Recent scientific research shows that major myth of 3D TV being dangerous to your health is not exactly true. Some experts aired a number of concerns. One of them was about the depth-of-field issue for your eyes. Some claimed that prolonged viewing can alter the viewer's depth of perception for up to several hours after they take their 3D glasses off, which could lead to serious accidents. Even Samsung, one of the leading 3D equipment manufacturers, clearly stated on their website a safety guidelines document, which has many precausions to 3D viewers.

These recent findings discovered that 2D actually causes more of a strain than 3D. It is understandable that like with anything else in human life, we should not want 3D TV excessively. Watching 3D television under normal conditions is unlikely to be damaging to the human visual system, scientists from The Vision Centre say.

Professor Colin Clifford of The Vision Centre and The University of Sydney, says it is very unlikely that 3D TV could cause any long-term harm, provided people only watched it for a few hours a day.

“For objects viewed beyond reading distance, the eyes are pretty much pointing in parallel and very little adjustment is required to see things in depth.” Since 3D TV is usually watched from a longer distance it is unlikely to affect how the eyes and brain perceive depth of field. “In actual fact, two-dimensional TV creates more of a conflict for our visual system than 3D TV, because we have to interpret a 3D image out of a flat screen, whereas 3D TV is just giving us a 3D picture.
