The phenomenon of 3D TV

The phenomenon of 3D TVThe phenomenon of 3D television has been question of its negative effect on the eyes, but scientists from The Vision Centre say that under normal viewing conditions it is unlikely to cause any damage to the visual system. Professor Colin Clifford of The Vision Centre and The University of Sydney explains the concept of 3D television to answer all doubts that one might have regarding its safety.

He describes the functioning of the eye by saying that our eyes are pointing almost parallel when viewing an object that is beyond the reading distance. The adjustments that the eyes make are found to be very little and similarly viewing a 3D TV from a suitable distance may not affect the eyes. He compares how VR goggles, which were used to provide the 3D effect earlier are different from the present technology of 3D TV.

He gives details as to how with VR goggles different signals were sent to each eye resulting in confusing brain’s processing and its depth perception. He further clarifies that since we are watching 3D TV from a longer distance it is unlikely to affect how the brain perceives depth of field.

However, Samsung one of the leading manufacturers of television has issued safety guidelines according to which long hours of viewing is not suitable for anyone under the influence of alcohol, pregnant women, the elderly, those who suffer from epilepsy and those who are sleep deprived. Professor Clifford also agrees that there has been little research on ill effects on 3D TV.

In a lighter vein he goes on to tell that viewing normal television with one eye closed acts as a poor man’s 3D TV. Irrespective of the differences in opinion about 3D TV, all scientists agree that excess of TV viewing should be avoided and young children must specially be protected as their whole system, brain and eyes are developing. Long hours of exposure to TV could strain their visual system and damage the way the brain interprets the normal environment
