Arnt Eyes one of the only thing on a human, that doesnt really change at all with age?

Ei. why children have big eyes (compaired to their faces),... and lateron in life smaller compaired to face size.

(like your nose/ears grow all through your life..... your eyes dont, they dont change, its why they are called the window to your soul).

But yeah... 3D can strain the eyes... and a child might not think to stop useing it, and listen to his/her body (not all adults do either).

I think its more about preventing the kids from hurting themselves than anything else.

I think it depends on the person, but I do think it could have a bigger impact on younger children than older people

Not sure though

Kids have been staring at screens for much of their lives and 3D tech is nothing new. We would already see the impact if it was really as bad as some believe.

Anecdotal evidence, but I sat very close to TV screens and handheld devices as a child and I am the only member of my family that had massive damage to my eyesight. I was 20/20 as a kid, 20/60 later and had as bad as 20/250 (nearsighted) before surgery. My eyes had stabalized at that point which is why I was allowed to get the surgery. Now I am 20/20 again after surgery. My entire family is 20/20 while I was nearsighted. I believe my eye strain sitting so close to the TV and gameboy made my cornea grow more than normal. Most people believe your eyes are finished at birth, but this is not true. Your cornea/eyes change shape into your mid 20s, and while overall changes are usually small they can make dramatic affects to your overall eye performance. 

Eyesight has gotten worse the last couple decades, with nearsightedness dramatically increaseing which would lead me to beleive the heavy increase of screen use do have an effect. Objectively, most doctors say they just cause strain and not long term affects, but I just don't agree. Perhaps this is too new a phenomenom to even really properly test being that tablets and such have only really existed in mainstream for a solid decade or two. My two cents. 

I am not trying to fear monger and I would say that its use is fine as long as they exercise their eyes in other ways and aren't playing games for 5-6 hours a day like I was as a kid. 

That article says nothing about simulated 3D visuals, or how a child's developing eyes could potentially be affected when repeatedly presented with unusual and unnatural stimuli. 

The following article talks about experiments that prove how our brains adapt our hand-eye coordination and spacial awareness based on what we perceive, by making the subjects wear vision-altering goggles.

https://www.theguardian.com/education/2012/nov/12/improbable-research-seeing-upside-down

'Images reach the eye in some peculiar fashion, and if that peculiar fashion is consistent, a person's visual system eventually, somehow, adjusts to interpret it — to perceive it, to see it — as being no different from normal.'

The subjects in the experiments were all adults. But young children's brains are still developing this adaptive skill; they're still developing their spacial awareness and coordination, and they're still developing their eye-muscles and eye-muscle movements.

While there's an obvious difference between goggles that flip someone's world completely upside-down (as described in the article) and looking at simulated 3D on a 3DS, they're still both devices that alter visual perception.

Until there's conclusive, scientific proof that features like simulated 3D do not impair the development of young kids' vision, eye muscles, visual perception, spacial awareness, coordination, etc., companies will most likely continue to protect themselves by putting warnings on products with this type of feature, and many parents will most likely continue to heed those warnings if they have young children.

Eye Damage is a low price to enjoy Nintendo's 3DS Masterpiece.

Dont knw abt 3d, but any long exposure to bright screen would damage eyes

The person I responded to claimed eyes were already being damaged by screens. I was just showing a source saying no proof of that.

A lot of products have warnings just to avoid getting sued, 3DS is a case of that. But we've essentially gone through the entire life of 3DS and still no evidence.

...yet. 5 years isn't very long to gather incidental data from thousands of kids and analyse short term / long term effects, check against control groups, different age groups etc. There's years of work needed to scientifically prove something one way or the other, and that's assuming that any work is going on to find proof at all.

Unless by 'no evidence' you mean a lack of sensational headlines such as 'Child struck blind by playing with the 3D slider up'.

If millions of people playing 3DS for much of your childhood hasn't shown some affects, then its probably harmless. Kids today in general are constantly looking at screens.

I also found it odd Kinect gave warnings about playing for long periods. Maybe they were concenred fat people were gonna have heart attacks.
