Ever since the device was first shown at E3, we've been under the impression that the Nintendo 3DS is too good to be true -- three-dimensional, portable versions of beloved N64 games? That's un-possible. The other shoe we've been waiting to drop might have just done so with Nintendo's recently released 3DS warning label; not only does it caution adults to stop using the device if they start to feel ill, it also says that children under six shouldn't use the handheld's 3D functionality at all, as it may affect the development of their poor, innocent eyes. This isn't quite as explosive a story as the mainstream media will likely make it out to be -- 3D display experts have long discussed the possible repercussions the technology has on eyesight. The worry isn't that displays like the one included in the 3DS will actually harm your vision, but that the way it "tricks" your eyes into seeing 3D might impair the way you actually see depth, which is, of course, the coolest dimension. Of course, there's no firm research confirming these worries, but Nintendo's playing it safe -- the 3DS' parental controls will allow parents to lock the device into 2D mode for their under-six progeny. But wait, I thought Nintendo said that the 3DS was bad for kids under 6!" Yes, Nintendo did indeed say that it could inhibit eye development for children that age. However, eye doctors are saying that there is very little science behind Nintendo's statement.   Dr. Lawrence Tychsen, a pediatrics and ophthalmology professor at Washington University has said that “The fact you’d watch 3-D in a theater or a video game should have zero deleterious impact whatsoever.”    Another doctor, David Hunter, ophthalmology professor at Harvard University said that there is "scant evidence" that 3D can impede eye development.    As the Nintendo 3DS nears its launch, people were baffled when the big N gave this warning to consumers. Nintendo has been hyping up its newest handheld with various press events, and to hear this bombshell was a shock. Luckily for the company, there is no evidence supporting the warning. However, when notified about this recent development, Nintendo stood by their warning: “Nintendo’s position is children 6 and under should not use the 3-D feature of Nintendo 3DS, and parents should use the Parental Controls feature to restrict access to the 3-D mode.” While there seems to be nothing to fear about 3D technology blinding the children, Nintendo seems to stick by their stance, if not at least for legal reasons.
