Children's "eyes" make life colorful, no "points deducted" for myopia

Children and adolescents are the key groups for eye protection

"Prevent myopia from childhood"

"Bathe in the sun and stay away from myopia"

"Keep fit to prevent myopia, a strong body will keep your eyes bright"

Studies have shown that myopia in children and adolescents is mainly simple myopia, which is influenced by both genetic and environmental factors , among which environmental factors play a more important role , such as the amount of outdoor activities, close work, reading and writing habits, lighting, eating habits, etc.

Environmental factors are controllable, while genetic factors, including parental myopia, family clustering and certain genes, currently have no way to intervene. Therefore, we should pay more attention to environmental factors that affect myopia and prevent children and adolescents from being affected by adverse environmental factors.

Currently, myopia is incurable and once it occurs, it is irreversible.

0-6 years old is the critical period for children's health protection and myopia prevention and control. The plastic period of visual development is 0-3 years old, and the sensitive period is 3-10 years old. Therefore, myopia prevention and control must be "started early and started young."

So, how should children and adolescents of different ages prevent and control myopia? Experts suggest: Active measures should be taken to prevent myopia when children are not yet myopic.

Let’s take a look together!

Children aged 0-6

0-6 years old is the stage when the eye develops the fastest, so we should pay attention to preventing the occurrence of myopia.

Medical experts point out that the earlier myopia occurs and the faster it develops, the higher the probability of developing into high myopia .

Therefore, to prevent myopia, the threshold should be moved forward. Children should do the following in their daily lives:

Children aged 0-3 years old should not be exposed to electronic screens, including televisions, mobile phones, iPads, etc.

Children aged 4-6 should use electronic products occasionally, but not for more than 15 minutes at a time.

It is not appropriate to carry out primary school education content such as writing and reading text books for children aged 0-3 years old ;

Kindergarten children aged 4-6 should develop correct reading and writing postures, read for 20 minutes continuously, and relax their eyes through one or more methods such as gazing into the distance/light activities/outdoor activities/doing eye exercises , etc.

It is recommended that kindergarten children spend 3 hours outdoors every day , and more childcare can be done outdoors.

Avoid refined sugars and eat a balanced diet.

Ensure adequate sleep time, kindergarten children should get more than 11 hours a day.

Turn off the lights when you go to bed at night, keep the sleeping environment as dark as possible, and avoid sleeping with a night light on

Conduct vision and refractive examinations regularly and establish an eye refractive development file.

Pay close attention to changes in hyperopia reserves to prevent them from being depleted prematurely.

Primary and secondary school students

1 People without myopia

Ensure adequate time for outdoor activities

Many scientific studies have shown that outdoor activities can stimulate the retina to release dopamine, which can inhibit the growth of the eye axis and prevent the occurrence of myopia. 2 hours a day and 14 hours a week of daytime outdoor activities can effectively prevent the occurrence and development of myopia, and is currently the most economical and effective measure to prevent myopia.

Primary and secondary school students are encouraged to walk out of the classroom during the 10-minute break, do some exercise outdoors, or look into the distance to relax their tense eyes. It is recommended that children and adolescents walk to school all or in stages, and that lower grade students be accompanied by their parents.

Go outdoors with your children on weekends and holidays and go to nature. One hour of physical exercise every day can be included in the 2 hours of daytime outdoor activities. There is no limit to the form of outdoor activities. Biking, playing table tennis, playing badminton, playing basketball, flying kites, playing football, running, looking into the distance, and walking are all good outdoor activities.

It needs to be emphasized that exercise outdoors in the "sunlight" can better prevent myopia.

Develop correct reading and writing posture

Keep a correct reading and writing posture, and keep the reading and writing positions within the limits of “one foot, one fist, one inch”.

Keep your eyes one foot (about 33 cm) away from the book, and your body a fist away from the desk. When holding a pen, your fingers and the tip of the pen should be one inch (about 3.3 cm) apart, and the hand holding the pen and the tip of the pen touching the paper should be kept at 40-45 degrees.

