© IMDB.com3D is the latest craze thanks to blockbusters like James Cameron's Avatar.
Electronics companies have been keen to see the technology in living rooms, but experts are already warning of a potential for adverse effects on our health.
It seems manufacturers too have their own concerns, warning viewers about dizziness, convulsions and disorientation.
Three-dimensional televisions create their images by flashing up to 60 frames a second onto the screen.
Those pictures are then converted into three dimensions by battery-powered glasses linked wirelessly to the TV.
Associate Professor Alan Brichta, who studies brain chemistry and balance at the University of Newcastle, says people who suffer sea sickness or car sickness are most likely to have problems.
"What we have to appreciate is that we're really tricking the brain into conjuring up these 3D images and so when you start tricking the brain, unforseen things happen or at least things (things) that we don't like happening," he said.
"Each person reacts to these things slightly differently. While we all experience the 3D image of the TV, what it does to us can vary on a person-by-person basis."
And Associate Professor Brichta adds the longer you watch, the longer you are likely to feel sick.
"If someone's looking at (these) images on a TV for eight hours a day, they'll get a kind of strange sense when they put them down and perhaps look at flat images on a normal screen," he said.
Manufacturer Samsung even warns on its website and in its user manual that watching 3D TVs has the potential to create dizziness, muscle twitches, confusion and convulsions.
It tells viewers to keep the set away from open stairwells in case they become disoriented after viewing.
It also says people with a family history of epilepsy and stroke should talk to their doctor.
The ABC approached Samsung for an interview but the company declined and instead sent a statement.
"The decision to post the safety warnings on the Australian website was one made by Samsung Australia as a responsible vendor," the statement said.
"All Samsung products go through rigorous testing before they are introduced into the market and all products come with safety warnings for optimum use and enjoyment."
But Associate Professor Brichta says the news is not all bad.
"After the initial five minutes, you kind of get used to it. I'm sure that actually happens with most people, but a small percentage will feel unpleasant," he said.
3D televisions hit stores last Friday and retailers have reported strong demand so far.
Associate Professor Brichta is not so sure the demand will last.
"If you think back to the 50s and 60s, in movies, they came out with three dimensions and that was a big craze to start off with but it quickly died out," he said.
"So the question really remains whether this 3D gimmick is going to last."
The reason that 3D technology didn't take off in the 50s and the 60s was that two color 3D was nowhere near as good quality as flat, 2D, full color video. Now that we have the technologies to produce vibrant and lively 3D images in full color HD, the only question is, what will it mean for digital media? Surely 3D screens will be reserved for things like home theatre systems, at first, but within a decade, half the computers and televisions being made will support 3D for gaming. It will be a specialty technology for quite a while, but it will trickle out eventually.
