Does the child’s hyperopia reserve run out of myopia?

Abstract: in addition to eye fatigue, dry eye and other problems, too much playing with mobile phones and tablets is also easy to make children myopia early. “When these bad eye habits cause the child’s eye axis to develop too fast, it will begin to consume the child’s’ hyperopia reserve ‘. Once the hyperopia reserve is consumed in advance, myopia will appear.”, Since we have smart phones, tablets and other entertainment and communication devices, children’s eye health has become worse and worse. It makes children with poor self-control indulge in it. There are also more and more children with dry eye and myopia at a young age. Every child has a reserve of hyperopia. If it is consumed early, he will start myopia too early. It is suggested to establish refraction from the age of four or five, find the changes of children’s vision as soon as possible, and prevent myopia as soon as possible., Premature consumption of hyperopia reserves is the reason for myopia. It is not difficult to see around us. Many parents are afraid that their children are not obedient and noisy, or want their children to eat obediently. It is very common to feed their children with cartoons while playing iPad and other tablets and smartphones. According to the doctors of Chengdu youth myopia prevention and control special clinic, children will spend too much time staring at iPad and other tablets and smartphones, and their eyes blink less, which is prone to dry eye and other problems., In addition to eye fatigue, dry eye and other problems, too much playing with mobile phones and tablets is also easy to make children myopia early. “When these bad eye habits cause the child’s eye axis to develop too fast, it will begin to consume the child’s’ hyperopia reserve ‘. Once the hyperopia reserve is consumed in advance, myopia will appear.” Studies at home and abroad have pointed out that the ratio of ocular axis to corneal curvature is >, which is a high-risk factor for the occurrence and development of myopia., “Hyperopia reserve” varies with age, and many people do not understand “hyperopia reserve”. Generally, both eyes of newborns are hyperopia. However, with the growth and development, it gradually tends to be normal until the preschool basically reaches normal. In other words, children under the age of 5 have different standards for normal vision, which is closely related to age., Children aged 4-5 years have a physiological diopter of 200-250 degrees, that is, they have a hyperopia reserve value of 200-250 degrees; 175-200 degrees hyperopia at the age of 6-7; 150 degree hyperopia at the age of 8; 125 degree hyperopia at the age of 9; 10 years old, 100 degrees hyperopia; 11 years old, 75 degrees hyperopia; 12 years old, 50 degrees hyperopia. For example, if a 6-7-year-old child’s hyperopia reserve value is much different from 200 degrees, only 50 degrees, it means that the child is likely to get myopia in primary school.,

There are also more and more children with dry eye and myopia at a young age. Every child has a reserve of hyperopia. If it is consumed early, he will start myopia too early.

“hyperopia reserve” different ages

“hyperopia reserve”, many people do not understand. Generally, both eyes of newborns are hyperopia. However, with the growth and development, it gradually tends to be normal until the preschool basically reaches normal. In other words, children under the age of 5 have different standards for normal vision, which is closely related to age.

children aged 4-5 years have physiological diopter of 200-250 degrees, that is, they have hyperopia reserve value of 200-250 degrees; 175-200 degrees hyperopia at the age of 6-7; 150 degree hyperopia at the age of 8; 125 degree hyperopia at the age of 9; 10 years old, 100 degrees hyperopia; 11 years old, 75 degrees hyperopia; 12 years old, 50 degrees hyperopia. For example, for children aged 6-7, if the hyperopia reserve value is much different from 200 degrees, only 50 degrees, it means that the child is likely to get myopia in primary school.

and the standard visual acuity of adolescents and children is closely related to age and is affected by growth and development factors. Relevant literature also shows that the standard visual acuity of children of different ages in China is: 2 years old, 3 years old, 4 years old, 5 years old and above. The simple formula is: age ×。

for parents, if they only rely on their feelings to understand their children’s vision, or wait until their children are nearsighted to pay attention to their vision, the result is naturally bad!

and

Wu Yunlong of Wu’s eyesight hall suggested that parents should establish refraction for their children after their children learn to read at the age of four or five. They can compare with the standard vision and physiological diopter of that age and track their children’s vision, which is of great significance to every child, especially the children who have just found myopia. Find potential problems in time through filing and provide eye guidance; For children with myopia, in addition to eye guidance, they can also control the progress of myopia through corneal shaping lens until they are finalized at the age of 18.