Holding the pen correctly is a prerequisite for correct sitting posture.

Develop good eye habits

Avoid using your eyes at close range for long periods of time, and take breaks after continuous close use.

Avoid reading or using electronic products while walking, riding in a car, lying in bed, or in direct sunlight or dim light.

Lower grade primary school students read and write for 40 minutes, and relax their eyes through one or more methods such as gazing into the distance/light activities/outdoor activities/doing eye exercises, etc.

Use your eyes in a good visual environment to reduce eye burden

When reading or writing, let natural light come in from the side opposite to the writing hand to avoid shadows blocking your vision; avoid direct sunlight.

Desk lamps with national compulsory product certification (i.e. CCC certification) should be used. When young students study at night, they should also turn on the ceiling lights in the room when using desk lamps to ensure that the light intensity on the desk is greater than 300 lux.

Limit the time you spend using electronic products

The LCD screens of electronic products such as computers, mobile phones, and tablets emit short-wavelength blue light. Long-term use can cause red eyes, dry eyes, sore eyes, decreased vision, and visual fatigue. Therefore, in daily life, the time and intensity of using electronic products should be reduced.

Do not play or play less with mobile phones, computers or game consoles during entertainment time. For non-learning purposes, the play time should not exceed 15 minutes/time or 1 hour/day.

For electronic products, projectors and large-screen TVs are preferred. For the same screen size, choose electronic products with high screen resolution.

The viewing distance for TV should not be less than 4 times the diagonal distance of the screen, the horizontal viewing distance for computer should not be less than 50cm, and the viewing distance for mobile phone should not be less than 40cm.

Do eye exercises carefully

Standardized eye exercises can slow down the growth of primary school students' refractive power and axial length, improve visual fatigue and increase sensitivity, and help delay the occurrence and development of myopia.

Build a good lifestyle

Getting enough sleep every day is helpful to relieve visual fatigue. Primary school students should sleep more than 10 hours a day, junior high school students should sleep more than 9 hours a day, and high school students should sleep more than 8 hours a day.

Proper diet and balanced nutrition

A high-sugar and high-starch diet increases the risk of myopia. Therefore, we should control the intake of sweets and fried foods, drink less carbonated drinks, and supplement with appropriate calcium, phosphorus and vitamins.

Regular check-ups and establishment of refractive development records

It is recommended to have a refractive examination for children every six months to a year to achieve early detection, early diagnosis and early intervention.

Dynamically monitor changes in hyperopia reserve, especially for students in the lower grades of elementary school, to avoid premature depletion of hyperopia reserve and development of myopia.

Children and adolescents should pay active attention to their own vision. If they feel any vision abnormalities or other eye discomforts, they should inform their parents and teachers in time and go to a professional medical institution for examination in time.

In addition, schools and parents should provide children and adolescents with desks and chairs that meet height requirements, and make personalized adjustments to the height of desks and chairs once every semester based on the height and sitting height of the students. Schools with conditions should equip each class with a desk and chair adjustment ruler to regularly measure the height range of students and adjust desks and chairs in a timely manner.

Whether the tables and chairs are suitable can be judged and adjusted as follows: when children and adolescents sit on chairs, their thighs should be perpendicular to their calves, their upper arms should hang down with their backs straight, and their elbows should be 3cm-4cm lower than the table top.

2 People who are already nearsighted

For adolescent students who already have myopia, it is necessary to correct myopia scientifically, while at the same time preventing and controlling the severity of myopia and its complications.

It is particularly important to emphasize that children whose parents are highly myopic or carry genes that cause high myopia should pay more attention to reducing exposure to dangerous environmental factors for myopia.

In conclusion

To prevent and control myopia , we must not only actively participate in myopia screening

If myopia is detected, it must be corrected scientifically

Parents and schools should pay more attention to preventing high myopia

Also be wary of false propaganda such as myopia can be cured

May every child have bright eyes and a bright future!
