TBI, which can cause damage to the areas of the brain responsible for processing visual information.

How Does TBI Cause Binocular Vision Dysfunction?

TBI can cause binocular vision dysfunction in several ways. One common cause is damage to the cranial nerves that control eye movement, which can result in a misalignment of the eyes. Additionally, TBI can cause damage to the areas of the brain responsible for processing visual information, which can result in poor eye coordination and difficulty focusing on specific objects.

Symptoms of Binocular Vision Dysfunction in TBI

The symptoms of binocular vision dysfunction can vary depending on the severity of the injury and the specific area of the brain affected. However, some common symptoms include:

  • Double vision

  • Blurred or distorted vision

  • Difficulty reading

  • Eye strain or fatigue

  • Headaches

  • Dizziness or vertigo

  • Poor depth perception

  • Difficulty maintaining visual attention

These symptoms can be especially challenging for individuals with TBI, as they can overlap with the chronic symptoms of a TBI, such as headaches, dizziness, and difficulty concentrating.

How Prism Glasses Can Help

Prism glasses are a non-invasive treatment option that can be effective in alleviating the symptoms of binocular vision dysfunction in TBI. These glasses work by refracting light, which can help realign the images received by the brain, reducing double vision and improving depth perception.

Prism glasses can be prescribed by an optometrist or ophthalmologist who specializes in treating binocular vision dysfunction. The glasses can be customized to fit the specific needs of the individual and can be worn during everyday activities such as reading, working on a computer, or driving.


Binocular vision dysfunction is a common issue for individuals with TBI, and it can significantly impact their quality of life. However, prism glasses offer a promising treatment option that can help alleviate these symptoms and improve visual function. If you or someone you know has experienced a TBI and is struggling with binocular vision dysfunction, it is essential to seek the advice of a qualified optometrist or ophthalmologist to explore treatment options, including prism glasses. With the right treatment and support, individuals with TBI can learn to manage their symptoms and live fulfilling lives.
