Binocular Vision Dysfunction (BVD) is a condition where the eyes are slightly misaligned and the eyes struggle to send one clear image to the brain.
BVD can cause a variety of symptoms such as dizziness, motion sickness, headache, and light sensitivity.
If you experience any of the symptoms listed above, the Find an Eye Doctor directory provides a list of eye doctors near you that may be able to help diagnose and discuss treatment options for BVD.
Symptoms of BVD
BVD symptoms can interfere with a person’s ability to function on a day-to-day basis. Doing basic tasks, such as driving a car or reading, can become difficult, due to motion sickness and results in life-changing anxiety and disorientation.

Treatment of BVD
While BVD is often misdiagnosed, once you have the right diagnosis there are treatment options that can eliminate the symptoms of binocular vision dysfunction.
BVD is successfully treated with specific optical lenses called ‘prism lenses’ and vision therapy.
Prismatic lenses work to correct the misalignment in your eyes by manipulating incoming light before it enters your eyes so that when the images from the two eyes reach the brain, the brain can fuse them into a single image.
The prisms in the glasses ‘trick’ the brain into thinking your eyes are properly aligned, causing you to see just one object and preventing eye muscle strain.
Patients with BVD are also often treated with a customized program of vision therapy. especially if suffering with dizziness.
Vision therapy is a program to improve the communication between the brain and the eyes, further supporting the visual system and alleviating the symptoms of BVD.
Usually, patients find that their symptoms gradually subside or completely disappear when they wear prescribed prism lenses, which can be even further helped by completing a program of vision therapy.
An eye doctor experienced in BVD can discuss the treatment options to help you effectively maximize your vision allowing you to get back to enjoying life to the max.
