Struggling with your new eyeglasses or seeing better when covering one eye? If you’ve been to multiple doctors and tried countless treatments but still experience double vision, shadowed or blurred images, or light sensitivity, you may have Binocular Vision Dysfunction (BVD). BVD is often the hidden cause of frustrating vision problems that interfere with work, family life, and daily activities—and it can be treated.
Causes of Vision Impairment and Double Vision

Binocular Vision Dysfunction & Vision Impairment Relief
Your vision is determined by more than just your eyesight. The alignment of your eyes also plays a pivotal role in your vision. Binocular Vision Dysfunction occurs when there is a subtle misalignment of your eyes. When left unchecked, this misalignment can result in the following vision impairments:
- Double Vision: A condition where a sufferer sees two images instead of one when looking at an object. With double vision, you may see a second image that is next to, on top of, or on the diagonal from the first image because both of your eyes are not able to focus on the same spot. When standard treatments do not treat your double vision, vision misalignment might be the cause. By treating your misalignment with our specialized aligning lenses, the object will be brought into focus allowing you to see a single, clear image.
- Shadowed or Blurred Vision: Having shadowed or blurred vision is the mildest form of double vision. When your eyes are even slightly misaligned, you perceive the image as having shadowed or blurred edges. As the misalignment worsens, the separation between the two images increases, causing the images to overlap or double. By treating your misalignment with our specialized aligning lenses, we can enable your eyes to work together and see a single, distinct image.
- Light Sensitivity: A condition in which you feel as if it is too bright or that there is too much light in a normally lit environment. You may squint, wear dark colored glasses, or wear a visor while indoors. When your light sensitivity is caused by Binocular Vision Dysfunction you are experiencing some amount of shadowed or possibly double vision. Your brain interprets this as seeing extra light or glare, resulting in your light sensitivity. By treating your vision misalignment, we can provide you with light sensitivity relief.
- Difficulty Adjusting to New Eyeglasses: Before visiting a NeuroVisual Medicine specialist, many Binocular Vision Dysfunction patients have difficulty adjusting to new pairs of eyeglasses. Because your vision is misaligned, it is critical to line up to the center of the lenses to the position of your eyes, and in many instances, this does not occur. By taking into account your vision misalignment, a NeuroVisual specialist can provide you with specialized aligning lenses that will position your prescription correctly to your eye so that you can adequately adjust to your new glasses.
A visit includes a NeuroVisual Evaluation, which will determine the extent of your vision misalignment and use those results to prescribe the appropriate specialized aligning lenses for you. Unlike your standard eyeglass prescription, these lenses treat your Binocular Vision Dysfunction, along with any additional vision impairments, to allow your eyes to work together. By taking into account your misalignment, the lenses can provide you with proper vision impairment relief.
