  12. 12. 3D Vision Syndrome What constitutes a syndrome?A group of symptoms thatcollectively indicate orcharacterize adisease, psychologicaldisorder, or other
  13. 13. So is the 3D Vision Syndrome Really a Syndrome? Yes! Yes.The symptoms and signs consistently include:headaches, nausea, dizziness, a vision inducedsense of motion, diplopia, blurred vision andeyestrain; as well as a disconnect betweenaccommodation and vergence.
  14. 14. So is the 3D Vision Syndrome Really a Syndrome? Yes! Yes.Discussed even less is the psychological and cognitivedisconnect that occurs because of where we knowthe image to be (at the screen) and where weperceive it to be (inches from your face).

  19. 19. Optometric Vision Therapy… is a sequence of therapeutic proceduresprescribed and monitored by the doctor to developefficient visual skills and processing. It is prescribedafter a comprehensive eye examination has beenperformed and has indicated that vision therapy isan appropriate treatment option.
