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.

Matthew Wilsonthe lose of nn would not be good for us, but it will not be good for verizion/comcast/att in the long run ether.04/24/2014 - 2:16pm
Matthew Wilsonsadly yes. it would take another sopa day to achieve it.04/24/2014 - 2:13pm
NeenekoI am also confused. Are you saying NN would only become law if Google/Netflix pushed the issue (against their own interests)?04/24/2014 - 2:10pm
E. Zachary KnightMatthew, you are saying a lot of things but I am still unclear on your point. Are you saying that the loss of Net Neutrality will be good in the long run?04/24/2014 - 2:06pm
Matthew WilsonOfcourse it does I never said it did not.though over time the death of NN will make backbone providers like Google, level3 and others stronger becouse most isps including the big ones can not provid internet without them. they can peer with smaller isps04/24/2014 - 1:54pm
E. Zachary KnightMatthew, and that still plays in Google's favor over their smaller rivals who don't have the muscle to stand up to ISPs.04/24/2014 - 1:45pm
Matthew Wilsongoogle wont pay becouse they control a large part of the backbone that all isps depend on. if verizon blocks their data, google does the same. the effect is Verizon loses access to 40% of the internet, and can not serve some areas at all.04/24/2014 - 1:14pm
Neenekolack of NN is in google and netflix interest. It is another tool for squeezing out smaller companies since they can afford to 'play'04/24/2014 - 12:57pm
Matthew WilsonI have said it before net nutrality will not be made in to law until Google or Netflix is blocked, or they do what they did for sopa and pull their sites down in protest.04/23/2014 - 8:02pm
Andrew EisenGee, I guess putting a former cable industry lobbyist as the Chairman of the FCC wasn't that great of an idea. http://www.nytimes.com/2014/04/24/technology/fcc-new-net-neutrality-rules.html?_r=204/23/2014 - 7:26pm
Andrew EisenIanC - I assume what he's getting at is the fact that once PS3/360 development ceases, there will be no more "For Everything But Wii U" games.04/23/2014 - 5:49pm
Andrew EisenMatthew - Yes, obviously developers will eventually move on from the PS3 and 360 but the phrase will continue to mean exactly what it means.04/23/2014 - 5:45pm
IanCAnd how does that equal his annoying phrase being meaningless?04/23/2014 - 5:09pm
Matthew Wilson@Andrew Eisen the phrase everything but wiiu will be meaningless afer this year becouse devs will drop 360/ps3 support.04/23/2014 - 4:43pm
Andrew EisenFor Everything But... 360? Huh, not many games can claim that title. Only three others that I know of.04/23/2014 - 3:45pm

Andrew EisenI love RPGs but I didn't much care for Tales of Symphonia. I didn't bother with its sequel.04/23/2014 - 11:21am
InfophileIt had great RPGs because MS wanted to use them to break into Japan. (Which had the side-effect of screwing NA PS3 owners out of Tales of Vesperia. No, I'm not bitter, why do you ask?)04/23/2014 - 10:52am
