Professor Robert Allison speaks to about effect of 3-D vision on humans

The future of entertainment is 3-D, wrote Discovery News June 8. Their article included comments from Professor Robert Allison, a researcher with the Centre for Vision Research and part of the York-led 3D FLIC project:

But while moviegoers have flocked to recent 3-D offerings, film fans also have had mixed reviews about their experiences, with some reporting headaches, nausea, vision problems and motion sickness. With 3-D leaping to the small screen, clinical researchers and tech experts want to know whether the special effect might damage eyes in the process.

“The problem with 3-D displays is that unlike the real world, only a subset of the information that normally informs us about the 3-D structure of the world is present,” said Robert Allison, a computer science professor in York University’s Faculty of Science & Engineering who specializes in 3-D vision and technology.

And processing that incomplete visual information does, in fact, impact our eyes.

Better technology is alleviating the problem.

Allison also noted that recent 3-D movies have gotten better at reducing eye strain by mimicking our natural stereoscopic vision. “People are becoming less gimmick-oriented in terms of 3-D content,” Allison explained. “There’s more emphasis on a comfortable viewing experience where stereopsis enriches the experience rather than defining it, and recent movies like Avatar or Up have been very easy on the eyes.”
