Now is the information age, 85% of the information is transmitted to the brain through the eyes. If children are not prevented and treated well, a large number of children will have serious vision fatigue, sore, painful and swollen eyes, or eyes that are outwardly slanted, so there is no way to look at the computer and read books, which is bad. At present, there are many misconceptions in the vision prevention market that fool children about myopia prevention, so be sure to identify them clearly. The “pupil dilatation is harmful to children” is a lie. Some people say that the pupil dilatation is harmful to children’s eyes, you should not go to the pupil dilatation, the pupil is one, the child’s eyes will be broken. Let me tell you, this is a lie. In other words, astigmatism is not harmful to children’s eyes, why? The scientific name for dilated optometry is not called dilated optometry in medical terms, it’s called adjusted paralysis optometry. Therefore, children under 12 years of age must use dilated optometry in order to be tested accurately for myopia. Why is dilated optometry called adjusted paralysis optometry? The Himalayas are more than 8,800 meters high, you can measure from the bottom of the mountain to the mountain is definitely not 8 km, it is evaluated by the sea level. And the adjustment paralysis, equivalent to the sea level, before the energy your degree is farsighted, myopic or astigmatism. Therefore, there is a rule: people under 12 years old must dilate the pupil for optometry, and people with hyperopia must dilate the pupil for optometry, otherwise you are not tested correctly, even the farsighted nearsightedness is not clear, how to prevent and control it? The medicine for pupil dilatation is actually not harmful to the eyes. In some cases, the medicine for dilated pupils is still one of the methods of treatment for myopia, so there is nothing to fear. However, ordering drops is a medical act, and dilated eye examinations must be done under the guidance of a health care provider. A girl was 12 years old and could not read the board clearly. Her mother, a pediatric professor, gave the child glasses for 2 months, and the girl came to me with headache, double vision and two shadows. After the dilated eye exam, the pupil distance was 65mm, but the pediatric professor did not dilate the child’s pupil and found the pupil distance to be 58mm, so the lenses were also made wrong and the child’s eyes were internally oblique. After re-dispensing the lenses, the child was fine. ”It is not scientific to say that myopia below 200 degrees is called pseudomyopia. There is also a saying that myopia below 200 degrees is called pseudomyopia. Pseudomyopia does not require glasses. Wrong, don’t let him fool you. To determine if it is pseudomyopia, you must have a dilated eye exam to determine. It is called pseudomyopia only when there is no myopia in the dilated eye test. Of course, there is a certain error in optometry, optometry and ophthalmology, plus or minus 50 degrees in the error range, that is, 50 degrees of myopia is not called myopia, 50 degrees of hyperopia is not called hyperopia. Therefore, you should not be fooled by some treatment institutions and opticians, whether to wear glasses or not must be determined by the doctor after consultation. Pseudomyopia is very rare, our statistics are only 2.4%, so don’t let him fool you. Beware of looking at two different vision tables before and after treatment. When we do optometry and vision check, we must put the vision table at a distance of 5 meters under parallel light. I am now the director of the Shanghai Ophthalmology Quality Control Center. The quality of ophthalmology in hundreds of hospitals in Shanghai is controlled by our office, and this is the 11th year. In the previous years, we inspected the vision tables and optometry offices of hospitals every year. When we checked, we found that some hospitals had two vision tables before treatment and after treatment. Before treatment, take a leather ruler and measure the distance between the sitting position and the vision table is 5.5 meters, after treatment is 4.5 meters. The distance must be 5 meters to be parallel to the light. The daily practice of “eye contact” can prevent myopia hand in front of the eyes, extend the index finger, move the hand back and forth, eyes on the moving finger to see, do 50 times a day in the morning, 50 times in the afternoon, just like the practice of eye contact. An ophthalmologist in the Soviet Union did experiments and selected 50,000 5-year-old children in Moscow to do this action every day. after 10 years, he found that the myopia rate of these teenagers was only one-tenth of that of normal children. To protect the child’s eyesight, the mother should pay attention to more exercise and maternity exercises from the perinatal period to promote fetal movement and eye development. To prevent myopia in teenagers, we should start from daily life, strengthen physical exercise, avoid uncontrolled TV, computer and game watching, appropriate lighting at home, and regular vision checkups, etc. Once the diagnosis of true myopia is confirmed, it is impossible to cure it, only glasses or refractive surgery can be done. The key to preventing myopia in adolescents is prevention. When parents notice their children squinting, sticking their heads out, or looking at things with a crooked head, the child is probably already myopic. It is important to have a correct pencil grip. If the thumb is placed on the index finger when holding a pen, it will block the line of sight and the head will involuntarily be tilted, making it easy to be nearsighted. The correct posture is with the thumb next to the middle finger.
