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.

"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.

PHX CorpI'm going to do a test stream later today, if anyone is intrested07/31/2014 - 2:40pm
Andrew EisenYes, I'm such a big Nintendo dork that I read Nintendo's quarterly financial reports.07/31/2014 - 2:09pm
Andrew EisenCool tidbit - Mario Kart 8 sales account for more than half of total Wii U software sales for the last quarter even though it was only available for the last third.07/31/2014 - 2:09pm
Andrew EisenStill a pretty cool promotion. Unfortunately for me, I'm not interested in purchasing Mario Kart 8 and I already owned or didn't want any of the free games on offer.07/31/2014 - 1:43pm
Andrew EisenInteresting that EU had 10 games to choose from while North America only had four.07/31/2014 - 1:41pm
MaskedPixelanteIt certainly worked, I probably would never have bought Mario Kart 8 if it didn't come with a free copy of Wind Waker HD.07/31/2014 - 1:14pm
Andrew EisenI imagine will see similar promotions like "Buy Mario Kart 8 get a download code for one of these specific games" but almost certainly not for all of its (however you would define) biggest releases.07/31/2014 - 11:24am
MaskedPixelanteI wonder if Nintendo is going to be doing "buy one get one free" promos for all their biggest releases going forward.07/31/2014 - 10:48am

ZippyDSMleeWouldn't they be able to afford and get done in a timely manner a general gba emluator for the 3DS? It seems to me if they want to make money off sales they need to do it.07/31/2014 - 7:25am
Sora-ChanAmbassador program, that's what I was looking for. Anyway the other games that have been made no longer exclusive to the early adopters got updates in their software. It'll only be a matter of time more than likely for the GBA to get the same treatment.07/31/2014 - 5:35am
Sora-ChanI might be naming it incorrectly when I say "founder" i mean the program for earlier adopters.07/31/2014 - 5:34am
Sora-Chanthe 3DS's GBA emulator was a rush job due to the founder program. No other GBA titles have been released on the 3DS yet. If/When they do get around to it, they'll more than likely update the emulation software.07/31/2014 - 5:32am
Zenemulator...it's not just a slap job that makes "some" work..they do it for each which is why they work so well. I would rather have the quality over just a slap job.07/30/2014 - 5:48pm
ZenMatthew there is a difference between "worked" and "accurate". You play the Nintendo VC titles they play as damn close to the original as possible. The PSP would just run them as best they could, issues and all. And Masked...EACH VC title has their own07/30/2014 - 5:48pm
MaskedPixelanteOnce again, the 3DS already HAS a GBA emulator, it just can't run at the same time as the 3DS OS.07/30/2014 - 4:54pm
Matthew Wilsonyou cant street pass in ds mode ether, and if moders can make a gba emulator that runs very well on the psp as I understand it. you are telling me that Nintendo devs are not as good as moders?07/30/2014 - 4:49pm
Zenperformance. Halo 1 and 2 worked great because they actually did custom work on each of them...just like Nintendo does now lol07/30/2014 - 4:08pm
Zenexisting hardware while the GBA has to be emulated completely. Same reason the 360 couldn't run most Original Xbox games correctly, or had issues because they just did "blanket approach" for their emulation which led to game killing bugs or horrible07/30/2014 - 4:07pm
ZenSora/Matthew: It's not just Miiverse, but the whole idea of streetpass and things like that would be affected if the OS is not running. And just because a 3DS game can be downloaded and run does not mean that GBA can as easily. Those 3DS games use the07/30/2014 - 4:06pm
