3D Hurts Your Eyes 244

sajjadG writes "After experimenting on 24 adults, a research team at the University of California, Berkeley has determined that viewing content on a stereo 3D display hurts your eyes and your brain. This can supposedly cause visual discomfort, fatigue, and headaches According to the article, 3D content viewed over a short distance (like with desktops and smartphones) is more visually uncomfortable when the stereo content is placed in front of the screen. In a movie theater, it's the opposite: Stereo content that is placed behind the screen causes more discomfort than scenes that jump out at you. With the explosion of 3D-capable gadgetry such as televisions and mobile phones, understanding just what this kind of technology is doing to our bodies may help us better use it in the future. The only problem is that technology tends to far outpace research, and until we get a better handle on its effects, we're more or less walking blindly into a 3D world."

    It's the emotional hurt that kicks in when you realize that odds are high that the movie you're seeing in 3D wasn't actually filmed in 3D and instead was faked so they can rip you off for an extra 5 bucks on your movie ticket.

    I think.

    First of all, there's no way to know if two things are separated by a volume of space unless you have a headache. That's how evolution works: the cerebral nerves were caused to evolve specifically by Darwin in order to function as a kind of animal cruelty version of Pavlov's dog in which mapping three-dimensional space actuates the occipital squinting reflex, causing us to narrow our eyes meaningfully at expansive vistas while also wishing for acetylsalicylic acid and a glass of water.

    Scientists consider this sort of thing basically self-evident, like the existence of atoms or Jenny McCarthy.

    Furthermore, the so-called Disney Cortex is capable of parsing dimensionality exclusively through parallax; in effect, the neck pain caused by this subtle lateral shifting of the head is conveyed via the uvula directly into the cranial brain-case, tapping into the same area of sensitivity exploited by the spatial depth pain discussed above.

    Elementary biochemisphology tells us that the only way stereoscopy can function effectively in the real world of fake entertainment is by pulling out all the stop and going holographic, so that the images can be processed and hurt us in as natural a way as possible. This is God's way of telling us that the Holodeck was cool.

    Fad researchers have understood this for centuries, since the time the Illuminati first started actively repressing news of the stereoscopic newspaper in 1743.

    Those are particularly harmful to the brain.

    How does this hurt the brain? Isn't it just the eyestrain that gives the headache? I thought the brain itself had no pain receptors.

    Mostly it hurts your eye, neck and facial muscles ( a 'tension' headache). Besides, at least for males, the brain clearly has pain receptors. Go kick some guy in the nuts and see what happens.
