Your eyesight is vital for almost every task you perform. Binocular vision lets you see a single image, despite having two eyes. Your brain undergoes an amazing, complex process to fuse two separate pictures into one in-focus image. For this to happen, your eyes need to be aligned perfectly and work in sync constantly.
Binocular Vision Dysfunction (BVD) occurs when your eyes are no longer able to work together as a team. This can happen even if you have 20/20 vision. Because of this, BVD is often misdiagnosed. That’s why it’s important to see a qualified, experienced eye doctor who can listen to your symptoms, assess your vision, and make an accurate diagnosis.
