Yes I read that too from him, makes him sound a bit arrogant, blame the user, instead of it's a limitation of the technology.
Their binocular vision can be normal during everyday activities and they can comfortably look at a stereogram or single 3D image, but they have difficulty in maintaining convergence and divergence of their eyes when watching a 3D movie.
That’s because a 3D movie requires our eyes to do something that does not happen routinely. In the real world we focus and aim our two eyes (converge or diverge) at the same location in space. For instance, we have to both focus and converge on our thumb to see it in 3 dimensions. However, in a 3D movie focus and vergence are completely separate. The only place in a 3D movie where anything is in focus is on the movie screen. However, independently of focus, the amount of disparity in an image pair signals the degree to which our eyes need to converge or diverge, providing the brain with an illusion of where an object is behind or in front of the screen respectively. How the brain and eyes try to reconcile this dissociation between focus and vergence is believed to cause discomfort in some people. However, this can often be treated through optometric vision therapy.
So basically he tells people to get vision therapy to untrain their eyes to work as they should in every day life...
He has interesting observations but this reeks too much of defending his own interests, Legend3D.
