Are 3D TVs Dangerous? Some Experts Say Yes

The majority of people should really have no problem with 3D-TV’s no matter how many hours a day they look at the new sets, although those with existing vision problems may have difficulty to varying degrees. Viewing difficulty in the past with 3D was mainly associated with a number of technical guffaws, such as mis-registered left and right images in dual projected, polarized theatrical presentations, or trouble viewing red/blue (and other variations of anaglyph) on TV, magazines or even on film and/or digital projection. Registration problems were most prevalent in the 50′s, however, many over/under (Single strip 35mm where two images shared one 35mm frame) caused headaches for many due to mismatched or weak light on the screen, framing problems and, for the most part, mediocre filmaking (try JAWS 3D or SPACEHUNTER on for size) and, to a degree, a lack of competence behind the camera.

FYI, studios like Sony Pictures, as a leading example, are working very hard right now to avoid these pitfalls by training filmakers how to shoot these films properly, something that didnt quite exist in the 50′s and hardly in the 1980′s.

I also have dealt with a number of 3D head mounted displays in the past and noticed that a number of manufacturers never stopped making them.

Either way, I doubt that this movement is going to stop and doubt that any legislation will stop it either.

I agree with this, 3D TV make our brain broken slowly. It was not recommended for bought this kind of TV in the future. But i dont know about this will exist or not. Because some people thinks, new technology = must buy ( Without looking its negative side ).

There was a short piece in the Science Times section of the NY Times a while ago. They reported that the biggest cause of discomfort or disorientation in 3D movies was the conflict between the distance at which the eyes converge to register a virtual object in 3D (often partway between the screen and the viewer) an the distance at which the eyes are focusing to see sharp detail, which is always at the screen surface no matter where the virtual image is.

In the real world, of course, the focus distance and the converge distance are always the same, because we’re focussing and converging on a real object somewhere in space.

If this is indeed a big problem, it should tend to get better over time as the people producing 3D content get away from all the hyper-wow effects and work toward a more subtle, realistic 3D image. The biggest conflict between converge distance and focus distance comes when objects are flying out in front of the screen and into the viewer’s lap. As you get to a more realistic image, where most objects are near the screen surface or behind it, the demands on the eyes and brain will feel more natural.

You can actually experience some of this today: The 3D trailers for many 3D movies are full of extreme effects that make your eyeballs feel like they’re being pulled out of your head, but then when the feature starts (at least if it’s something well-shot like “Avatar”) the visual experience feels much more natural and easy to take.

Oh well, on to plan B. Panoramic TV!

I have very little, if any, binocular vision, and the first time I saw a 3D movie, I got so dizzy and nauseous that thought I was going to die! (Cut me some slack; I was only 9.) This could be very bad for people who don’t know that they have depth perception problems.

I just spent 7 hours in the hospital ER after watching a couple of scenes from “Monsters vs Aliens” on a 3D set. I had to call 911 for an ambulance because I was vomiting uncontrollably and barely able to sit up.

There is no way in HELL these things are safe. Just because you’ve tried it and suffered no apparent ill-effects in no way proves you’re immune to them. I consider myself a “canary in the coal mine”. Learn from my horrific experience and don’t risk bringing on a similar nightmare yourself.

Who are you gonna believe? People posting here saying the “majority of people wont have a problem” or a technically qualified Expert? This just the movie industry trying again to make people buy everything over again but this time “on 3d”!! haha and most suckers will fall for it just to have bragging rights – just like DVD, when it arrived. Talk to me when they make a holodeck. Until then 3d is just a gimmick, an UNSAFE one at that.

i love binoculars that are made by Bushnell, they are really very high quality`’:

I use 3D anaglyph glasses (red/cyan) on occasion when I play computer games. I have suffered no ill effects. I keep the time I play below 2 hours. Since some people have problems with this, and others do not, the 3D industry should not be shut down. 3D games and movies and the like should have warnings that some people have adverse reaction to 3D. For an example, look at the photosensitive seizure warnings in computer game manuals.

God is in the T.V.

3D glasses drop sharply in price. In addition to the much lower whole-set price, the 3D TV also come with a more reasonable price for 3D glasses – reduce from hundreds of dollars to several dollars. For a family of three, less than one hundred dollars could cover all the supporting facilities previously worth 400-500 dollars.

ever see those new 3d cameras? that dont require any glasses? I tried to look at the screen of one I totally felt eyestrain and it felt like I was going cross-eyed and now theyre trying to make tvs require no glasses? NO THANKS! ill stick to non 3d devices.
