Why the 3DS Might Be Bad for Young Eyes

January 3, 2011 -

Nintendo has been playing it very safe with the 3DS lately, publicly stating that kids under six shouldn’t view the 3D effects and providing parental controls that will lock the handheld in 2D-mode.

Is there really any danger to children’s eyesight though?  After all, we naturally view the world around us in three dimensions so what could the problem be?

Speaking to NPR, Ahna Girshick, a vision researcher at New York University, explains it thusly:

A three-dimensional effect is created on a flat screen like a video game device or television by filming a scene with two cameras.

"Each camera gets a slightly different view, and that creates what's called binocular disparity," says Ahna Girshick, a vision researcher at New York University. Binocular disparity is what you get when you look at the world with two eyes. Each eye sends an image to the brain that sees the world from a slightly different angle.

"The brain is accustomed to processing that. And it creates this 3-D impression," she says. Makers of 3-D media are taking advantage of that. "So they're just piggybacking what's already built into our eyes and brains."

But there's a problem: We also get some information about how far away an object is by how much we adjust the lens in our eyeball to bring it into focus.

"So with a near display, like if you're looking at a TV and you are sitting up close, your eyes actually focus on the surface of the TV, and that's at one distance," Girshick explains. But if the TV is showing a 3-D image, your brain might think an object is far off in the distance, even though your focus is on the screen right in front of you.

"And these two systems are now in conflict. In the natural world they're never in conflict," she says.



There is currently no evidence that 3D visuals are harmful to anyone so it’s up to parents to heed and enforce Nintendo’s 3DS usage recommendations for their children.

AE: Better safe than sorry and all that but buying your kiddies a shiny new 3DS and forcing them to play all their games in 2D does strike me as a bit mean.

For some reason this made me grin. At least they get games with better graphics than the DS, though. Not like 3D is the only thing the 3DS has going for it.

Matthew Wilsonit is a video talking about why certain games/products/consoles do well, and others do not. he back it up with solid research.04/18/2014 - 3:56pm
Andrew EisenI'm not keen on blind links. What is it?04/18/2014 - 3:45pm
Matthew Wilsonthis is worth a whatch https://www.youtube.com/watch?v=MyXcr6sDRtw&list=PL35FE5C4B157509C904/18/2014 - 3:43pm
MaskedPixelanteNumber 3: Night Dive was brought to the attention of the public by a massive game recovery, and yet most of their released catalogue consists of games that other people did the hard work of getting re-released.04/17/2014 - 8:46pm
MaskedPixelanteNumber 2: If Humongous Entertainment wanted their stuff on Steam, why didn't they talk to their parent company, which does have a number of games published on Steam?04/17/2014 - 8:45pm
MaskedPixelanteNumber 1: When Night Dive spent the better part of a year teasing the return of true classics, having their big content dump be edutainment is kind of a kick in the stomach.04/17/2014 - 8:44pm
Matthew Wilsonhttp://www.giantbomb.com/articles/jeff-gerstmann-heads-to-new-york-takes-questions/1100-4900/ He talks about the future games press and the games industry. It is worth your time even though it is a bit long, and stay for the QA. There are some good QA04/17/2014 - 5:28pm
IanCErm so they shouldn't sell edutainment at all? Why?04/17/2014 - 4:42pm
MaskedPixelanteNot that linkable, go onto Steam and there's stuff like Pajama Sam on the front-page, courtesy of Night Dive.04/17/2014 - 4:13pm
Andrew EisenOkay, again, please, please, PLEASE get in a habit of linking to whatever you're talking about.04/17/2014 - 4:05pm
MaskedPixelanteAnother round of Night Dive teasing and promising turns out to be stupid edutainment games. Thanks for wasting all our time, guys. See you never.04/17/2014 - 3:44pm
Matthew WilsonAgain the consequences were not only foreseeable, but very likely. anyone who understood supply demand curvs knew that was going to happen. SF has been a econ/trade hub for the last hundred years.04/17/2014 - 2:45pm
Andrew EisenMixedPixelante - Would you like to expand on that?04/17/2014 - 2:43pm
MaskedPixelanteWell, I am officially done with Night Dive Studios. Unless they can bring something worthwhile back, I'm never buying another game from them.04/17/2014 - 2:29pm

NeenekoAh yes, because by building something nice they were just asking for people to come push them out. Consequences are protested all the time when other people are implementing them.04/17/2014 - 2:06pm
Matthew Wilsonok than they should not protest when the consequences of that choice occur.04/17/2014 - 1:06pm
NeenekoIf people want tall buildings, plenty of other cities with them. Part of freedom and markets is communities deciding what they do and do not want built in their collective space.04/17/2014 - 12:55pm
