I bought three eye protection desk lamps, two children's learning desks and 1 eye protection learning machine, just to create the most convenient and comfortable learning environment for children, and parents of prospective pupils can share their eye protection experience.
Many parents are afraid that their children will lose at the starting line. Since kindergarten, they have reported many training courses for their children, such as English enlightenment, pinyin literacy, thinking training, mathematics enlightenment, art enlightenment and so on. Later, due to the epidemic, offline classes became offline classes, and children spent a lot of time staring at electronic screens every day. In the long run, the eyes are not fully rested, and symptoms such as congestion, soreness, dryness and itching are prone to occur.
Watching the electronic screen for a long time, using the eyes at close range for a long time, spending less time outdoors and failing to meet the standard of lighting conditions are the main reasons why myopia is getting younger and younger.
The priority is learning machine, projector, TV, desktop computer, notebook computer, tablet computer and mobile phone.
The distance between the eye and the object is directly related to the tension adjusted by the lens. Under normal circumstances, when you see an object 6 meters away, the adjustment of the eyeball is basically in a static state. The closer the distance between the eyes and the object, the higher the accommodation ability of the lens. For example, it takes 1 degree to look at objects at a distance of 1 meter, 2 degrees to look at objects at a distance of 50 cm, 4 degrees to look at objects at a distance of 25 cm, and 8 degrees to look at objects at a distance of 10 cm. Long-term close-up use of eyes can easily change ciliary muscle tension and lens refraction, and then lead to myopia.
Therefore, it is more appropriate for children to choose large-screen and high-resolution electronic products for online classes. You can see clearly even if you sit far away, and avoid using your eyes at close range for a long time to the maximum extent.
In addition, the brightness of the electronic screen should not be too bright or too dark, and the eyes should be comfortable. The placement of electronic screens should try to avoid the direct exposure of windows and lights, so as to avoid the reflection of the screen and aggravate the irritation to the eyes.
Parents should strictly control the time for their children to use the electronic screen continuously. 0 6-year-old children should avoid using electronic products as much as possible, and primary and secondary school students should use electronic products for no more than 15 minutes each time and no more than 1 hour every day. The younger the child, the shorter the continuous use of eyes should be.
When you must use the electronic screen, you should strictly follow the "20-20-20" principle, that is, when using electronic products every 20 minutes, you should look out 20 feet (about 6 meters) for at least 20 seconds. During the online class break, be sure to urge the children to go to the window and overlook or close their eyes so that their eyes can get a full rest.
Lying down or looking at the screen with your head tilted will lead to persistent congestion of the eyeball, increased intraocular pressure, prolonged posterior part of the eyeball wall and elongated axial length, which will lead to myopia. Therefore, children must sit up straight on the Internet.
Adequate outdoor activities are one of the most effective ways to prevent myopia. Generally speaking, primary and secondary school students need outdoor activities for 2 hours every day, which is about 14 hours per week. Parents should take their children outdoors when they are free, and stay away from "electronic nannies".
Generally speaking, preschool children should sleep for more than 1 1 hour, primary school students1hour, junior high school students 9 hours, and senior high school students at least 8 hours. Pay attention to a balanced diet, eat more fish, dairy products, eggs, bean products and vegetables, and eat less sweets.
Don't look at the electronic screen in too bright or too dark light. When the indoor light is insufficient, you can turn on the ceiling lamp and eye protection desk lamp at the same time to ensure that children learn in an environment with sufficient light and suitable color temperature.
Urge children to develop the habit of doing eye exercises to relax, and insist on doing eye exercises twice a day, once in the morning and once in the afternoon. Continue to do eye exercises after using your eyes to relax your eyes. But it should be noted that you must wash your hands before doing eye exercises.
When children frequently have eyes askew, squint, squint, or symptoms such as dry eyes, foreign body sensation, burning sensation, itching, photophobia, pain, etc. Be sure to take your child to the ophthalmology clinic as soon as possible, so as not to delay the illness!
My lovely family loves reading, and he can be seen reading quietly everywhere in the living room, balcony and bedroom. But the lighting conditions in the living room and bedroom are not bright enough. Sometimes, in order to see the contents of the book clearly, children will unconsciously bow their heads and approach when reading it.
