Who doesn't love the flashy 3D specs we all have to pay for at the Cinema when the kids want watch the latest Disney Movie. There's likely far too many of us that recall the flimsy cardboard cut out specs with the red and blue colored lenses that never quite made a proper fit to view the early attempts at three dimensional movies or " still " pictures.
Now, however, researchers have reported that you may not need to use both eyes to experience 3-Dimensional vision. It is claimed that just one eye looking through a very small hole is possible to experience the effect. For people who have stereo blindness, where mis-alignment of the eyes make it impossible to see in 3-D this could open up a whole new world. It is now thought by researchers in St Andrews that both eyes are perhaps not required to take two visual images that the visual cortex of our brains then provide a depth field for that allows the 3-D effect.
The study team have demonstrated for the first time, that the same ‘special way’ in which depth is experienced in 3D movies can also be experienced by looking at a normal picture with one eye viewing through a small aperture as similarly when we view in 3-D space and objects are experienced in the same way that ‘normal’ binocular vision allows. This makes it possible for those with only one eye, or have problems with their two-eye vision to experience the “compelling’” effect of 3D.
