With the rapid development of my country's film industry, more and more 3D movies in cinemas, from American blockbusters to children's movies, have begun to put on the coat of 3D movies. However, for children, will watching a 3D movie hurt the eyes?
More and more parents and children have become regular visitors in movie theaters. Many parents find that most of the animated movies in movie theaters are 3D versions, and children often take off the 3D glasses and rub their eyes when watching them. Children cried out that their eyes were tired, and some parents began to wonder: Will 3D movies harm their children’s eyes?
Let us first understand that 3D glasses
3D glasses are actually a kind of polarized glasses. Generally, the human eye can only see the left image with the left eye and the right image with the right eye. 3D glasses use the binocular convergence function. The left and right images are superimposed on the fundus to form a three-dimensional visual effect, and the viewer's eyeballs are repeatedly focused (the process of visual focus leaving the screen and returning to the screen) to form a 3D picture, which will cause the cerebral cortex to overwork and trigger adjustment Sexual asthenopia, producing a feeling of dizziness.
Then, what impact do 3D glasses and 3D movies have on children? The effect of
3D glasses on children’s vision
Generally speaking, children’s eyeballs cannot be basically mature until they are about 12 years old. When watching a 3D movie, the human brain must mobilize and fuse the images collected by the left and right eyes.
will feel tired after a long time, and this kind of difficulty is even greater for children. Children's eyes and binocular vision function are not fully developed. Moreover, if the child is active, has difficulty concentrating, and is not used to wearing glasses, this kind of fatigue is likely to be more obvious, which is not conducive to the child's eye health. The impact of
3D movies on children’s eyesight
1, 3D movies have fast moving pictures and low light, which can easily lead to eye fatigue. The visual system of children before
is not developed. When watching a 3D movie, the ciliary muscles of the eyes will be adjusted one by one with the sudden distance and close lens, which can easily lead to visual fatigue, causing pseudomyopia, strabismus, amblyopia and other vision problems , Affect the normal development of the eyeball.
2, 3D glasses have loopholes in hygiene, which can easily cause eye diseases. The
cinema is a public place. At the end of each movie, the staff should use a special potion to disinfect the glasses, but there is no guarantee that all the projection halls will be disinfected one by one. Therefore, there may be a lot of fingerprints and oil stains on the 3D glasses, and even carry bacteria, which can easily cause the spread of eye diseases.
What should children pay attention to when watching 3D movies?
1. Try not to take children to watch the 3D movie intensively. The child's receptivity is still poor. If you want to watch a 3D movie, it is best not to watch it continuously for more than two hours, and try to choose the back row position.
2. Before watching the movie, reminds children not to touch the lens and the frame part with their hands. If you wear glasses, you should avoid friction between the lenses. You can wipe the lenses with a sterile tissue or alcohol sheet.
3. After returning home, carefully wash the child's face and hands , warn the child not to rub his eyes with his hands repeatedly, reduce the chance of infection, and look far or see some green plants to relieve eye fatigue.
