Abstract: if children have no problems with their eyes, they are generally not prone to myopia during this period. However, due to abnormal eye development or genetic factors of myopia, children’s vision can be affected during this period. Therefore, early visual examination is the best way to find children’s myopia in time., The types of myopia are as follows: 1. Children who sleep less are prone to myopia. In the accelerated period of children’s growth and development, especially when they are 7-9 years old and 12-14 years old, if the children’s sleep time is reduced or artificially deprived of sleep time (excessive homework burden), myopia will occur in some children., 2。 Children with low birth weight are prone to myopia. Children who weigh less than 2500 grams at birth are prone to myopia before puberty. This is mainly due to the congenital dysplasia of low birth weight children and the long development of ocular axis caused by adverse factors., 3。 Premature children are prone to myopia. Myopia often occurs in children born 2 weeks or more prematurely. The mechanism of myopia in these children is the same as that in low birth weight children., 4。 Parents are myopic, and their children are prone to myopia. The genetic degree of myopia increases with the deepening of degree. Generally speaking, myopia below 300 degrees has little to do with heredity; Myopia of 300-600 degrees is closely related to heredity; Almost all myopia above 600 degrees is related to heredity., Under normal circumstances, when the baby is 3 months old, the visual acuity is 0. 012-0。 02, visual acuity was 0 at 6 months. 05, so the hyperopia ability of children under the age of 1 is relatively poor, which is 0 at the age of 1. 2. After that, the visual acuity will increase by about 0 for each l-year-old. 2. The visual acuity reaches normal at the age of 5. 1. The eyeballs of children aged 0 and 12 are fully mature., If the child’s eyes are OK, myopia is generally not easy to occur during this period. However, due to abnormal eye development or genetic factors of myopia, children’s vision can be affected during this period. Therefore, early visual examination is the best way to find children’s myopia in time.,
belongs to the type prone to myopia as follows:
1. Children who sleep less are prone to myopia. In the accelerated period of children’s growth and development, especially when they are 7-9 years old and 12-14 years old, if the children’s sleep time is reduced or artificially deprived of sleep time (excessive homework burden), myopia will occur in some children.
2。 Children with low birth weight are prone to myopia. Children who weigh less than 2500 grams at birth are prone to myopia before puberty. This is mainly due to the congenital dysplasia of low birth weight children and the long development of ocular axis caused by adverse factors.
3。 Premature children are prone to myopia. Myopia often occurs in children born 2 weeks or more prematurely. The mechanism of myopia in these children is the same as that in low birth weight children.
4。 Parents are myopic, and their children are prone to myopia. The genetic degree of myopia increases with the deepening of degree. Generally speaking, myopia below 300 degrees has little to do with heredity; Myopia of 300-600 degrees is closely related to heredity; Myopia above 600 degrees is almost related to heredity.
under normal circumstances, when the baby is 3 months old, the visual acuity is 0. 012-0。 02, visual acuity was 0 at 6 months. 05, so the hyperopia ability of children under the age of 1 is relatively poor, which is 0 at the age of 1. 2. After that, the visual acuity will increase by about 0 for each l-year-old. 2. The visual acuity reaches normal at the age of 5. 1. The eyeballs of children aged 0 and 12 are fully mature.
if the child’s eyes are OK, myopia is generally not easy to occur during this period. However, due to abnormal eye development or genetic factors of myopia, children’s vision can be affected during this period. Therefore, checking vision as soon as possible is the best way to find children’s myopia in time.
and
to check children’s eyesight, we should be patient and kind, give more praise and encouragement, and strive for children’s cooperation, so that the results can be accurate. In addition, parents should also carefully observe their children’s every move in their daily life. If they find that their children are slower, clumsy, inactive, unwilling to play games, or love to tilt their heads, frown and squint when watching things, sit close to TV, often rub their eyes with their hands, and fail to concentrate and see the blackboard clearly after school If the academic performance drops or the reading distance is very close, and the symptoms of visual fatigue such as eye soreness, pain and dizziness occur in less than half an hour, the child should be taken to the hospital for examination and mydriasis optometry if necessary.
parents must carefully observe their children, especially children with genetic tendency of myopia, and cooperate with kindergartens and schools to check their eyesight regularly, so as to find their children’s myopia early.
and
finally emphasize that the most effective and convenient way to find myopia is to check your eyesight regularly, usually once every 3-6 months, but you must go through optometry to diagnose myopia.
count which children are more likely to suffer from myopia. Timely treatment is the key.
eye exercises can prevent myopia.
in view of the rising trend of juvenile myopia in recent years, relevant experts remind that prevention is the most important way to treat myopia. The most important way is to wear appropriate glasses and do eye exercises well, Don’t superstitious about the various myopia prevention devices on the market.
and
experts believe that eye exercises are still an important means to prevent myopia. Finding the correct acupoints and careful operation are the key. Experts stressed that the two links of “closing your eyes and meditating” and “overlooking” in adolescent eye exercises can give your eyes a full rest and improve your tension. Therefore, you should pay special attention when doing it.
it is understood that the promotion of eye exercises in primary and secondary schools in China began in the 1960s, and Beijing was the first city to implement eye exercises. Over the past 40 years, eye exercises have been gradually improved and simplified, and have become an important measure to prevent myopia in primary and secondary schools. In recent years, with the increasing burden on students and the popularity of computers, televisions and game consoles, teenagers’ eye use has increased, but eye exercises have not received corresponding attention. Although more than 70% of students said they insisted on doing eye exercises every day, the survey showed that many students could not correctly find acupoints. Experts suggest that school doctors and teachers should play the role of supervision and guidance to help students learn correct eye careExercise posture.
it’s best to wear glasses to correct myopia.
experts say that because children are young, they can’t accurately express their feelings, and some eye diseases have no special symptoms. Therefore, parents should observe carefully, and it’s best to take their children for regular examination to prevent trouble.
and
if the child is found to squint, get close, be afraid of light, or tilt his head or face, it is necessary for parents to take the child to see a doctor, so as to find amblyopia, strabismus, ametropia and other eye diseases as soon as possible. Usually parents should pay attention not to let children often rub their eyes with their hands to prevent infection with trachoma; Cultivate children’s good hygiene habits and equip them with special towels and washing utensils.
and
experts suggest that if
and
have a family history of eye diseases, parents should take their children to be examined by an ophthalmologist before one year old. For children aged 3-6, it is necessary to go to the hospital ophthalmology for a comprehensive examination regardless of their eyesight. 8-16 years old is the peak of myopia in children and adolescents. Therefore, parents should urge their children to develop good eye habits: don’t look at things closely for a long time, don’t read books in too strong or too dark light or exercise, and adhere to eye exercises.
in addition, the earlier the age of myopia, the better the effect of treatment. The best way to correct myopia is to wear glasses. Parents must not trust some instruments and drugs. Optometry and glasses should go to a regular hospital. There are often glasses shops in the street that claim that “scientific glasses are desirable immediately”, and most of them ignore the step of mydriatic optometry, which is exactly an indispensable detection means for children and adolescents before glasses matching, because the younger the child is, the stronger the elasticity of the crystal is, the greater the adjustment force is. For children with ametropia, if they do not mydriatic optometry, some adjustment will be hidden, Thus affecting the accuracy of optometry.
