With 3D display quickly becoming the hot item these days, no one would have imagined the harmful effects it may have on our eye sight as well brain. This fact was discovered by a research conducted by the University of California, Berkley. The research was conducted on a group of 24 adults and the results revealed that our eyes have to constantly adjust to both the distance of the 3D as well the 3D content. These factors have been termed as “Vengeance” and “Accommodation” by the research team.
Martin S. Banks who is a professor of Optometry and Vision Science, wrote in an article ‘The Zone of Comfort: Predicting Visual Discomfort with Stereo Displays’, “When watching stereo 3D displays, the eyes must focus — that is, accommodate — to the distance of the screen because that’s where the light comes from. At the same time, the eyes must converge to the distance of the stereo content, which may be in front of or behind the screen.”
3D viewing on desktop or a smartphone is in fact more visually harmful when the stereo is placed in front of the screen unlike the case in the cinema theatre where the stereo content is placed behind the screen and is more visually uncomfortable.
This research could potentially have negative consequences for all those wanting to bring in 3D phones, the new generation TVs etc. It would be interesting to note whether user response to such products in future.
