TV 3D technology is just starting gaining popularity, and now threatens to halt its development: Samsung warns against their own receivers displaying three-dimensional images. On the Australian website, the group came up a list detailing the drastic side effects of television viewing in three dimensions - in addition to visual difficulties talking about trembling muscles, cramps, nausea, and disturbances of consciousness.
In general, the manufacturer recommends that people with "poor physical condition" to give up the 3D. If someone is not an island, or drank alcohol, should also settle for a traditional, flat image.
Quite curious suggestion is not to set 3D TVs near the open stairways or balconies - caused by the loss of three-dimensional images of orientation in space can lead to serious injury. These - a bit crazy - terms of use receivers make us suspect that Samsung wants to protect themselves from possible legal consequences. In the U.S. for many years on various products appear strange directions ("Do not iron while wearing shirt"). On the other hand, shall likewise be credible studies which show that the 3D technology is not completely harmless.
To assess the depth of the observed scene, the brain not only uses the two images recorded by the two eyes. Their non-compliance is a crucial factor that allows to obtain information on depth, but there are also many other "3D guidance." For example, a man takes into account that some patching by other objects, light blur distant objects, the distribution of shadow, or perspective, and my own experience (about a telegraph pole seems to be less than standing near the person). In the real world, a sense of depth, resulting from differences of two images, and additional suggestions are not mutually exclusive - but in 3D films, this does happen occasionally.
When you watch a three-dimensional image on the TV eyes must be focused on the screen despite the fact that the real point of focus vision behind it. This conflict sometimes leads to irritation of the eye muscle apparatus. The same happens with the sharpness of the image inside the 3D is not the same as the real focus in three dimensions - especially when watching ódê looked after the three-dimensional scene. Focus is not adjusted like in the real world: Eye movement is not accompanied by trained "in the real world" accommodation, because there is no longer typical of the normal perception of the relationship between the sharpness of detail and the remoteness of the objects. Such incompatibility brain copes separating accommodation from the eye movement - and this leads to discomfort and fatigue.
If at some point the brain starts to get used to the separation of focus and accommodation and the levels of concentration on different vision viewer may begin to be missing in real life information about the spatial situation. Typically, such a "disorder of two-eyeness" disappear after a few minutes, but proponents of a theory does not rule out that in children there is a risk of permanent problems in the perception of "real" depth. As a result, frequent viewing of images in 3D can lead to loss of visual sense of spatial orientation.
Such problems with 3D screens are of course also discussed in international forums - a lot of institutes in Asia, Europe and the United States working on this issue. Working Group Organization for Standardization (ISO Image Safety Section) also deals with the potential hazards of artificial three-dimensional viewing of images. For now, however, was not a study on the long term effects of television viewing 3D.
