Avoid TV In 3D To Cause Eyestrain, Headaches, Nausea

In one test, researchers at the University of Eindhoven in the Netherlands has asked the 39 people who could see the 3D to read the text on the screen from 10 feet away.

Seven of the groups have suffered from symptoms that can lead to nausea, including double vision and visual fatigue.

Royal College of Ophthalmologists said that more research is needed on the long-term effects of 3D TV, but admitted that the short-term effects were visible.

Viewers will choose between two types of 3D-TV - active and passive - that displays images in different ways.

Active TV is cheaper, but requires a special "shutter" glasses. The basic idea is that the television program, a series of frames in rapid alternation - the left eye, right eye, left eye, right eye - are changing so rapidly that the viewer can not even see what happens.

shutter glasses, which cost £ 50 a pair and is powered by a small battery, drown an eye or the other on the replacement chassis at the same high-speed sync with the image shown on TV through a connection wireless set. The brain is pushed to create a 3D image in the eye of the mind.

The technology is based on a particular passive polarizing filter on the TV to share the image in the left eye / right eye elements.

The image is split with a simple pair of polarized glasses - similar to those distributed in modern 3D cinemas - to create the 3D image.
