the vision of children aged 4 ~ 6 has gradually matured, and the clarity of vision has increased. It can reach 1.0 at the age of 6, basically reaching the level of adults. However, because parents are often busy with their own affairs and ignore the care of their children, many children sit on the TV for a few hours, which will do great harm to their children’s eyesight. How to watch TV to prevent myopia? The following ten points need parents’ attention.

1. Avoid taking too long. Children are in a period of rapid physical and mental development. Watching TV for a long time every day can easily make the child’s nervous system and body tired, affect the development of physical and mental health, and affect the normal progress of learning and other activities. It is better for preschool children to watch TV within 40 minutes every day.

2. Avoid too close

preschool children always like to sit in front when watching TV. In this way, the child’s eyes are stimulated by the strong light emitted from the screen for a long time, which not only easily reduces the child’s visual acuity and adaptability, but also easily reduces the regulation function of ciliary muscle, and the lens gradually becomes convex, resulting in myopia. Generally speaking, when watching TV, it is appropriate to place the child’s seat 2.5 ~ 4 meters away from the TV.

III. avoid excessive volume

when preschool children watch TV, under the stimulation of high volume for a long time, it is not only easy to reduce the sensitivity of hearing and form bad hearing habits, but also easily lead to the decline of visual sensitivity. On the contrary, using a relatively small volume can greatly promote the development of children’s hearing, vision and attention.

IV. avoid too dark light. When watching TV, the indoor light is too dark, which will affect the development of children’s visual function and easily lead to myopia. When watching TV with children at night, don’t turn off the lights. Install a small red light behind the TV to protect your eyesight.

v. avoid incorrect sitting posture

when children watch TV, they sit askew. If they lean on the quilt or lie in their parents’ arms, they will easily deform and bend the child’s amorphous spine and form bad sitting habits.

VI. avoid watching

and

after dinner. Children watch TV after dinner, which easily transfers the excitement center of the child’s brain, and pays attention to the TV content, forming the stagnation of digestive juice secretion and food deposition, affecting the digestion of intestines and stomach. After dinner, let the child move a little and then watch TV.

VII. Avoid watching

while eating. Children eat or eat candy and melon seeds while watching TV. The food in their mouth is often not chewed enough, which easily aggravates the child’s digestive burden and affects their digestive function. For a long time, it is easy to form the bad habit of eating snacks.

VIII. Avoid watching TV about fighting and murder.

preschool children often watch fighting and murder films, which not only easily makes children nervous and afraid for a long time and affects their physical and mental health development, but also easily makes children curious and simulate, leading to the improvement of children’s adaptability to bad social phenomena such as fighting and fighting. Increased aggression and risk-taking.

IX. avoid TV autism

TV and video game consoles are very attractive to children. Children have poor analytical thinking and strong simulation. In the long run, children are only interested in TV programs and indifferent to the things around them. Their character becomes lonely. If it is serious, there may be an abnormal psychological state.

10. Avoid letting children lie down and watch TV

some parents let their children lie down and watch TV, thinking their children are comfortable. In fact, it is counterproductive, which is quite harmful to their children’s health. Some people like to watch TV in bed or on the sofa. They feel comfortable, leisurely and energy-saving. Their children also follow suit and lie down and watch TV. In fact, lying down watching TV has many disadvantages. This is because when lying down to watch TV, you should not only lean your head and side, but also tilt your neck and deflect your eyes.

and

in this way, the line of sight of the eyes and the TV screen can not be maintained at the same level, which needs to be adjusted with the eyes. A long time will cause spasm and contraction of the extraocular muscles and the ciliary muscles in the eyeball, resulting in eye swelling and pain, conjunctival congestion, tears, and even increased intraocular pressure, blurred vision and decreased vision.

if you often lie in bed or watch TV on the sofa, it will also make the internal and external rectus muscles and upper and lower oblique muscles of the eyeball severely tired and contract maladjusted, resulting in eye strabismus and other diseases. Young people’s body is in a period of development, which not only easily makes their eyes tired, but also easily causes diseases such as eye astigmatism.

in addition, when you lie down and watch TV, because most of the muscles of the body have been relaxed, the respiration and blood circulation in the human body have slowed down, the central nervous system of the brain has gradually entered a state of inhibition, and the brain’s thinking and memory ability have been greatly weakened, resulting in a serious imbalance between inhibition and excitement, which not only can not achieve the purpose of enjoying TV programs, It will also cause insomnia, neurasthenia, low back pain and other adverse consequences. Therefore, in order to ensure good health and prevent diseases, it is best not to lie down and watch TV, especially children.
