Binocular Vision Dysfunction describes any condition where the two eyes have difficulty working together as a team to create one clear image. This results in image misalignment. The body attempts to correct this vision misalignment by overusing and severely straining the eye muscles.
In people with normal binocular vision, their eyes work in tandem, perfectly in sync at all times, to send one clear, focused picture to the brain. However, in people with Binocular Vision Dysfunction, the eyes do not work together and are not perfectly synchronized - this makes it difficult for them to see one clear image.
When the misalignment is severe, it causes double imagery or double vision. However, in most cases, the misalignment is very subtle, historically making it difficult to identify. Even when the misalignment is small and physically unnoticeable, the symptoms can be debilitating.
