An eye chart to monitor changes in your child's vision at any time

I. The incidence of myopia in children in my country ranks first in the world

I saw a group of statistics on the myopia rate of children and adolescents in my country: the proportion of myopia among primary school students aged 7 to 12 is 45.71%, and the proportion of myopia among junior high school students aged 13 to 15 years old is 45.71%. The proportion of high school students aged 16 to 18 is 74.36%, and the proportion of high school students aged 16 to 18 is 83.28%. The proportion of college students aged 19 to 22 is as high as 86.36%. From the above data, it can be seen that the rate of myopia among Chinese students is very high. , then it can be foreseen that in the near future, young people wearing glasses will be everywhere on the street, and there are also media reports that the incidence of myopia in children in my country ranks first in the world, which is shocking!

Second, the three stages from pseudo-myopia to high myopia

From pseudo-myopia to high myopia can generally be divided into three stages: pseudo-myopia, true myopia, and high myopia. Pseudo-myopia: continuous use of the eye at close range, continuous contraction and spasm of the ciliary muscle, unable to relax, increased refractive power of the lens, blurred distance vision and clear near vision. True myopia: The degree of myopia remains unchanged or decreases less than 50 degrees after cycloplegic refraction. High myopia: Myopia can be divided into mild myopia, moderate myopia and high myopia according to the degree. Mild myopia: within 300 degrees Moderate myopia: 300-600 degrees High myopia: 600-900 degrees Super high myopia: High myopia above 900 degrees Do not do strenuous exercise, it is easy to cause retinal detachment, and there is a high chance that it will be inherited Generation, the younger the age at which myopia occurs, the more likely it is to cause high myopia.

Three. The state issued a comprehensive implementation plan for the prevention and control of myopia in children and adolescents

The high myopia rate of children and adolescents in my country has attracted national attention. On August 30, 2018, the Ministry of Education, the National Health Commission and other 8 departments jointly The "Implementation Plan for Comprehensive Prevention and Control of Myopia in Children and Adolescents" was issued, and relevant actions should be taken from families, schools, students, medical institutions and other relevant departments to prevent and control the occurrence and development of myopia in a timely manner. It is proposed that by 2030, the myopia rate of 6-year-old children in my country will be controlled at about 3%, the myopia rate of primary school students will be reduced to less than 38%, the myopia rate of junior high school students will be reduced to less than 60%, and the myopia rate of senior high school students will be reduced to less than 70%. Families play a vital role in the prevention and monitoring of children's vision. This plan clearly stipulates that parents should understand the scientific knowledge of eye protection, help children develop good eye habits, and master children's eye development and vision health. Watch for signs of abnormal vision in your child. If there is any abnormality, it should be paid attention to as soon as possible, and go to the regular hospital for examination to avoid the occurrence of high myopia and amblyopia.

Fourth, how can parents monitor children's vision changes

So how should parents find out whether their children's vision is abnormal? It's very simple, all you need is an eye chart. Parents can buy an eye chart online, post it at home, teach their children to identify the direction of the eye chart, check their eyesight regularly and make records. The visual acuity of different ages is different, and the lower limit of visual acuity for each age is shown in the table below. Due to the individual differences in vision development of each person, the above data can only be used as a reference. If parents find that their child's vision does not reach the lower limit of vision for the corresponding age (lower limit of vision: refers to corrected vision or uncorrected vision of the emmetrope), then there must be a problem of. With the growth of age, vision is gradually improved, if the child's vision does not improve, then there is also a problem, you should go to the eye hospital for examination.
