1, bad learning habits
When many children read books, they are sitting in a wrong position. They either squat on the table to read a book or sit on the ground. This is one of the main reasons leading to children's myopia. Childhood is an important period for cultivating children's good habits. Many people's bad habits are formed when children's time is not corrected. Once you develop a bad habit from a young age, it will be even harder to change it.
The correct posture should be the feet laid flat on the ground or placed on a solid footstool, must not be suspended, the knee bent 85 degrees to 110 degrees, is the most comfortable state, keeping the back normal physiological curvature "S-type" posture, The curvilinear spine can act like a buffer to better support the weight of the body, and one foot away from the book, the chest punched away from the desk, and the hand is an inch away from the nib.
2. TV in the living room
TV eye injury has become a consensus, but not everyone knows what the real causes of TV myopia are. At present, most TVs use LED backlight. This artificial light source can release 450nm high-energy short-wave blue light. It can penetrate the lens directly to the retina and cause serious damage to the children's eyes that are not yet fully developed. At the 2010 International Light Society Annual Meeting, the world's top optical experts agreed that shortwave blue light can cause irreversible vision damage.
TV is the most essential home appliance in the living room. It has brought a vital entertainment life to the whole family. Therefore, it has become impossible to solve the problem of short-wave blue light. When parents purchase TVs, they must choose products with anti-Blu-ray capabilities. Through market research, it has been found that OLED TVs and cool anti-blue eye-protection TVs have the best anti-blue light effects. OLED TVs do not use LED backlights and will not produce 450nm short-wave blue light, but the price is slightly more expensive. The cool blue anti-blue eye TV adopts optical anti-Blu-ray technology to transfer 450nm harmful short-wave blue light into 460nm harmless long-wave blue light through spectral shifting. It can reduce harmful blue light by more than 80%. It is certified by TÃœV Rheinland even children watch it. It will not hurt eyesight, and the price is not expensive. It is the best choice for ordinary consumers.
3, a mobile phone
The popularity of mobile phones is no need to go into details. Whether they are walking or taking subways, there are not many people who are playing mobile phones. Did you know that mobile phones are also one of the main factors affecting children's vision?
Many parents also come up with mobile phones after they get home from work. They do not know that children also develop the habit of playing mobile phones, but mobile phones, like TV, release short-wave blue light, and the mobile phone screen is closer to the human eye, causing more serious injuries. As the saying goes, the power of the model is endless. To prevent children from playing with mobile phones, parents should not play mobile phones around their children. They must accompany children to read books and play with building blocks in order to bring their children a happy childhood.
4, eye health
If children like to rub their eyes, parents should pay attention. Hand hygiene problems will directly affect eye hygiene. Children like to climb on the ground, and everything wants to play, it is inevitable that the hands covered with dust. Unclean hands often rub their eyes directly, and they will inevitably affect the health of eyesight. Therefore, parents should often clean children's toys and remind them not to rub their eyes.
5, lack of sleep
Many children sleep late at night, not knowing that lack of sleep can also affect children’s eyesight. Even if the eyes do not get enough rest at night, it will affect the blood supply and cell metabolism of the eye, resulting in local sympathetic and parasympathetic dysfunction of the eyes, and it is very easy to cause false myopia.
The US NSF recommends 10- to 10-hour sleep for preschool children aged 3-5 years, and 9- to 11-hour for school-aged children aged 6 to 13 years. Parents can set the time for children to sleep. Every night when they reach this time, they must go to bed to solve the children's "delay before going to bed."
Write last
The eye is one of the most important organs of human beings. 80% of information is acquired through the eyes. Therefore, it is very important to protect the visual health of children from childhood, and the National Vision Health White Paper released by the China Health Development Research Center of Peking University in 2016 It shows that the myopia rate of children (6-15 years old) in China is as high as 50%, and the situation is very serious. In the face of the top 5 killers that harm children's eyesight, every parent should pay high attention.
