There are risks/dangers attached to virtually EVERYTHING...

I'll only observe that cigarettes were once considered "safe" and even "healthy"... and the list is rapidly growing of "technological innovations" that aren't all they are cracked up to be, some of which IMO have the potential to endanger the continued existence of life itself.

Since I have serious physical reactions to some of the frankengredients now put in food for those people who have no willpower to push away from the table, I have certain reservations about anything "new and better". Just because a small sample over a short test period didn't show adverse effects, doesn't mean a darn thing... if you think for one second that those "studies" are always scientifically valid (IOW not influenced by the $$ involved), you're kidding yourself.

AND the reports of people experiencing discomfort or adverse effects ARE out there with the resurgence of 3D movies in the popular realm - it may be a small percentage of the overall population, but so is the canary in the coal mine...

Which reminds me, I REALLY want to go see Avatar in 3D!! I've heard it's good, and seems like it would be worth the theater experience... so what if I'm googly eye'd?

Maybe 3D porn really will send you blind? :-0)

As for the 3D Avatar experience, I highly recommend it. 3D technology has come a long way.

What I'm trying to figure out is that the 3D experience is instinctively wrong. something doesn't feel so perfect about it. Like Avatar for instance, we all saw it because it was a highly publicized event, which turned out to be good.

But how many Avatars can one take? A few years from now, when most blockbusters will go 3d, won't the glasses/single plane discomfort pop up again.

Watching pure 2D is okay and watching pure 3d is what our eyes do, but watching 3d on a 2d plane is something that we're not evolved to do.

Will they? I doubt it.

Optometrists would disagree with you. Here is a reference link: "Seeing Avatar Movie in 3D, How to See 3-D Eye Exercises, Magic Eye 3D, Stereograms, Stereo Views, Games, Puzzles, Lazy Eye, Cross eyed, Vision Therapy"

Hi Pavel
I've read the article and it stresses on how to improve your natural stereovision with 2D images which are static. You need to cross-eye for a few minutes and the image pops out from the 'noise'. This is different from live-action 3D footage on a 2D plane:
1. Interocular distance changes with the cut
2. Convergence changes sometimes even within a cut
3. You cannot focus on what you want - your focus is decided for you.

Just wanted to add that I have no personal problems watching 3D, except anaglyph (I hate my eyes seeing colors long after the film), but maybe tests need to be done, and maybe we are the test subjects!

Andrew Smith · February 23rd, 2010, 01:02 AM

The seeing different colours afterwards will be as a result of the plasticity of the brain, and hence some temporary "brain training" during the anaglyph encoded movie whereby your brain adapts to what the eye is receiving.

Nothing you won't recover from. It won't be permanent.
