TV is in 2D but we see in 3D - how does this affect our brains?

Question

We watch TV in 2D but everything around us is in 3D. When we go to a 3D IMAX movie it freaks us out! Does staring at moving 2D images negatively affect our brains?

Answer 1

Not any more than looking at TV adversely affects your brain.

The unsophisticated think that their TV displays a moving picture, but you know it does not. The TV shows a series of still pictures, each slightly different from one another. The brain tricks you into interpreting these still pictures as motion.

So does an IMAX employ tricks to make the brain think it is watching three dimensions. No harm is done (except perhaps for the gullible minority that believes the flickering images to be the real thing).

Answer 2

TV is 2D and thats what we see, 2D. The illusion of 3D is from our brains. I doubt that watching 2d images does anything to our brains, as that is how we see everything.

Answer 3

When an image falls on our retinas from the 'outside world' it is actually two dimensional because the retina is 2D. So this must mean the brain builds the image back up into 3D to match the 3D world outside.

......Makes you wonder, makes you think.

Answer 4

No. We see the television itself in 3d along with our living room. We are able to comprehend the 3d from the 2d images because we are smarter than dogs... well, most of us are.

Answer 5

Not anymore than reading a page or looking at this screen does.
