Parents and friends often think that it is a good thing to show their children educational videos in the morning, learn English through the screen, know shapes and know Chinese characters. What's the matter? I know that, regardless of age, unrestrained picture time will not only damage the eyesight of developing children and cultivate "quiet fat children", but also affect their cognitive function, putting them at risk of autism, introversion and social obstacles. The shortcomings of electronic products can not be ignored. Early exposure to electronic products will do harm to children's health and psychology.

1999 The American Academy of Pediatrics suggested that children over 2 years old can be exposed to multimedia such as TV. 20 1 1 American academy of pediatrics reiterated the recommendation of 1999. On the other hand, watching TV for a long time is easy to make children suffer from myopia. The diameter of a person's eyeball will affect his vision. Too short a diameter will cause hyperopia, and too long a diameter will cause myopia. Under normal circumstances, babies are in a primitive state because of their short eyeball diameter. In other words, Baidu's "original reserve" is often mentioned in the parenting encyclopedia. With the growth of children's age, the eyeball is more and more developed, and the diameter increases to a certain length every year. At the age of 5, his eyesight is close to that of an adult.

Electronic early education products are becoming more and more abundant. Is it education or Shanghai? Do you want to put an end to children playing mobile phones? In addition to pathological reasons, the baby's eyesight protection is poor, and the diameter increases too fast, so it can quickly consume the "original reserve" before the age of 5. In other words, before adulthood, the diameter of the eyeball has reached the adult level, but the child's body continues to develop. Of course, the diameter of the eyeball will continue to increase. If there is no original reserve, you can only be nearsighted next time. This is why myopia is particularly easy to occur before 18 years old, but the vision level will be stable after adulthood. Look at the eyes for a long time at close range, irritating light, etc. It is easy to cause visual fatigue and lead to excessive growth of eyeball diameter.

Knowing the main principle of myopia, we can easily understand that the unreasonable use of electronic products will increase the probability of children suffering from myopia. Electronic early education products are becoming more and more abundant. Is it education or Shanghai? Do you want to put an end to children playing mobile phones? On the other hand, premature contact with electronic products is easy to attract children's attention and social cognition. Christaki, a child behavior expert at the University of Washington, USA, has conducted many follow-up studies on infants watching TV. The research shows that every hour that children aged 65,438+0 ~ 3 watch TV will damage the attention of school-age children by 65,438+00%.
