London: Scientists have warned that 3D TV can disorientate the brain, causing eye strain, headaches, nausea and sickness.
And the closer you are to the screen, the worse you feel, making TVs more problematic than cinema screens.
Studies show that in up to 20 per cent of viewers it could even induce physical sickness.
In one experiment, researchers at Eindhoven University in the Netherlands asked 39 people who could see 3D to read some text on a screen from 10 feet away.
Seven of the group suffered symptoms that can lead to nausea, including double vision and eye strain, reports New Scientist.
“You cannot damage your eyes by watching [in 3D], but if you spend an excessive period of time doing so, you may get a slight headache because of eye strain,” the Daily Mail quoted John Lee, President of The Royal College of Ophthalmologists, as saying in a interview.
