Parenting knowledge of protecting eyes: how to protect children's eyes 1, sufficient light.
The light should be sufficient and comfortable (the light is too weak to see the font clearly, and the more you look, the more nearsighted you are).
2. Reflexive avoidance.
The desk should be equipped with edge light in order to reduce reflection and damage to eyes.
3. Don't read for too long.
No matter doing homework or watching TV, the time should not be too long. It is best to have a rest every hour or so.
The above is a detailed introduction on how to protect children's eyes. Parents should pay attention to it. For children's eye protection, it should be carried out for a long time, so that the baby can develop good living habits and let him gradually know how to protect his eyes and what he should do.
Parenting knowledge to protect your eyes: six tricks to teach you to protect your child's vision 1. Parents should check their children's eyesight regularly, so as to find children with poor eyesight at an early stage, find out the reasons and take appropriate preventive measures. Students must wear corrective glasses if their eyesight is impaired and their study is affected. The prescription of glasses they wear must be decided by a special ophthalmologist, and they can't borrow other people's glasses. People with high myopia should avoid all kinds of strenuous exercise to prevent serious consequences such as retinal detachment.
2. Guide children to cultivate good eye habits from an early age and consciously pay attention to eye hygiene. When reading and writing, the posture should be correct, that is, the head should be straight and not skewed, and the eyes should keep a certain distance from the desktop and books. The general distance should be greater than 30 ~ 35cm and not less than 25cm. When reading, make the handwriting at right angles to the line of sight, so that the strokes of each word extend to the eyes to form the largest angle of view, and the images formed by the words on the retina are the clearest. So it's best to raise the top of the book properly or hold it by hand, so that the book and the desktop form a 30? ~40? Angle, then as long as the head leans forward slightly, you can make the words on the book look the clearest.
Don't read when walking or riding a bike, don't write with your head tilted, and read while lying down. Because it is not easy to keep a proper distance between eyes and books, it is necessary to constantly change the distance, so that eyes are easy to get tired and reading while lying down is easy to form strabismus.
Children should not watch TV for too long and keep a certain distance. Generally, you should rest for 5 ~ 10 minutes after watching TV for half an hour. The eyes and TV screen should be slightly lower than the children's eyes. The distance should generally be 5 ~ 7 times the diagonal of the screen. Keep a certain illumination indoors to avoid glare. After watching TV, you can do some relaxing full-body activities or eye exercises. Watching TV at the same time should not be too long.
3. Children's learning environment should ensure proper lighting conditions. No matter at school or at home, you should study in sufficient bright light, and don't read in dim light and moonlight; Don't read at dusk, dawn or when the sky is dark.
Reading under direct sunlight or dazzling electric light will produce strong glare, which will hurt your eyes and affect your eyesight. Read books by candlelight and kerosene lamps without covers, because their flickering light is the most harmful to the eyes, causing headaches and dizziness. So don't read in the light above.
When reading a book, the light source should come from the upper left, which can avoid the shadow caused by harsh light and light in other directions from hindering reading and writing. The position of the light source can be adjusted according to the brightness, for example, a light bulb with a large degree can be higher and a light bulb with a small degree can be lower.
Children should have suitable desks and chairs for reading and writing. Indoor air circulation and suitable temperature should be about 65438 06 ~ 65438 08℃. Generally, tables and chairs should be suitable for children's height and sitting height, so as to avoid inappropriate tables and chairs from affecting children's reading and writing posture. In addition, students' seats in class should be changed regularly, and the front desk should keep a distance of more than 2 meters from the blackboard to avoid unnecessary visual impact.
5. Prevent eye fatigue. When studying or working for myopia for a long time, you should rest or play properly, or change to some studies that don't make your eyes nervous, such as singing and dancing. When reading or writing continuously for a long time, you should rest your eyes for a few minutes every hour. In the few minutes of rest, the teacher must let the students go outside to exercise, correct the muscle fatigue caused by fixed sitting posture and relax their eye adjustment.
