Frequent use of electronic screens No amount of blueberries or carrots will save your child's eyes
With the continuous advancement of science and technology, different teaching modes and methods have been born. Among them, electronic wisdom assisted teaching has become a very convenient means. In addition to daily offline teaching, major schools will also widely carry out electronic smart classrooms. This gives children a lot of time to spend with electronic screens, and the risk of myopia increases.
The electronic screen has been used for a long time, and the eyes are really hurt.
According to the Ophthalmology Branch of the Chinese Society, 63 of the 700 million myopia patients in China are5% of vision loss is due to blue light damage. Short-wave blue light with a wavelength between 400nm and 450nm can penetrate the lens directly to the retina, causing damage to retinal cells. Electronic products such as computers, iPads, and mobile phones all emit this blue light. Moreover, the younger you are, the more harmful this blue light is to your eyes. This is why parents have been urged to keep their children exposed to electronic products as little as possible.
Eating blueberries and carrots is unreliable.
Since childhood, we have heard our parents say that "pig liver brightens the eyes", but in fact, although pig liver is rich in vitamin A, it cannot relieve visual fatigue, let alone improve myopia.
There is also the saying that "eating fish eyes to supplement eyes" is also unreliable. In addition to water and fat, what remains of the fish is a small amount of vitamin A and DHA, and the so-called "what to eat and what to supplement" is just a psychological comfort.
Some vegetables and fruits, such as goji berries, carrots, blueberries, etc., although these things do contain ingredients that are good for the eyes, don't expect to eat something to make your eyes healthy after working hard.
In the face of this situation, how to solve it.
You have to choose a large screen. Different electronic devices can cause different damage to a child's eyes. Generally speaking, the order of choice is: projector, TV, desktop computer, laptop, tablet, mobile phone. In a word, choose the big not the small. The words on the screen should also be big rather than small.
Look less. Parents must control the amount of time their children spend looking at electronic devices: 20 minutes each time for elementary school students, 2 per day5 hours; 30 minutes per session for secondary school students, 4 hours per day. When you are not taking online classes or doing homework, you can accumulate 1 hour per day of using electronic devices.
It is necessary to soak up the sun more "eyes".
Sunlight is a good medicine to prevent myopia. Outdoor activities can relax children's eyes and reduce the fatigue of reading books for long periods of time. At the same time, outdoor activities also help children exercise and strengthen their physical fitness. Outdoor exercise or walking for at least two hours a day can not only relieve children's learning pressure, but also effectively prevent the occurrence of myopia.
Starting from nutrigenomics, the targeted photon R&D team has conducted in-depth research on 305 genes and 1435 SNP sites related to vision development, and used biophotonic technology to develop the flagship product of the biophotonics series - the elf photoculture instrument. According to the composition ratio of 9 light-dependent opsins of human vision-related cell chromosomes, the elf photoculture instrument optimizes the ratio of different frequency bands of the spectrum, and adopts high-performance LED light source, which is processed by imitation lumens secondary optics to achieve accurate and rapid adjustment and improvement of shape, light and color vision. In addition, the customized spectrum of the product can supplement the light nutrition around the retina through diffuse reflection, improve the oxygen-carrying capacity around the eyes, promote tear secretion, and supplement enough eye light nutrition for children, which has a very positive impact on their myopia prevention and control.
Targeted photon ingenuity creates targeted aesthetics. Add more modern design elements to the new generation of elf light cultivation instrument: not only has a double fashion color matching to meet the aesthetic needs of modern people, but also has a built-in power supply for easy movement, and can turn on eye light care anytime and anywhere. The device is also specially designed with forehead support and forehead stickers to take care of the user's head and chin, making light cultivation more comfortable; The height adjustment of the three-level biological light source allows different users to perfectly adapt to the height of the core area of the device, making the light cultivation more accurate.
