Recently, dandan (pseudonym), a little girl who is only seven years old, has always said that she can't see clearly when she looks at things recently, and from time to time with eye pain, Dandan's parents took her to the hospital.
The ophthalmologist gave the little girl a mydriatic refraction, and after examination, it was found that the myopia in the right eye was 625 degrees, the myopia in the left eye was 600 degrees, and the vision of both eyes was only 0.15. At a young age, the degree of myopia is as high as 600 degrees, what is going on?
According to Dr. Yang Yong of Shanghai Aier Eye Hospital, there are often six or seven-year-old children who suffer from myopia at a young age due to watching TV or playing mobile phones, but it is not common for people like Dandan to have more than 600 degrees of myopia.
Experts said that there are two types of causes of myopia in children in general, one is genetics, and the other is poor eye habits. Among them, poor eye habits account for the majority, and it is also the most common cause of myopia in children. In the case of Dandan, genetic factors account for a higher proportion, about 60% of which are myopia genetic factors, and the influence of acquired eye habits accounts for about 40%.
However, the problem of eye habits should not be underestimated, such as allowing children to watch TV too early, playing with electronic products such as tablets and mobile phones, such products have small screens, and long-term, close-up use can easily lead to excessive eye fatigue.
The LED backlight of iPads and mobile phones is very bright, 4 times that of ordinary computer screens. When very close to the eyes, the strong light will directly and concentrate on the human eye, and the pupil will continue to contract to adapt to changes in the light source, causing the child's eye adjustment to decrease.
And Dan Dan's parents themselves are highly myopic, and at the same time care about the child's education, afraid of the child losing on the starting line, very early to the child to report a variety of early education classes, for convenience, the use of computers, iPads to download a lot of early education films, every day with the child to watch together. Who knows, a few years later, the seven-year-old daughter is actually short-sighted.
"Myopia prevention and control, prevention is greater than control, of which family prevention and control is the key." Parents are the gatekeepers of children's myopia prevention and control, and they must guard the first line of defense. Dr. Yang Yong suggested that parents should make a winter vacation homework completion plan with their children in advance, and supervise the daily completion on time and quantitatively. And it is necessary to improve the efficiency of learning and avoid prolonging the time to do homework due to procrastination, so as to reduce the burden on the eyes. During homework, rest for 20 seconds every 20 minutes and look at a place 20 feet (about 6 meters) away; take a 10-minute break for 40 minutes per eye, and try not to do homework at night. When reading and writing, you should maintain the correct posture of "one foot, one punch, one inch".
In addition, scientific studies have shown that outdoor activities are an independent protective factor for myopia, and insisting on outdoor activities for 2 hours a day and more than 10 hours per week can effectively prevent the occurrence of myopia. During the winter break, parents can remind their children to increase the number of outdoor activities.
In fact, the prevention and control of myopia in children and adolescents is a scientific system, which not only requires professional knowledge in preventive intervention, functional examination, refractive correction, myopia prevention and control, but also requires scientific technical means. "It is recommended that parents regularly take their children to professional ophthalmic medical institutions for examination from the age of 3, so that myopia risk factors can be detected early, prevented early, and intervened early to avoid children from developing into high myopia," Dr. Yang Yong said.
In addition, ophthalmologists remind that the holiday is a high incidence of pediatric eye diseases, and parents need special attention. During the holiday period, we must protect children's eyes, pay attention to eye hygiene, prevent infection; avoid long-term contact with electronic products; combine work and leisure, rest appropriately, and go outdoors for activities. If you have any eye discomfort, please go to a professional eye hospital as soon as possible.
