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.

Andrew EisenI only know of him being annoyed that IGDA mistakenly hosted on its anti-harassment tools page a blocklist he was on. What else was he critical of?01/31/2015 - 2:19am
Goth_Skunk@WonderKarp: Given Rosario's outspoken criticisms of the conduct of the IGDA, I would not be one bit surprised if he's being strong-armed into silence in closed-door meetings. He's not towing the party line, after all.01/30/2015 - 11:38pm
MechaTama31EZK: Thank you! (And I was able to see that you did it, only because you did it. How appropriate! :)01/30/2015 - 11:37pm
Matthew Wilson@Monte Nintendo is a Japanese company though. consoles are dead in japan. ps sony is a international company, so they do not much care about Japanese sales much.01/30/2015 - 10:11pm
MonteOnly one generation ago nintnedo had the best selling console. They know their games are still popular and can move their hardware. They just need to focus on better gaming hardware and advertising (their youtube policy not helping)01/30/2015 - 9:58pm
MonteI'd expect Nintendo to keep making consoles, much like the gamecube i doubt nintendo will see the Wii U as a sign of the end for consoles. There are multiple reason why the Wii U failed a big one being marketting.01/30/2015 - 9:55pm
Wonderkarpwhen asked on Twitter, the Chairman said He couldnt comment at this time https://twitter.com/siloraptor/status/561284497275367424. still looking for facts01/30/2015 - 9:41pm
Wonderkarphttp://pressfarttocontinue.com/2015/01/30/igda-puerto-rico-closed/ this is what I have so far01/30/2015 - 9:27pm
Wonderkarpso allegedly, IGDA has closed their Puerto Rico branch. This comes after the Chairman of the Puerto Rico branch was blocklisted by Randi Harper. I'm trying to dig up more info on it. all I have is a link with some info, but its not cited.01/30/2015 - 9:27pm
Andrew EisenSo, kinda like the Wii U just with a GamePad that's portable?01/30/2015 - 9:13pm
Matthew Wilson@AE I hope they do a Ipad/iphone thing. make a home console/handheld where games are playable on both. that is what I would want from them.01/30/2015 - 9:00pm
Andrew EisenThat would be a shame but as long as I can play comfortably on my TV I'll probably be fine with whatever the future brings.01/30/2015 - 8:56pm
Matthew Wilson@AE I would get used to it. I do not think nintendo is going to do another home console , but I suspect a hybrid one. 1. they are doing worse than the gamecube. 2. the home console market is dead in japan. even the ps4 isnt selling there.01/30/2015 - 8:54pm
Andrew EisenAside from that (and the aiming isn't too smooth but it's turn based so it's not a big deal (maybe better with Circle Pad Pro or New 3DS?)) my only other quibble is I'd much prefer playing it on a console. But I say that about nearly every handheld game.01/30/2015 - 8:39pm
Andrew EisenFrom what I've seen of Valkyria Chronicles, this is significantly slower. Mechanically, it's fine and plays into the game well. It just takes too long.01/30/2015 - 8:37pm
Matthew Wilsonyup like VC it moves every enemy each turn one by one.01/30/2015 - 8:33pm
Andrew EisenI played most of the Codename Steam demo. Pretty neat so far but the enemy turn (it's turn based) takes way too long.01/30/2015 - 8:31pm
Goth_SkunkJust finished the first episode of Life is Strange. The writing is hit-or-miss, the lip-syncing is awful (but I can't fault an indie dev for that), but the chronokinesis mechanic is dynamite. Love the concept. Can't wait to play more.01/30/2015 - 8:23pm
