China News Service, August 27th (Reporter Chen Jing) Regarding the child wearing glasses, many parents always feel that once the child wears glasses, the degree will only get deeper and deeper.

Zhang He, director of the Optometry Center of Shanghai Aier Eye Hospital, said bluntly in an interview on the 27th: "If myopia occurs without wearing glasses, a blurred image will be formed on the retina, causing instability of accommodation. As a result, the eye axis will continue to grow and the degree of myopia will be increased. Deepen. This will also bring additional burden to the eyes, cause visual fatigue, and affect the child's study and life."

  Xiaoxin (a pseudonym), who was 10 years old during the winter vacation this year, was diagnosed with 100-degree myopia, but Xiaoxin's parents did not take it seriously and did not wear glasses for him.

School was about to start, and when he checked again, Xiaoxin's degree soared by 200 degrees.

  Zhang He pointed out that myopia is not a self-limiting disease, unlike a cold, as long as the time is long enough, it will always be better.

"For adolescents, even mild myopia needs to follow the doctor's advice to wear glasses reasonably." The expert emphasized that once a child is confirmed as true myopia, he must go to a professional hospital to get glasses.

  Zhang He told reporters that for the first time adolescents and children have visual loss, they should undergo medical optometry first to determine whether they are true myopia or pseudomyopia.

According to reports, pseudomyopia is more common in adolescents, due to excessive eye use, continuous contraction of the ciliary muscles causes blurred vision.

Zhang He said that this situation can be alleviated by relaxing and adjusting from a distance, and vision can return to normal.

However, if you are diagnosed with true myopia, you must use glasses and other optical methods to correct it to delay the progression of myopia.

  During the interview, the reporter learned that, in fact, there are many misunderstandings about myopia in the market, such as: “If you can see clearly, it’s okay”, “If you are nearsighted, wear glasses or have surgery”, “If your vision is normal, you won’t have myopia”. Wait.

  Zhang He explained that if a child encounters a smaller word on a blackboard or an electronic whiteboard, he will squint and look hard, indicating that he is already using the adjustment function of his eyes.

However, continuous squinting will keep the ciliary muscles in a state of fatigue, thereby exacerbating the development of myopia.

  Excessive myopia is likely to bring some pathological changes, such as retinal degeneration, retinal tears, retinal detachment, and even blindness.

Zhang He bluntly said that this is not something that can be solved by wearing glasses.

Myopia surgery can only correct the degree, and cannot change the length of the eye axis and the internal structure of the eyeball.

He emphasized that parents must not "underestimate" myopia, especially not allowing their children to develop into high myopia.

  The expert told reporters that routine vision testing cannot be used as a standard for diagnosing myopia.

If the result of the vision test shows low vision, the child may have myopia, farsightedness, astigmatism, or poor vision development.

True myopia detection requires professional ciliary muscle palsy optometry to determine.

The results of routine vision tests are abnormal, and parents should take their children to the hospital to see what causes it.

  Zhang He suggested that preschool children should be tested every three months or six months, and elementary and middle school students should be tested for diopter and eye axis data every six months to a year.

Those with large diopter changes need to scientifically prevent and control myopia based on the advice of an optometrist or doctor.
