Every year during the summer vacation, parents who have time like to take their children out on a trip. First, to be able to feel the different humanities and beauty with children, and help children expand their horizons; Second, it can also accompany children more and promote parent-child feelings.
Although tourism is a good form of parent-child communication, this year's summer vacation has begun, and the sudden epidemic situation in various places and the extremely serious high temperature and extreme weather this year have made many parents cancel the original travel plans. In this case, the children's time at home has increased dramatically.
In the state of home, parents can still create many benign parent-child interaction scenes. For example, watch and discuss high-quality film and television animation works with children, help children establish a correct world view and outlook on life, and exercise children's expression ability; For example, accompanying the office while the child is taking online classes and learning, answering questions for the child in a timely manner, and setting an example of concentration for the child; Another example is to do simple home aerobic exercise with children to prevent the potential harm to the body from sitting at home for a long time. However, it should be noted that these scenes are often accompanied by children watching electronic screens for a long time, which requires parents to pay special attention.
Long-term close-up and the optical radiation of the electronic screen itself have great visual hazards to children and adolescents who are in the development period. Once myopia occurs, it will be a lifelong irreversible damage, so parents and even all sectors of society are very concerned about the prevention and control of myopia in children. It is obviously impractical to completely eliminate children's exposure to electronic products, and if you can help children prevent them, you can also avoid the damage of electronic screens to children's vision to the greatest extent.
So, what can parents do to make their children use electronic products rationally without harming their eyesight?
Last week, the authoritative media in the field of health - People's Daily Health Client and Health Times, held the 14th Healthy China Forum "Eye Health" sub-forum, a number of experts around this issue, from the myopia prevention and control policy, scientific eyes, reasonable choice of electronic display products and other angles expressed their views, for children and adolescents myopia prevention and control put forward practical suggestions.
1. Parents should lead by example
Parents need to lead by example by demonstrating the "right way to open" electronics for their children. When watching TV and computer or playing with mobile phones, sit upright, keep your distance, turn off the screen every thirty minutes, and rest your eyes by closing your eyes or looking far away. Set an example for your child to learn from.
2. Inform children of the harm caused by excessive use of electronic products
Excessive use of electronic products can inevitably cause damage to vision. For children and adolescents, it is difficult to intuitively appreciate the inconvenience caused by "myopia" to their future lives and even their lives. Parents should master more relevant knowledge, clearly and clearly inform children of long-term use of electronic products and myopia if it occurs, which will cause damage to the eyes, so that children can develop a good habit of self-restraint from self-awareness.
3. Choose a laser TV with better eye protection effect
At the forum, many experts mentioned and recognized the eye protection effect of laser TV. Dr. Zhao Xiaoying of the China Electronics Technology Standardization Institute pointed out that the blue light band of the laser TV is 459nm-469nm based on the authoritative test results, which avoids harmful short-wave blue light, and the safety level is RG0 (eliminating blue light hazards). The avoidance of harmful blue light hazards is one of the main advantages of laser TV.
The second advantage of laser TV is that the screen is large and the picture quality is good. "Under the premise of reasonable control of viewing distance, the use of larger size display devices to stimulate visual fatigue is slower." Dr. Zhao Xiaoying said that laser TVs have the advantage of large display size and better visual comfort.
Wang Kai, an authoritative ophthalmologist, assistant dean of the School of Optometry of Peking University Medical College and chief physician of the Department of Ophthalmology of Peking University People's Hospital, also pointed out that when adolescents and children read with different electronic devices, the smaller the screen, the closer the reading distance, and when the reading distance is less than 30cm, it will lead to faster progression of myopia and increase the prevalence of high myopia.
Indeed, according to our own life experience, many children now look at mobile phones, tablets, televisions, etc., not to mention that the distance is too close, and always keep their heads down. This is not only easy to form myopia, but also has a great impact on the health of the child's cervical spine. From this point of view, the reading distance of large-screen laser TV is farther, and the diffuse reflection imaging is softer, so it is more visually friendly and more conducive to myopia prevention and control.
When it comes to laser TVs, I also have my own hands-on experience. About a week ago, I took my children to my little cousin's house and had a good experience of a visual feast created by a Hisense laser TV.
The little cousin's laser TV has just been installed for more than a month, and the projection machine and screen are still brand new and very technological. And the inside of the screen is very thin because there are not so many imaging devices, and it is also beautiful to hang on the wall. My cousin spent more than a month and strongly recommended to me that I switch to a laser TV.
The first time we watched laser TV, we took our children to watch "Bo Niu on the Cliff", which was completely cinema-level viewing and immersion. Even in the lighter environment during the day, the color effect of the red skirt and the yellow bag is also very good, and the picture looks more transparent, more realistic, and layered, and the sensory clarity has also been greatly improved with the increase of color saturation. Coupled with surround sound effects, you can enter the magical world of Miyazaki in one second. After watching the whole movie for nearly two hours, the eyes are completely free of fatigue and sourness, and the children are in good spirits. Had a perfect night.
