Modern life can not be separated from the TV, but for children, unscientific TV watching can lead to vision, hearing damage, but also psychological behavioral abnormalities. So how to let the children watch TV is more scientific? The first is the time to watch TV, the younger the age, the less time to watch TV should be. There are two concepts here, one is the time of each continuous television: generally speaking, less than 1 year old infants, each time to watch television should be less than 10 minutes; 2 years of age of young children less than 20 minutes each time; 3 years of age and older children less than 30 minutes each time. Another concept is the cumulative amount of time spent watching TV per day: less than 30 minutes per day for children under 3 years of age; and less than 60 minutes per day for children over 3 years of age. The second is the distance of the child from the TV set when watching TV. Generally should not be less than the size of the TV × 0.1 meters. Such as 29-inch TV, the distance should be 29 × 0.1 meters = 2.9 meters. Should let the child is basically facing the TV set, and the TV set skewed angle is not too large. The third is the environment and position of watching TV. Watching TV room to turn on the lights, do not make the environment bright and TV has obvious contrast; then pay attention to the posture of watching TV, parents should be a good example, to sit and watch, do not lie down, reclining to watch TV; TV set placed at a height of the children’s line of sight should be basically parallel to the children, young children can adjust the height of the seat; the environment should be comfortable, ventilated, do not have other noises or loud noise, the TV’s sound should be appropriate, not too high or too The sound of the TV should be appropriate and not too high or too low. The fourth is the content of the TV program. 3 years old children, the content of the TV should be soft lines, bright colors, beautiful pictures, simple stories. Don’t give children too much jumping, impact or stimulation of the screen. 3-year-old children can watch some story cartoons, or children can accept the nature, knowledge programs according to their preferences. Parents can also be adjusted through the television program to correct some of the child’s behavior, such as particularly active, aggressive children, you can choose the storyline soft or knowledge-based programs, and should not be too much to watch those with the fight, stimulation, impact of the violent television programs. The fifth is the way of watching TV, which refers to whether or not there should be an adult accompanying and explaining when watching TV. Here we will have parents accompanied called “parent-child viewing”. Generally speaking, it should be parent-child viewing and independent viewing. The younger the child, the higher the proportion of parent-child viewing time should be, so that the child’s age can give explanations to the TV screen to promote understanding. As children get older, they should be trained to watch independently and think for themselves, giving explanations only when necessary. You can also let your children talk about what they have watched and their opinions after watching TV, but do not force your children to summarize what they have watched after watching TV to avoid pressure and resistance. Then there is not to leave the child in front of the TV set parents walk away and use the TV to coax the child. Finally, after watching TV, let your child move their body and rest their eyes, it is best to go outdoors. Regularly check your child’s refraction and vision, and minimize TV viewing if they are nearsighted.
