Just to clear the deck, I own no monkeys.
The Wikipedia article on Autostereograms (like the pictures in Magic Eye books) is really interesting. :)
Mechanisms for viewing [Autostereograms]
Much advice exists about seeing the intended three-dimensional image in an autostereogram. While some people can simply see the 3D image in an autostereogram, others must learn to train their eyes to decouple eye convergence from lens focusing.
Not every person can see the 3D illusion in autostereograms. Because autostereograms are constructed based on stereo vision, persons with a variety of visual impairments, even those affecting only one eye, are unable to see the three-dimensional images.
People with amblyopia (also known as lazy eye) are unable to see the three-dimensional images. Children with poor or dysfunctional eyesight during a critical period in childhood may grow up stereoblind, as their brains are not stimulated by stereo images during the critical period. If such a vision problem is not corrected in early childhood, the damage becomes permanent and the adult will never be able to see autostereograms. It is estimated that some 1% to 5% of the population is affected by amblyopia.
Of course, this begs the all-important question - Does this mean RSL can't see Magic Eye pictures?
In other news, more people need to ship Brian Williams/Jon Stewart. 'm just sayin'. And Fox News is stupid, but that's pretty much a given. :)
