It’s important to schedule a comprehensive eye exam once a year to keep every aspect of your vision healthy and functional - including binocular vision. Monitor your vision with regular eye exams Prism glasses (prisms built into eyeglass lenses)Įvery treatment has the goal of getting the eyes to work together in a more efficient manner and maintaining single, clear vision. The eyes are checked very carefully as misalignment associated with BVD may be very obvious or very subtle. If a refractive error such as myopia (nearsightedness), hyperopia (farsightedness) or astigmatism is present, glasses or contact lenses will be prescribed as the initial treatment. The first step in any vision treatment is to correct refractive error. Trauma and traumatic brain injury (TBI), such as a stroke or concussionĭiagnosis and treatment for binocular vision dysfunction (BVD)īefore beginning treatment for BVD, your eye doctor will evaluate your entire visual system. There are a few main causes of BVD, including:Įnvironmental stress on the visual system SEE RELATED: Vision problems can be misdiagnosed as ADHD or ADD Causes of binocular vision dysfunction (BVD) (And don’t hesitate to also consult your primary care physician about ADHD symptoms.) A pair of glasses or additional treatments could make all the difference if the problem is vision-related. Since the symptoms of BVD and ADHD are so closely related, it’s important to have an eye exam to investigate the function of your binocular vision. In school classrooms, excess visual stimulation can be more of a distraction than an enhancement to their education.Īdults may also struggle with similar symptoms while at work, driving or in various public spaces. A child whose eyes are misaligned may have trouble concentrating, reading and writing because it is physically difficult for them to do so.

The testing process for binocular vision dysfunction is very detailed and sensitive in order to properly identify issues and determine a proper treatment plan. The misalignment associated with BVD may be very obvious or it may be very subtle. Vertical strabismus, such as hypertropia (upward eye turn) or hypotropia (downward eye turn).Ĭonvergence insufficiency, in which the eyes tend to point outward during near work.Ĭonvergence excess, in which the eyes tend to point inward during near work. Horizontal strabismus, such as esotropia (inward eye turn) or exotropia (outward eye turn). Some examples of common binocular vision problems include: This type of error is called binocular vision dysfunction (BVD), and it involves either a vertical or horizontal misalignment in the eyes. When the eyes don’t work together as a team, it is hard for the brain and visual system to produce a single, clear image. SEE RELATED: What part of the brain controls vision? Binocular vision dysfunction (BVD) This may result in eye coordination problems and conditions such as: Some people struggle with depth perception and eye alignment, which can interfere with achieving stereopsis. When a complete, single image is projected in front of you through this eye-to-brain communication, it is referred to as stereopsis (depth perception). This information is then sent to the brain, which compares and processes the different images into one single image. In binocular (two-eyed) vision, each eye sees an object from a varying angle. The process also provides for a wide field of vision and precise depth perception. In functional binocular vision, these two pathways fuse together to create a single, clear image. (If you break down the word, “bi” means “two,” and “ocular” means “eyes.”)īoth the left and right eye have their own line of vision. Binocular vision describes the way the two eyes work together to integrate images seen by each eye into one image.
