Binocular Vision Dysfunction FAQs

What are the advantages of using glasses that contain aligning lenses in treating people with BVD?

  • Getting people feeling better more quickly. The average person experiences a 30-50% reduction in symptoms almost immediately, and a 70-80% reduction of symptoms by the end of treatment.

  • Duration of treatment is short. The average person usually completes the initial treatment in approximately 2-3 appointments over 6-10 weeks.

  • Non-invasive treatment. No shots, needles or surgery are needed - wearing glasses with aligning lenses is the treatment.

  • Reduction in medication usage. Once a person feels better, many of their current medications for dizziness, headache and anxiety can be reduced or possibly eliminated (under their doctor's supervision).

  • Reduction in consultations and testing. Once a person experiences a reduction or elimination of their symptoms, they will not need to seek other consultations, and they will need fewer X-rays, CT scans, MRI's and other tests.

  • Reduction in disability. Upon feeling better, some people have experienced enough of a recovery to return to work.

  • Improvement with other therapies. Once the person experiences a reduction or elimination of their headache, dizziness and/or anxiety, they often do better with their other therapies: obtaining a higher level of function; improving at a much faster pace; and completing therapies in a shorter period of time.

What age person can be helped?

People have to be old enough to wear glasses and tell (or show) the doctor how they feel. The youngest patient that has been helped was 8 months old. There is no upper age limit.

Do the symptoms of Binocular Vision Dysfunction tend to get worse over time?

Yes. As we age, our eye muscles age and the lens becomes stiffer. This makes it more difficult for the eyes to focus and to point in the exact same location to see a single image. This same aging process is also the reason many of us need help with reading at about 40 years of age.

Can Binocular Vision Dysfunction cause me to be anxious?

Yes. Some people may become anxious in crowds, large spaces, or while driving. Some people say the dizziness itself causes them to be anxious.

Can Binocular Vision Dysfunction make it difficult for me to drive?

Yes. Depth perception is affected, as is the sense of balance and equilibrium, all of which can make it difficult to drive.

Can you help patients with Traumatic Brain Injury (TBI)?

Yes. It is important that those with TBI be thoroughly evaluated by their doctor and brain injury specialists to find any other cause for their symptoms. However, if no other cause is found, and if they have the symptoms of Binocular Vision Dysfunction (see Symptoms of Binocular Vision Dysfunction handout) and if their score on the screening questionnaire (the Binocular Vision Dysfunction Questionnaire or BVDQ) indicates a vision misalignment, then these people can usually be helped.

Can I be helped even though my car accident was 5-10 years ago?

Yes. If a person has Binocular Vision Dysfunction, s/he can be helped regardless of the duration of symptoms. Some people have had symptoms for as long as 30 years and do very well with their new lenses.

Will I know at the end of the exam if the eye glasses will help me?

Most people can feel an improvement in their symptoms during the first visit. This indicates that the special aligning lenses will most likely lead to a significant lessening of symptoms when the treatment is complete.
