Visual Description of Binocular Vision Dysfunction

Visual Description of Binocular Vision Dysfunction

  1. People suffering from Binocular Vision Dysfunction have a small amount of eye misalignment (shown by the black arrow) that causes the image (dotted red arrow) to not be on the center of the back of the eye (the fovea (the big red arrow head)):

  2. They overuse and strain their eye muscles to correct the misalignment:

  3. Now the image is on the fovea, but the overused and strained eye muscles cause the many symptoms of Binocular Vision Dysfunction.Diagram 3 - BVD - Visual description of Binocular Vision disorder

  4. While the body is doing the best it can to fix the eye misalignment, this approach causes a lot of problems. There has to be a better way to get the image onto the fovia without needing to reposition the eye. And there is!

  5. Since 1995, our doctors have performed groundbreaking research into the use of prism (in green) which is at the heart of our AlignTM Lenses. Prism can bend beams of light, and can redirect the image (red dotted arrow) onto the center of the back of the eye (the fovea (big red arrowhead)) while the eye is in it’s original, slightly misaligned position (black arrow). Since there is no need to realign the eye, there is no overuse of the eye muscles, which markedly reduces or eliminates the symptoms of Binocular Vision Dysfunction.
