Every child has a reserve of hyperopia and is short-sighted when used up

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 start to consume the child’s’ hyperopia reserve ‘. Once the hyperopia reserve is consumed in advance, myopia will appear.

premature consumption of” hyperopia reserve “is the reason for the child’s myopia.

are not difficult to see around us. Many parents are afraid that their children will not obey and make trouble, Or hope that children eat obediently, lure children with tablets such as iPad and smart phones, and feed children while playing cartoons is very common. Too much contact with iPad and other tablet computers and smart phones, children will spend too much time staring, blink less, prone to dry eye and other problems. “We met a 3-year-old child with dry eye in the clinic because we usually watch too much and too long on tablets and smartphones.” It’s not difficult to see around us that many parents are afraid that their children are disobedient and noisy, or want their children to eat obediently. It’s common to lure their children with tablets such as iPads and smartphones, and feed their children while playing cartoons. An ophthalmic outpatient expert said: too much contact with iPad and other tablets and smartphones, children will spend too much time staring, less blinking, prone to dry eye and other problems. “We met a 3-year-old child with dry eye in the clinic because we usually watch too much and too long on tablets and smartphones.”

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 > 3.0 is a high-risk factor for the occurrence and development of myopia.

and “hyperopia reserve” vary by age. Many people do not understand the “hyperopia reserve” called by

and

experts. 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, the standard of normal vision of children under the age of 5 is different from that of adults, and this standard is closely related to age.

she pointed out that 4-5-year-old children 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. 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.

and the standard visual acuity of adolescents and children is closely related to age and is affected by growth and development factors. The literature shows that the standard visual acuity of children of different ages in China is 0.5-0.6 at the age of 2, 0.9 at the age of 3, 0.9-1.0 at the age of 4, and 1.0 and above at the age of 5 and above. The simple formula is: age × 0.2。

and

suggest that refractive files should be established from the age of four or five.

and

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 in ophthalmic clinics.

every child has a reserve of hyperopia. If it is consumed early, it will start myopia too early. It is suggested to establish refractive files 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.

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

moreover, after children learn to read at the age of four or five, they can build refractive files for their children, which can be compared with the standard visual acuity and physiological diopter of that age, and track their visual acuity, which is of great significance to every child, especially those who have just found myopia. Find potential problems in time through filing and provide eye guidance; For children with myopia, they can do vision training through 1.5 vision recovery instrument to control the degree from increasing, and gradually improve their naked vision on the basis of adhering to the use as required.

if you want to have good eyesight, you should not choose

and

for Piano and other musical instruments to develop your interests. Is it better to learn piano, violin, wind instruments and other musical instruments, or to participate in outdoor sports such as football, cycling and tennis? Ophthalmologists said that if you want to have good eyesight, you’d better not learn piano, violin, wind instruments and other instruments, which will only make myopia come earlier and develop faster.

“learning piano and other musical instruments is an important factor in the development of myopia in many children. It can deepen more than 200 degrees a year!” Experts pointed out that learning musical instruments should focus on the music score and Practice for hours. Reading music scores while playing, playing and playing the piano is just like reading in sports. It is easy to cause myopia after a long time.

and outdoor activities such as tennis, kite flying, cycling and mountaineering can not only contact more sunlight and promote the secretion of dopamine, dopamine can block the growth of ocular axis and reduce the risk of rapid development of ocular axis; In addition, ultraviolet can increase the synthesis of vitamin D in the body and harden the sclera, which is also helpful to slow down the growth of ocular axis.
