New research has shown that a large proportion of Brits have poor binocular vision and the benefits of 3DTV are lost on them as a result.
According to the study, which was carried out by the Eyecare Trust, six million UK residents cannot perceive the 3D effects of modern gaming consoles and TVs as a result of poor depth perception.
Speaking to games magazine MVC, Dharmesh Patel, chairman of The Eyecare Trust, said poor binocular vision affects far more people than you might first expect.
"About 12 per cent have 3D vision problems and you'll find a similar percentage worldwide," Patel told the news provider.
He added: "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."
He said that poor binocular vision can be the result of a condition known as lazy eye - which can be spotted quickly and easily by a qualified optometrist or ophthalmologist.
However, according to Patel, millions of people are completely oblivious to the fact that they have vision problems.
He said: "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."
Recently, the Daily Mail reported that six-year-old Ben Michaels was encouraged by doctors to play computer games for two hours a day to cure his lazy eye syndrome.
