If the child can see the blackboard clearly, then there is no problem with his vision? The "stubborn" parent regrets it

He had always been able to see the blackboard clearly before, so how could his eyesight be affected? Ms. Jin was very puzzled when she saw her son's medical report.

At the end of September, 10-year-old Fan Fan (pseudonym) was diagnosed with poor eyesight during a school physical examination. The teacher reminded his parents to take their children to the hospital for a checkup. When Ms. Jin, who was holding the test results, asked her son if he could see the blackboard clearly, she was told that he could. So she didn't take it seriously and wondered if the test was inaccurate.

In recent weeks, Fanfan always likes to squint when looking at things. Last weekend, Ms. Jin took him to the hospital for a checkup and found that Fanfan already had 100 degrees of myopia.

"Why is he myopic? Can't he see the blackboard clearly?" Ms. Jin was very puzzled. Dai Hongbin, member of the Standing Committee of the Ophthalmology Branch of the Hubei Provincial Chinese Medicine Association and chief physician of strabismus and amblyopia and pediatric ophthalmology at the Aier Eye Hospital affiliated to Wuhan University, said that many parents are "stubborn" when facing their children's myopia problems. The standard for judging whether their children's vision is normal is whether they can see the blackboard clearly. As long as they can see clearly, there is no problem. In fact, it is not the case. If the child encounters slightly smaller words on the blackboard or electronic whiteboard, he will squint and look hard. This is him using the adjustment function of his eyes. Teenagers have strong eye adjustment ability, and they may see clearly as soon as they try hard. But continuous squinting will keep the ciliary muscles in a state of fatigue, thereby aggravating the development of myopia.

"If I had known this, I would have brought him for a check-up earlier," Ms. Jin said in annoyance after hearing the doctor's explanation.

Unhealthy eye use and deterioration of the eye environment are important factors affecting the formation of myopia. Inadequate sleep time, excessive homework time, continuous close-up eye use time, and unscientific use of electronic products are common among adolescents. The time and space for students to stay outdoors have obviously decreased. Coupled with the proliferation of electronic products, students stare at electronic screens for a long time, and their eyes are always in a state of ciliary muscle adjustment fatigue, all of which increase the risk of myopia among adolescents.

Dai Hongbin reminded that "early monitoring, early warning, and early intervention" are the keys to solving the myopia problem. Parents need to establish a correct awareness of myopia prevention and control. In addition to taking their children for vision screening regularly, they must also ensure that their children have sufficient outdoor activities every day. Once they find that their children have problems such as decreased vision, squinting, blinking, rubbing their eyes, and liking to watch TV at close range, they should go to a regular ophthalmic medical institution for a comprehensive examination in time, make a clear diagnosis, and formulate targeted myopia prevention and control plans.
