Of the three-year-old \"averted vision\" phenomenon

Parents is experiencing the \"strange\": children had two or three years old, but he took the toy, comic strip. Parents worry about children\'s eye anomalies.

Say it, do not blame. This child is called \"inverted\" is in fact a normal physiological phenomenon. Typically occurs in about 3 years old child.

Eyes like a camera, external objects of light, focused, in the retina (the equivalent of photographic film) formed on an image. This image transmission to the brain, through comprehensive analysis, image is correct is standing. Therefore, we usually observe and feel the outside scenes are erect image. Visible, people are standing in the vision is an adaptable function of the brain. However, due to the development of cerebral cortex in children under 3 years is also immature, lack of a comprehensive analysis of the ability, when he picked up the book when watching, retinal impression but is erect, these children often can\'t help but read. However, depending on the duration time is very short, and most often do not attract the attention of parents in children. With the improvement of brain function, depending on the phenomena would naturally disappear. Due to the relatively large individual differences, each child is not the same. But parents guide and correct, depending on the length of time can be shortened. In General, child care as needed to gradually disappear after a few months, some duration or longer.

In order to make children more quickly through stages, parents can give children more content explaining the pictures at this stage, let your child a building-block approach, playing upright animal, children establish the vertical concept as soon as possible.

Is there any way to prove that the original is a normal physiological phenomenon? There are.

United States psychologists sizhuodeng once wore a pair of special glasses similar to the camera, so he sees everything coming down. However, after about 4 days, he saw the scene and were erected. It turns out that he has adapted to the inverted image of the brain. But when he took off a special pair of glasses, images of his eyes was turned upside down. Then after a period of time, to resume a normal vision.

Why human eye\'s image to the brain upside down, why the brain is used to determine this image, up to now no one can understand completely.

It is interesting, really long as people in the world. , More than 30 years of Brazil men James Rebhorn, reading, watching files is down; he could see people walking, what you see is the first on the front foot. Get used to it, also did not affect his life and work.
