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.

IronPatriotBecause gamergate death threats, rape threats and doxxing are SO SIMILAR to pointing out the facts and logical failings of gamergate.05/30/2015 - 11:29am
IronPatriotLet's see. Gamergate sends death and rape threats against innocent women, and goth skunk blames the victims for getting harrassed. I point out gamergate harrassment and victim-blaming, and the pro-gamergaters squeal that they have been harassed? LOL!05/30/2015 - 11:28am
WonderkarpAs a life long X-Men fan, I cant tell you how much this annoys me http://www.ign.com/articles/2015/05/30/between-the-panels-marvels-merchandising-problem05/30/2015 - 10:23am
MechaCrashOh, no, I totally agree with you that Iron is being a jerk and needs to stop, but isn't the usual GG suggesstion for harassment "just ignore it, grow a thicker skin, don't report it"?05/30/2015 - 9:22am
Conster...and even the more stubborn and annoying ones are downright pleasant when compared to IronPatriot's behavior. His behavior is harassment regardless of whether it's aimed at pro-GG or anti-GG people, and it has to stop.05/30/2015 - 8:55am
ConsterMechaCrash: is this about Goth_Skunk's complaint against IronPatriot? Because while I'm anti-GG and strongly disagree with a lot of the stuff the pro-GG people on here say, most of them disapprove of harassment, even if it's 'in the name of GamerGate'...05/30/2015 - 8:55am
MechaCrashMan, some people are just...so immune to noticing irony, you know? The mind boggles.05/30/2015 - 8:35am
InfophileBut hey, I'm not a mod here. It's up to them05/30/2015 - 7:36am
InfophileThat's really not conducive to a good discussion. It just puts people on the defensive. So yeah, I really think IP should try to hold back on that. I'm not sure a ban is in order unless they show they can't or won't change, though05/30/2015 - 7:36am
InfophileLooking through IP's recent posts, there are some that do add to the discussion. There are also a handful which add nothing and are just jabs or point-scoring. It feels like IP is treating the comments more like a battleground than a discussion, honestly05/30/2015 - 7:34am
MattsworknameAhh, that explains why I wasn't aware. I don't follow, like ,nor care for soccer05/30/2015 - 6:50am
Goth_SkunkThe top dog at FIFA.05/30/2015 - 6:49am
MattsworknameWhose Blatter conster?05/30/2015 - 6:42am
ConsterSpeaking of non-video games for a second, I'm seriously disappointed in people for re-electing Blatter, and disgusted by his speech afterwards.05/30/2015 - 6:32am
ConsterHe's at least 5 times as bad as GS.05/30/2015 - 6:31am
Goth_SkunkEIC of Gameranx apologizes for his recent conduct: http://ow.ly/NDBxn Frankly, I'm surprised this wasn't posted sooner.05/30/2015 - 6:31am
ConsterGS does have a point: IP, on his own, causes at least as much harassment, insulting, and holier-than-thou'ness, as all the pro-GG people on this site combined.05/30/2015 - 6:30am
WonderkarpI am not sure I agree that its Harassment, But I do agree that he doesnt bring anything to the conversation. Its too the point where whenever I see his name, I just Thumbs down and move on. Its all buzz words and accusations and rarely civil05/30/2015 - 6:22am
MattsworknameWell, best of luck on that, but im not holding my breath.05/30/2015 - 5:04am
Goth_SkunkI believe the time to pull the plug was long ago, but kept quiet knowing full well Iron Patriot cannot help themself. There is a mountain of evidence to support my claim. In my opinion, it is harassment, and it needs to stop.05/30/2015 - 4:35am
