Children and Binocular Vision Dysfunction
Could it be my child’s eyes?
Does your child suffer from anxiety, dyslexia, headaches, reluctant reader, ADD/ADHD?
Your child might be suffering from Binocular Vision Dysfunction (BVD). With BVD, one eye sees an image differently (vertically, horizontally or both) than the other eye. The body corrects this by overusing and severely straining the eye muscles, causing the symptoms of BVD which include headaches, blurry vision, dizziness, difficulty with reading, learning and concentrating, and even anxiety in large spaces like malls.
Why Does BVD often go Undiagnosed in Children?
When children enter school, they are given a standard vision screening. They are tested to determine how well each eye can see (visual acuity). You know the one—cover one eye, read the eye chart...cover the other eye, read the eye chart. However, they are not tested to see how well their eyes work together as a team (binocular vision) to identify any eye misalignment and double vision. The schools and pediatricians do not test for small amounts of misalignment. They also do not test for near vision which is when most symptoms occur with BVD. Any amount of eye misalignment can lead to reading and attention difficulties. Since BVD may affect up to 50% of children diagnosed with ADD/ADHD, reading and other learning problems, it is critical to test for even small misalignment amounts.
