In recent years, the myopia rate of children and adolescents in our country has been high. According to statistics, in 2020, the overall myopia rate of children and adolescents in China is 52.7%; Among them, 14.3% were 6-year-olds, 35.6% were elementary students, 71.1% were middle school students, and 80.5% were high school students. Among them, the myopia rate of senior high school students in some cities even exceeds 90%. The situation of preventing and controlling myopia among children and adolescents is very serious. The country's myopic population has reached 600 million people, and wearing myopic discount eyeglasses online is still the main choice for most young people with myopia. However, ophthalmologists told reporters that there is a deviation between the degree of myopia worn by a considerable number of children and adolescents and the actual degree of myopia. A primary school student in Henan province actually has only 50 degrees of myopia, but the optician gave him a pair of 200 degrees of myopia glasses.
Not long ago, Henan Eye Hospital received a patient who was less than 10 years old. According to the preliminary understanding of experts, the patient in the optician with a pair of 200 degrees of myopia glasses, there are uncomfortable symptoms of acid swelling.
Shi Menghai, deputy director of the optometry Department of the optometry Center of Henan Provincial Eye Hospital: He had some discomfort after wearing corrective glasses, his eyes were sore, especially when he looked close to fatigue.
Experts through mydriatic optometry found that the patient's myopia is only 50 degrees, and the glasses are 150 degrees off. False myopia does not require glasses at all. His eye discomfort was caused by a serious deviation in the degree of the myopia mirror.
Shi Menghai, deputy director of the optometry Department of the optometry Center of Henan Provincial Eye Hospital: The optician said that the examination of myopia is 200 degrees, we pass the examination, through myodatic optometry, the child's degree may only be dozens of degrees.
Children and adolescents should choose the hospital for their first optometry
According to experts, the adjustment of the adolescent eye is strong, and the purpose of mydilation is to make the eye can not be adjusted when optometry, so the results are more accurate. In particular, teenagers with farsightedness, if they do not carry out mydriatic optometry, the deviation is greater. At present, only hospitals have the qualifications to do mydriatic optometry. Ordinary optical shops can not do this examination, so children and teenagers should choose a hospital for their first optometry.
Shi Menghai, Deputy Director of optometry Department, Optometry Center, Henan Eye Hospital: If the child is found myopia for the first time, must first go to the hospital to do myoptometry, to confirm the child's degree after the prescription, otherwise there may be this degree difference is very large, let the child wear a degree is too high a glasses, and finally lead to the child's degree development too fast, sometimes even say that if you do not come to the hospital to check, but also found this situation.
Experts told reporters that because there is no myodatic optometry, the phenomenon of large deviations in optometry of children and adolescents is common in optometry shops and other out-of-hospital institutions.
Shi Menghai, deputy director of the optometry Department of the optometry Center of Henan Provincial Eye Hospital: The optometry of institutions outside the hospital, we reviewed and found that the degree deviation is relatively large, and the deviation of more than 50 degrees is actually seen every week.
The optometry error of some opticians is more than 500 degrees
The reporter's investigation found that the phenomenon of large deviations in optometry in some optical stores exists to varying degrees throughout the country. In particular, children and adolescents with far-sighted eyes are more likely to have deviations, and some errors even exceed 500 degrees.
Wang Dajiang, director of ophthalmology, Department of Ophthalmology, PLA General Hospital: Some children are far-sighted, myopia may not be very bad, far-sighted extreme cases may be worse than five or six hundred degrees, you from the optician shop with glasses, and then to the hospital myopic optometry, this gap may have five or six hundred degrees, in fact, it is quite amazing.
According to experts, once children and adolescents mistakenly wear myopia glasses with higher degrees, they are often irreversible, and also increase by about 100 degrees per year.
Wang Dajiang, director of ophthalmology, Department of Ophthalmology, PLA General Hospital: At this time, there are great risks to high myopia, including the risk of glaucoma and retinal detachment, and eye diseases will follow.
