See many 3D TVs causing illness

Scientists warn that a 3-dimensional (3D TV) television in the market may stun the brain, causing eye strain, vomiting and fatigue in viewers. Also, the more you sit near this new television screen, the more uncomfortable you feel with even more serious sitting near the screen in the cinema.

Currently, to watch 3D, the audience needs to wear a pair of specialized glasses.

According to the Daily Mail, recent studies show that 3D TVs have even caused physical health problems for 20% of people watching them.

In an experiment, researchers at the University of Eindhoven, the Netherlands asked 39 volunteers to wear 3D glasses and read some words that appeared on the screen from a distance of 3 meters. Seven of these people have experienced unpleasant symptoms such as eye strain, dizziness, and vision of a monochromatic object and want to vomit.

Earlier this year, the Royal College of Ophthalmology, the Society of Ophthalmologists and industry experts said it was necessary to study more about the long-term effects of 3D TVs. However, they acknowledge the short-term effects of viewing this type of television very clearly.

Viewers will be able to choose between two "active" and "passive" 3D TVs with the ability to display images in different ways.

"Active" TVs will be cheaper but require special "filter" glasses. The basic idea is, the TV displays the program in a series of fast rotating frames - the left eye, the right eye, the left eye, the right eye - changes with the speed that the viewer cannot even detect the process. going on.

To watch 3D, the audience must wear a pair of specialized glasses (costing 77.7 USD and operate on the energy of a small battery) to protect the eyes from the transformation of frames at high speed, copper With the image displayed on the TV, wirelessly connected to a television. The brain thus deceived creates a 3D image in the viewer head.

Meanwhile, "passive" technology is based on a special polarizing filter on television to divide the image into its left / right eye parts. Viewers can view the later split image using a pair of polarized glasses to create a simple, similar 3D image but the glasses are given to the audience to watch 3D movies outside the theater.

Dr. John Lee, Principal of the Royal College of Ophthalmology, said in an interview: "You cannot destroy your eyes by watching 3D, but if you spend too much time on fun. You can suffer a mild headache with eye strain. "

About 10% of the UK population has poor vision, which means that it is difficult for them to see 3D effects in movies and video games. Instead, they see blurry images and the consequences will be headaches and eye strain.

Experts recommend that children under 8 should not be allowed to use 3D glasses regularly because their eye muscles are still developing. To avoid troubles from lawsuits, some electronics makers have even issued warnings that watching 3D TV can cause " motion sickness, disorientation and eye strain ".