6. Strengthen the whole body exercise and pay attention to proper nutrition. Encourage children to participate in outdoor activities and games and get in touch with the sun. Live regularly, go to bed early and get up early, ensure adequate sleep and proper rest, and do eye exercises during rest to improve physical fitness.
Take proper nutrition and avoid partial eclipse and overeating. Eat more foods containing vitamins A, B, C, D and calcium, such as animal liver, beans, milk, eggs, fish and shrimp, persimmons, carrots, vegetables and coarse grains.
How do pupils protect their eyes? How are they nearsighted? How to deepen the degree of wearing glasses? How should primary and secondary school students protect their eyesight? Here are some ways to prevent myopia.
First, the light should be sufficient to avoid reflection.
Comfortable light can get good visual information, and too strong or too dark light will bring bad effects to the eyes. Therefore, the desk where teenagers usually read books should have a side light device, with the purpose of reducing reflection and eye damage.
Second, continuous reading time should not be too long.
Teenagers read, write, watch TV and use the computer for hours without rest, and some students even go to bed late at night, which not only affects their health and makes their eyes overburdened, but also easily causes accommodative (or functional) myopia, that is, pseudomyopia. Moreover, the extraocular muscles will exert pressure on the scleral tissue of the eye wall, which will increase the intraocular pressure and make the intraocular tissue congested. Therefore, it is advisable for students to have a rest every 50 minutes when studying.
Third, the sitting posture should be correct and the distance should be moderate.
Don't hunch over, or read at your desk, let alone lie on the bed and read sideways. Keep the distance between your eyes and the book at 30? 35 cm, the distance between the body and the desk is about 10 cm, and the included angle between the book and the desk should be kept at 30? 45 degrees. If you put the book horizontally on the desktop, lean your head forward slightly when reading, which will easily move the book closer to your eyes and increase the burden on your eyes. 3 times, thus causing fatigue of the neck muscles and the back of the neck. Long-term involuntary leaning forward will lead to decreased vision.
Fourth, watch less TV and use less computers.
Try to reduce contact with TV, computers, game machines and other electrical equipment that radiate to human eyes, because X-rays radiated by kinescope will consume rhodopsin in retina in large quantities, which can obviously reduce vision.
It is best to use LCD as a computer to reduce the harm of electromagnetic waves to the eyes. Students who often play video games are more likely to damage their vision, while students with low vision who play video games since childhood can't even correct their vision with glasses because of the impaired function of retina and macula.
Fifth, get enough sleep and pay attention to eye hygiene.
Work and rest should be regular and get enough sleep. Lack of sleep can lead to conjunctival congestion, increased secretion, photophobia and tears, eye pain and other conjunctival and corneal inflammation. We should try our best to avoid eye damage caused by sandstorms, smog, ultraviolet rays, infrared rays, chemicals and medical supplies. Personal hygiene should be kept clean, towels, washbasins, handkerchiefs and other personal items should be used by special personnel, and try not to use other people's items to avoid cross-infection, eye diseases and decreased vision.
6. Don't read while driving or walking.
Some teenagers like reading while walking, or reading in a walking carriage, which is very bad for their eyes, because the carriage is shaking, their bodies are shaking, the distance between their eyes and books can not be fixed, and poor lighting conditions increase the burden on their eyes, which often leads to myopia.
Seven, do more eye exercises and do more outdoor sports.
Doing eye exercises is a concrete manifestation of attaching importance to eye health care in primary and secondary schools in China. By massaging eye acupoints and muscles, nerve endings are stimulated, blood circulation around eyes is increased, and eye metabolism is adjusted, so as to eliminate fatigue, enhance vision and prevent myopia. In addition, more exposure to natural scenery such as green mountains and green waters is also beneficial to the health of the eyes.
Eight, pay attention to the diet structure, nutrient intake should be balanced.
Balanced nutrient intake, partial eclipse or excessive intake of sugar and protein lead to the lack of trace elements such as zinc, calcium and chromium. , are not conducive to vision health. The prevention method is to eat more vegetables, fruits, liver, fish and other foods.
