3D may be the industry buzzword of 2010, but did you know a major proportion of the UK population can't even see it?
Over six million British consumers have poor binocular vision, which means they either cannot see or have difficulty seeing the effects on 3DS or in movies such as Avatar.
The study comes from UK charity The Eyecare Trust.
It's more than you think,” Dharmesh Patel, chairman of The Eyecare Trust, told MCV.
About 12 per cent have 3D vision problems and you'll find a similar percentage worldwide.
I don't think there are any long-term negative impacts. But it can create really bad headaches and aches behind the eyes. For these six million people it's like taking the 3D glasses off, making everything all blurry. You can't see the image and that causes headaches, eye-strain and blurred vision.”
3D technology relies on our eyes' ability to work together to achieve a perception of depth.
Research shows more than one in ten of us have a visual impairment, where our brains cannot process individual images from our left and right eyes.
And Patel said there are potentially millions of people that don't even know they have visual problems.
3D is appearing everywhere and there's loads of people complaining that they can't see it,” he added.
There will be people who have not attended an eye examination in years and are probably unaware they have a lazy eye or something like that.
Some people won't even know why they can't see it. Sometimes something can be done, but it depends on the individual case.”
