Possible Health Concerns Associated With 3D Viewing
The world is getting all excited about 3D movie viewing and gaming and while it certainly sounds amazing, there may be some potential health risks involved, especially for younger children.
Those of you who plan to purchase the Nintendo 3DS for your kids or have a mind to bring 3D viewing into your home via a 3D HDTV and the PlayStation 3, should probably read this Audioholics article. You can form your own conclusions, but it talks about how humans utilize stereoscopic vision and how continued exposure to 3D video viewing could, theoretically, mess with that ability. Stereoscopic vision begins developing when we first start using our eyes, and most experts agree that it's complete by the time we turn six. That's when the nerves and muscles behind the eye are "fully formed and have learned to work in conjunction with the brain to respond automatically to visual cues that provide seamless depth of vision."
However, you may not know about strabismus:
"Unfortunately there’s a malaise in children that can prevent full stereopsis from developing, called strabismus. This condition is also called lazy-eye but has nothing to do with laziness; it’s an abnormal alignment of the eyes in which the eyes don’t focus on the same object and depth perception is compromised.
There is treatment for strabismus that involves helping a child’s nervous system to learn stereopsis, causing it to eventually become a natural response. But the ability to re-learn has its limitations, and treatment has been met with limited success beyond a certain age."
Recent medical evidence suggests that the nervous system "never stops learning and re-learing" so in other words, it's never too late to treat strabismus...while on the flip side of the coin, it's never too late to contract strabismus. The chances of contracting this illness lessens after the age of seven and - presumably - as we get older, but the risk may still be there. Just something to consider from a health standpoint.
Personally, I have no intention of over-indulging in 3D; I've always believed that might have some sort of backlash, like headaches or something.
