With the summer holidays now upon us, many students and children are finally enjoying their holiday life, but this also makes many parents worried. Indeed, many children have been deeply affected by the sudden onslaught of the epidemic this year. Because they can’t start school, many children have been staying at home. Reading books and learning to play games, plus many children began to study online at home, resulting in a significant decline in children’s eyesight, so that children’s vision problems deserve attention. And now that the holidays are here, how can children’s vision problems be protected?
Vision problems deserve attention
It is undeniable that eye health problems have become more and more prominent in recent years, especially dry eyes, astringent eyes and eye fatigue have become more and more frequent. Dry eyes and fatigue not only affect study and work, but also normal life, which makes more people start to pay attention to eye health. Together with improper use of eyes by children and teenagers, the problem of myopia among teenagers is even more serious.
According to a study by the World Health Organization, there are 600 million myopia patients in China, and the myopia rate among teenagers is the highest in the world. The myopia rate of high school and college students has exceeded 70% and is increasing year by year, and the myopia rate of elementary school students is also close to 40%.
Projectors are a better choice
As technology continues to evolve, there is an endless variety of display devices. In terms of imaging principle, the projector can be said to be a relatively eye-friendly display device. Here to give you a brief introduction, the imaging principle of the projector is the light machine projection screen to the wall or curtain, and then by diffuse reflection to the human eye. Compared to the backlight of the LCD screen direct light, diffuse reflection of light although the brightness is attenuated, but the stimulation of the human eye is smaller. Therefore, the visual fatigue during prolonged use will be alleviated.
So is watching a projector necessarily not harmful to the eyes? In fact, it is not, whether it is a projector or LCD TV will radiate blue light. And in the projector, although diffuse reflection will weaken the blue light, but still exists, so if you do not pay attention to the correct eye hygiene, there is still the risk of visual fatigue leading to vision loss. This stimulus is only weakened compared to LCD TVs.

Finally, after the relevant experimental data show that the projector can indeed alleviate the degree of eye fatigue to a certain extent, so that as long as when we open our eyes all the time, we need to let the eye muscles relax at the right time, whether it is a projector or LCD TV, prolonged viewing will lead to the phenomenon of visual fatigue, so we need to focus on avoiding the appearance of visual fatigue, rather than watching or not watching TV programs on. It is also true that projectors are more friendly to people’s eyes than LCD TVs, but it does not mean that projectors can protect the eyes.
Functionally more suitable for children to watch
For those young home users, oversized LCD TVs are often not conducive to installation. And they are also not conducive to handling during transportation, and some residential elevators can’t even fit large LCD TVs. And compared to these projectors are more compact, and has no less than the LCD TV audio-visual experience, so we say that the projector in some respects is to be more than the LCD TV advantage.
And the past projection in the installation of the use, need to lay a good audio line, video lines, etc., and finally connected to the content source and audio to be able to use, the process is not only cumbersome, and the best in the decoration before the good, or take the bright line will affect the interior aesthetic degree. Nowadays, the projector not only comes with a rich content source, but also a built-in internationally renowned audio system, so that users can buy it and use it, without having to consider other factors. Such a simple and easy to use product will naturally attract more users to buy. For children, where the projector is placed, where is the place of entertainment.
Many projectors are now equipped with a very intelligent system, and the built-in film and television resources are very rich. Even some systems have integrated more than two content sources, which basically have a special animation section as well as a children’s section, the children’s choice is very rich. The voice recognition gives different permissions to different family members, parents can directly enter or exit the encrypted children’s desktop through voice, children can not launch the children’s desktop through this function, parents are not around to worry about children exposed to undesirable information, this time you can finally rest assured that the remote control to the children.
Written in the end
Finally, a comprehensive view, the projector compared to computers, cell phones, LCD TVs and other electronic devices, can effectively reduce the damage to the eyes of direct screen radiation. In the advent of summer vacation, want to protect children’s eyesight, the projector is undoubtedly a better choice. The eyes are the windows to the soul, children’s eyesight problems must not be ignored.
