12% Of British People Can't See 3D Properly

Oh dear. This whole "3D" thing will have a lot of trouble getting off the ground if research by Britain's Eyecare Trust is on the money.

"3-D technology relies on our eyes' ability to work together as a co-ordinated team to achieve an accurate perception of depth," the report says.

"However, more than one in ten of us (12%) has a visual impairment that means our brains are unable to correctly process the individual images that are transmitted to it via our left and right eyes. This leads to an inconsistency in viewing the three spatial dimensions (height, width and depth) required to enjoy 3-D films in all their glory."

I've heard this more than once, both from readers and from friends and family, who tell me that for one reason or another, 3D effects either aren't as strong for them, don't work properly, or don't work at all.

While this is a British study, I'd be shocked if the results weren't very similar across the rest of the Western world. And if that was the case, it certainly makes 3D a tough sell.

12% Of Brits Can't See 3D Properly – Research [Edge]


    8% of men and 0.4% of women are colour blind to some extent. http://www.iamcal.com/toys/colors/stats.php <<Source looks dodgy but it's backed up by plenty of places.

    That never seemed to slow down the colour TV.

      Or the huge reliance on subtle colour differences in video games. Seriously, being colourblind myself, it can be damn hard sometimes! And with the "brown on brown" colour scheme that many modern games use, it's not getting any easier. Nevertheless, we make do; I'm sure amblyopics can learn too.

      Probably because you don't need dicky glasses to watch colour television.

    the 2 channels of visual info that gets fed to the left and right eyes in 3d displays (eg with polarised glasses) are no different than how the eyes normally see things.. in the case of 3d displays, the 2 different channels are just adjusted in terms of parallax to create that artificial sense of depth.

    my left eye is slightly short-sighted and the 3d thing is slightly awkward at the start.. but the brain adjusts after a while, as it does when I see things normally, giving more weight to the right eye and ignoring the blurry left...

      Does that mean you get to wear a monocle?

      Coz seriously... that'd be awesome.

        that's what I keep telling everyone... I want a monocle :P
        then I need to get myself a tophat and we're all set to play monopoly haha

          I'm pretty much blind in one eye, and last week I got tested for glasses. The optometrist told me that there was nothing could be done for the bad eye... so I asked if I could have a monacle instead.
          she replied:
          "No. Because they went out of style about a hundred years ago... and you'd look like an idiot".

    Sony and other 3D proponents may have an unlikely partnership with laser eye surgeons- a mutual backscratch opp if ever there was one...

    Anyone whose eyes are not equal of strength will have a certain difficulty in seeing the 3D images using this tech. We do compensate in the real world, but my depth perception might be pretty different to someone with normal 20/20 vision in the real world.

    I get a bit of a 'ghost image' after watching 3D movies for a while. Its similar to the effect if you open both eyes and put your hand an inch or two in front of one: you can sort of see your hand and see through it at the same time as your brain is seeing two different 'images.' Ive also never seen a 3D movie that makes me care. (I have used a 3D virtual reality cave that was a half-circle that encircles the viewer... that was pretty cool)

    I'm pretty sure higher percentages than that can't tell the difference between 720p and 1080p - or even SD and HD - and that high definition thing is doing okay.

    The difference is that 3D, as it's being positioned now, isn't something that's even supposed to get into 100% of homes any time soon. It's an option rather than a replacement, and I think it'll stay that way for quite a few years.
