The TV revolution to 3D could be scuppled because too many people have poor poor binocular vision.

UK-based charity Eyecare Trust has claimed that almost 12 per cent of Britons cannot view 3D images and these will be the people who suffer from headaches after viewing a 3D film. In a press release the Eyecare Trust said that some people's brains are unable to correctly process the individual images that are transmitted to it via our left and right eyes.”

Many are unaware that they have poor binocular vision because your brain will often try to compensate for any visual inadequacies. But it could mean that all the new gear from outfits such as Nintendo, Sony and Samsung, who are planning to launch a number of 3D products over the coming year, may be unsuitable for a large portion of potential customers.
