Abstract: electronic products have bright colors and strong visual stimulation. Using these electronic products close and for a long time is harmful to children’s visual development. Children’s eyeballs keep watching and adjusting for a long time, which is easy to lead to myopia over time. Sometimes dry eyes occur because of staring at the screen for a long time. After the
new year, the winter vacation also began to enter the countdown. Every winter vacation, without the constraints of school, many children play with mobile phones and computers at home for a long time, which can easily lead to myopia or deepen myopia. The holiday begins immediately. Parents should help their children do their “homework” to protect their eyes and welcome the arrival of winter vacation.
1. Control children’s exposure time to electronic products
electronic products have bright colors and strong visual stimulation. Using these electronic products close and for a long time is harmful to children’s visual development. Children’s eyeballs keep watching and adjusting for a long time, which is easy to lead to myopia over time. Sometimes dry eyes occur because of staring at the screen for a long time. Therefore, the time of using electronic products should be well controlled. It is recommended that the use time is about 20 minutes, and you should overlook and relax your eyes.
2. Increasing outdoor activities
research shows that outdoor exercise for two hours a day and 10 hours a week can effectively prevent juvenile myopia and reduce the incidence of myopia by 10%. The light intensity of sunlight is hundreds of times higher than that of indoor light. On the one hand, high-intensity light can reduce the pupil, deepen the depth of field and reduce the blur, so as to inhibit the occurrence of myopia. On the other hand, the stronger the light, the more dopamine is released, and dopamine can also inhibit the occurrence and development of myopia.
3. Observe the child’s abnormal performance and check
in the hospital in time. If the child likes to squint at objects, tilt his head to watch TV, read and watch TV close, or blink frequently, he should go to the professional eye hospital for visual examination as soon as possible.
children begin to have a comprehensive optometry every year at the age of 3 ~ 6, and establish refractive development files. Every child is born with “hyperopia”. With the increase of age and the cultivation of the habit of using eyes at close range, he slowly develops from “hyperopia” to “myopia”. Therefore, early examination of ocular axis, corneal curvature and visual acuity can take preventive measures to protect children’s “hyperopia reserve” from being consumed and effectively prevent the occurrence and development of myopia.
