Binocular vision dysfunction (BVD) is a visual condition where the eyes are not completely in alignment.  This puts heavy strain on the eyes because the eye muscles are constantly trying to correct the misalignment to achieve single vision that is in clear focus.  This eye misalignment can be something that you were born with or it can be acquired from a traumatic brain injury or concussion.

One of the most common forms of BVD is known as Vertical Heterophoria.  Click here to learn more about Vertical Heterophoria.

The Symptoms of BVD and Vertical Heterophoria vary and some individuals may suffer from just one or a combination of them.  You can read more about the symptoms of BVD and Vertical Heterophoria by clicking here,.