So I have an eye protection desk lamp in the place where children often read books: one on the sofa, one on the study desk and one on the bedside table in the bedroom.
The selection of eye protection lamps can refer to the following standards:
The height and weight of children change every year. Fixed desk and chair height and desktop angle are not only uncomfortable to use, but also easy to hurt children's bones and eyesight. When reading and writing, children are prone to head tilt, shoulder tilt, waist bending, chest sticking to the edge of the table and other bad sitting postures, which will not only seriously reduce the efficiency of children's homework, but also cause myopia, strabismus, hunchback, scoliosis, chest deformity, finger deformation and other problems.
Therefore, it is necessary to choose a suitable children's study table with adjustable desk and chair height and adjustable desktop inclination.
The following criteria can be referenced in the selection of the study table:
As far as I know, most children use these devices for online classes at home: mobile phones, iPad, computers and televisions. Regardless of the screen size, whether there is stroboscopic problem or not, these devices have the same disadvantage: they are prone to glare. That is, when the external light source is bright, the screen will reflect light like a mirror, which will stimulate the eyes and make the contents displayed on the screen blurred.
The main learning tool in my family used to be iPad, which was used for online classes, playing Go and watching cartoons. But after a long time, I always feel that my eyes are dry and sore, and I also have symptoms of frequent blinking.
IPad and TV can see reflections, but E3 can't.
In order to enable Aiduo to concentrate on online courses, I recently bought him a bigger and more eye-protecting e-learning device-class screen E3.
The screen of lesson screen E3 is quite different from the ordinary electronic screen in terms of perception and touch. The screen is made of special film and combined with AG nano-etching, which avoids the visual impact caused by ambient light and specular reflection, and makes children look at the electronic screen as easily as paper.
2 1.5 inch screen, children can see clearly from a distance in class. Generally speaking, the distance between the eyes and the computer is at least 40cm when using the computer to surf the Internet. The distance between eyes and TV is more than 3 times the diagonal of TV screen. The diagonal of lesson screen E3 is 54.62cm. According to scientific calculation, children can study as far as possible by sitting at a distance of 1.6 meters.
In addition, the lesson screen E3 has the functions of eye protection, intelligent dimming and AI ambient light detection, which can be said to be an upgraded version of the intelligent light perception in the learning machine. Will automatically detect the surrounding ambient light, prompting whether the light brightness is appropriate; Screen brightness will automatically match the environment, reducing the occurrence of eye fatigue during learning; Passed TUV Rheinland low blue light without strongpoint certification, and has ultra-low blue light mode to choose from; With its own vision detection function, you can monitor your child's vision changes anytime and anywhere.
Of course, as a parent of a prospective primary school student, in addition to the massive online classroom resources and regular eye protection functions, I am also very concerned about its auxiliary functions, whether it can help me prepare my children before class and provide after-school counseling. The synchronous tutoring of E3 is very easy to use: there are textbooks for Chinese, mathematics, English, physics, chemistry and other subjects, which can give children the most comprehensive guidance before and after class.
Before Edo went to primary school, I borrowed a fifth-grade foreign language textbook from my neighbor's house to try it out. Unexpectedly, text explanation, knowledge expansion, word spelling, dictation after class and intonation proofreading are all available. Even if parents don't have time to accompany their children when writing homework, they can finish it efficiently by themselves.
Having said that, many parents may worry that there are too many APP resources in the learning machine, which will distract children's learning attention and fascinate them. After all, children are still young and their self-control ability needs to be strengthened.
The small class screen E3 also takes this problem into account, so it specially sets up the function of parents accompanying students. Not only can you check the children's use time in real time on the mobile phone, but parents can also set the use time and available time of the whole machine for children with insufficient self-control ability, and set the use time of each learning APP separately to effectively control the use time of the children's electronic screen.
Generally speaking, if you want your child's eyes to be less hurt, you should not only choose appropriate learning tools, but also balance nutrition and combine work and rest to effectively prevent myopia.
