Background
With the development of modern electronic information industry, various electronic products are in endless, and have been merged into thousands of households, and the contact between children and the electronic products is increasingly widespread. For example, children are addicted to playing mobile phones, computer games, watching televisions and the like at a very small age, so that the eyesight of the children is gradually damaged, the eyesight health of the children is seriously damaged, and much trouble and adverse effect are caused to the later development of the children.
The number of people with myopia of children in China is always on an ascending trend in recent years, and some children are already myopic before entering middle school. The reason for the myopia is, in addition to the heredity, the greatest factor of the myopia is eye strain caused by too much learning strength and visual impairment caused by long-term direct vision on a display screen in normal times. It is necessary to design a display screen control system for preventing myopia of children according to the common phenomenon of damaging the vision of children.
There are currently many ways in society to prevent myopia in children. For example, in reading and writing at ordinary times, children need to have correct postures, and the distance between the operation and eyes should be kept at a proper distance; the light is well adjusted, the light is too weak to increase the adjusting burden of the eyes, and the light is too strong to greatly stimulate the eyes; the reading time is controlled, the fatigue of eye muscles is easily caused when the reading time is too long, and children feel that eyes are sore and swollen, so that the eyesight is necessarily influenced for a long time; reasonable nutrition, strengthening exercise, strengthening physique, and the like.
Most of instruments for preventing the myopia of children in the current market of China are eye massage instruments, or different lenses for watching distant and close scenes are separately arranged on the same piece of glasses to prevent the myopia. In consideration of the habits of children at the present stage, under the condition of not conflicting the contact between the children and a display screen, the design of a display control system for preventing the myopia of the children is significant, the existing myopia prevention equipment usually neglects the prevention of strabismus, and needs to pay attention to the normal sitting posture of the children, the improper sitting posture can bring the problems of myopia and vertebra, and the physical and mental health of the children can be influenced if the content watched by the children through a television is not proper, so the problems can be considered when the design of the equipment and the system for preventing the myopia of the children is carried out, and the eyesight protection technology and the method for the children when watching the television are provided.
