You may have noticed that 3D is a popular concept right now, be it in the cinema, on telly or with a games console. Or you may not have noticed, because you’re one of the population who can’t see it.
The Eyecare Trust has been doing some research into stereoscopic 3D effects and has found that around six million Brits – between 10% and 12% of the population – simply can’t see the effect.
It’s a result of poor binocular vision, where a person’s brain can’t quite properly process the two separate images being sent to it by the left and right eyes.
“You may not have realised that you have poor binocular vision before, because your brain will often try to compensate for any visual inadequacies,” explained the Eyecare Trust in a press release.
“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,” added Trust member Dharmesh Patel.
