3D Displays May Be Hazardous to Young Children

3D is all the rage right now, with cinemas and home theatre equipment both beefing up with glasses-mandatory viewing. Even gaming on-the-go is heading that way too with Nintendo's upcoming 3DS handheld.

While 3D gives us a neat effect while watching Toy Story 3, taking the kids to see that one over and over again, and eventually when it's on Blu-ray Disc, isn't a good idea at all.

According researchers who have been examining 3D video for years, the exposing children under the age of seven could affect their vision in a bad way. You see, our 3D human vision relies on our two eyes sending an image to our brains, which then makes stereoscopic sense out of it. This gives us depth perception – something that our brains only fully develop by the time we hit six years old.

Some of us aren't able to fully develop stereoscopic vision due to malaise in children called strabismus, sometimes known as lazy eye. This condition is treatable by training the nervous system to 'learn' stereopsis.

More than 15 years ago, Sega was toying with a VR headset that would give the wearer 3D images near the eye; but following a test by the Stanford Research Institute (SRI) at Palo Alto California, Sega was warned that the peripheral should not be given to kids – a tough order given that the video game market at the time was catered to a younger audience. The project was ditched, and 3D VR headsets slowly disappeared from the market.

Now that 3D is back, bigger than ever, the risk is even greater for young viewers. Adults are believed to be mostly safe from 3D effects, though most will likely find that they reach a point of fatigue before long anyway.

    it makes sense. When I was a kid, kids used to actually play outside and be active. Most of the outdoor sports we played were in fact in 3D, and were quite hazardous. We would end up sore, sweaty, and in good physical shape. Definitely not something today's youth is ready for

    That's why 3D using special glasses is a bad idea. Holograms are the future.

    Of course it's got a bad effect, it alters what hits the retina.

    But in the meantime, has everyone forgotten that the 3DS' effect can be turned off?

    Yup, so if you don't want your kids playing in 3D just turn the 3d off. Simple as that. Also I remember having one of those 3d headset things lol. It was heavy enough putting it on.

    I can understand why active shutter glasses might cause harm, but not sure why VR and polarized lenses would.

    With active shutter, you actually prevent an eye from seeing the image it's not meant to see, so it doesn't really use the brain's stereoscopic function "properly". But other technologies send images to both eyes at the same time... is it because it causes the eye to focus on some "fake" focal point?

    Young children should be running around outside anyways.

    I think the issue would stem from the "tricks" movie makers use to make certain parts of the image jump way out of the screen (more then normal).

    Its not generating a true stereoscopic image as the brain would normally see. If your brain is still learning how to interpret stereoscopic images and it starts seeing unrealistic ones then it will start creating neurological paths for these special instances as if they were real. This could harm your normal visions interpretations.

    So if your brains pathways are already set, it won't bother you. If you're young and still building them then you could risk building ones tuned to movies and not real life.

That's why 3D movies has to be twice as bright as regular movies to gave you the effective brightness of regular movie.

I though they all used two projectors where each would have a different polarization (therefore my though that both eyes were getting an image, albeit a different one).

    I would say yes of course, because if my kid touched my expensive 3d TV i would smack him over the head....Hazardous Indeed
