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.

TechnogeekAnd speaking of harassment and Gamergate, Newsweek had a social media analytics company analyze the hashtag in the interest of finding out what the movement was really about. The results should surprise absolutely nobody at this point.10/25/2014 - 8:54pm
Neo_DrKefkaI was called a traitor for speaking out on harassment and I was put on a list for people on twitter to mass report me. Only GamerGate site that has come out of this that has been reputable would be TechRaptor. 2/210/25/2014 - 7:09pm
Neo_DrKefka@Neeneko The reason why I ended my support of #GamerGate was the fact KingofPol (The guy who was sent the knife) ended up saying crap about those with autism. At this point I confronted the community and some big wig writers on the #GamerGate side. 1/210/25/2014 - 7:08pm
NeenekoIt would also mean they have to confront that the sites already mostly cater to them and wiping that small percentage of otherness just does not justify new sites.10/25/2014 - 6:55pm
Neeneko@ quiknkold - problem is it has never been about freedom, it is about dominance, ownership, and priviliage. women and minorities should be the ones leaving and creating their own spaces, not them!10/25/2014 - 6:54pm
Neo_DrKefka@Mecha I hear you about KingofPol this is a guy who is using GamerGate to boost his career. Most of his streams are crap about him talking about him being drunk. What happened to him was wrong but it doesn't change the fact he has instigated much of this10/25/2014 - 5:40pm
Craig R.And I'll be perfectly happy in never seeing the phrase 'false flag' ever again, as it is one of the worst notions to ever come out of the camp of the tinfoil brigade that is already completely overused.10/25/2014 - 3:50pm
Craig R.Gone for a week and come back to find GG didn't go away at all. Dammit.10/25/2014 - 3:48pm
Matthew Wilsonif they were serious, they would go to youtube. most youtube game reviewers tend to revew games as product, and tend leave social issues out of it.10/25/2014 - 1:42pm
quiknkoldif the gamergaters were serious, they'd realize that Kotaku and Polygon arent the only games in town, and that with the freedom of the internet, they could create their own websites and achieve the goals they are trying to achieve without arguement.10/25/2014 - 1:35pm
james_fudgehe should have called the police.10/25/2014 - 1:20pm
TechnogeekAt least my statement still holds if it does turn out to be a false flag.10/25/2014 - 1:03pm
NeenekoThough I admit, since doxxing and false flag where heavily used tactics of the GG supporters, while they are not historical tactics used by detractors, I am skeptical how much it is really 'both sides' doing it in any real volume.10/25/2014 - 1:01pm
NeenekoOne thing that makes all of this messy is 'false flag' is a serious concern here. It does not help that the original GG instigators were also known for doing elaborate false flags to discredit feminism themselves.10/25/2014 - 12:59pm
MechaCrashThe guy who got the knife is the one who advocated doxxing, by the way, and was getting court documents about Zoe Quinn so he could publicly post them. It doesn't make what happened to him right, but he deserves no sympathy.10/25/2014 - 12:42pm
TechnogeekNo, that's a pretty shitty thing to do and I fully support the responsible parties getting a visit from the relevant legal authorities.10/25/2014 - 12:17pm
Neo_DrKefkaSomeone anyone tell me how two wrongs somehow make a right? This is becoming exhausting and both sides are out of there minds!10/25/2014 - 11:40am
Neo_DrKefkaSo two GamerGate supporters received a knife and syringe in the mail today. The same GamerGate supporters who said how awful it was were seen in other tweets gathering lists and sending our similar threats or harassment to shut down the other side....10/25/2014 - 11:36am
