What is Binocular Vision Dysfunction (BVD)?


Many people haven’t heard of Binocular Vision Dysfunction or BVD for short. Nevertheless, it is a surprisingly common visual condition that can cause patients to experience a range of unpleasant symptoms. The key characteristic of BVD is eyes that are slightly out of alignment, which means that they don’t work together as well as they could. Since the line of sight from one eye is a little different from the line of sight from the other, the muscles of the eye have to work much harder than they should to correct the alignment and achieve a single line of focus.

When you are looking around and taking in a wide area, this issue isn’t as pronounced. However, when you are trying to concentrate on something, such as a digital device, a book or a computer screen, the extra effort that is needed by the eye muscles can become painful, resulting in the symptoms that are associated with the condition.

We are delighted to be able to offer the diagnosis and treatment of BVD here at our office in Cave Creek, AZ. In the meantime, here is what you need to know about binocular vision dysfunction.
