Ok, this doesn't quite fit into any category on TPU and it's not general nonsense, but 3D is the next big thing and it affects anyone who's thinking of going 3D with their PC or TV, so I've put it under Graphics Cards. Perhaps we could have a new 3D graphics section?
This article talks about the dangers of excessive exposure to 3D displays and the potentially damaging effects of binocular dysphoria. In particular, it could potentially lead to lasting brain damage in kids. The author hopes that 3D TV dies a quiet death because of this problem.
I really like my nVidia 3D Vision, but has this effect on me too (feels odd and slightly disorienting and occasionally very mild 'virtual' nausea) leading me to want to dip in and out of it as on occasional treat, rather than get stuck in it for hours on end.

Virtual reality headsets use the same technique for displaying 3D as we find in movies or 3D television sets - parallax. They project a slightly different image to each one of your eyes, and from that difference, your brain creates the illusion of depth. That sounds fine, until you realize just how complicated human depth perception really is. The Wikipedia entry on depth perception (an excellent read) lists ten different cues that your brain uses to figure out exactly how far away something is. Parallax is just one of them. Since the various movie and television display technologies only offer parallax-based depth cues, your brain basically has to ignore several other cues while you're immersed in the world of Avatar. This is why the 3D of films doesn't feel quite right. Basically, you're fighting with your own brain, which is getting a bit confused. It's got some cues to give it a sense of depth, but it's missing others. Eventually your brain just starts ignoring the other cues.
That's the problem. When the movie's over, and you take your glasses off, your brain is still ignoring all those depth perception cues. It'll come back to normal, eventually. Some people will snap right back. In others, it might take a few hours. This condition, known as 'binocular dysphoria', is the price you pay for cheating your brain into believing the illusion of 3D.
