Why do you feel dizzy when watching 3D movies?

When watching 3D movies, the fatigue of lens ciliary muscle caused by over-adjustment of eyes will affect the visual center, which will lead to posterior circulation ischemia and dizziness. At this time, patients need to close their eyes and rest to minimize visual stimulation. If necessary, you should go to the neurology department for electronystagmography and vestibular nerve function examination. After a definite diagnosis, they can use drugs to stabilize vestibular function, such as scopolamine, or take anti-vertigo drugs, sibelium capsules or Minzhilang tablets. You can also use Chinese patent medicines, such as Li Qiang Xuan Di tablets.

3D movies are composed of polarized stereoscopic movies. This technology will make people's left and right eyes receive different signals at the same time, resulting in a 3D effect. So after a long time, the brain will have hallucinations and even vomiting and dizziness.

Generally speaking, children's eyeballs will not mature until they are 12 years old. However, the dim light in the cinema and the rapid change of pictures in the movie can easily lead to eye fatigue. So watching movies for a long time is not good for children's eyesight health. Especially for children under 6 years old, the visual system is underdeveloped, and long-term viewing may cause pseudomyopia, strabismus, amblyopia and other visual problems.

Italy's Supreme Health Care Committee therefore issued a ban on children under 6 wearing 3D glasses to watch 3D movies. In addition, public 3D glasses distributed by cinemas may be stained with grease and bacteria, which is also a threat to health.

1. When watching a 3D movie, the viewing position should be as far away from the screen as possible, and at the same time, let the children take off their glasses halfway and have a proper rest.

2. Before watching a movie, parents can wipe the 3D glasses with a disinfectant to remind their children not to touch them.

After the movie, parents should remember to remind their children not to rub their eyes repeatedly, and remember to wash their faces and hands in time when they get home.
