Is 3d tv harmful to you
While it’s early days for 3D broadcasting, it’s worth pointing out that there’s some evidence that prolonged 3D viewing experiences are bad for you. success of 3D movies such as Avatar and the insatiable desire of consumer electronics manufacturers to convince us to continually replace gear. so is 3d Tv harmful to you.

Research 3D TV Viewing
“People who are not able to appreciate the images in 3D books, would either be unable to appreciate the 3D in movies, or may develop unpleasant symptoms from watching them,” Dr Kowal said.
3D technology tricks the brain by showing different images to the left and right eye which are then layered together by the brain to produce a single 3D picture. Dr Kowal said more than 90 per cent of Australians had either near perfect or perfect 3D vision and would have no problems viewing 3D content.
Now, if you’re only going to watch the occasional event , that might not matter too much. But if you’re consistently watching 3D content, either via a dedicated channel or through a set which does on-the-spot conversion, it could be a major cause of concern.
