Binocular vision dysfunction
( BVD)
Binocular vision dysfunction ( BVD ) refers to trouble having both eyes looking at the same thing at the same time, seeing one single image that is understood and processed comfortably by the brain.
BVD can be caused by a number of eye conditions , some common ones are listed below:
– difficulty getting both eyes to point together on an object ( convergence insufficiency)
– difference in focusing ability between the eyes ( anisometropia)
– a turned or lazy eye from early childhood ( strabismus /amblyopia)
– disruption of previous visual ability through concussion / traumatic brain injury
– break down of comfortable visual function due to eyestrain ( common in screen users)
BVD can impact life. Symptoms of BVD can include:
– sore tired eyes
– double vision
– headache
– difficulty concentrating when reading
– struggling with learning / reading / screen use
– dizziness
– motion sickness
– light sensitivity
– poor balance
– difficulty with ball sport/ ball catching
The good news is that BVD can be assessed and treated. Treatment can be glasses with lenses that help the two eyes to work as a team. Filters and vision therapy are other tools that we can use to teach the visual system to work as an efficient whole with both eyes in play.
