The recurrence of the epidemic has also affected children's learning, sometimes unable to attend classes at school, only online classes at home, but mobile phones, tablets, laptops and other LCD screens, long-term viewing is easy to cause damage to children's vision. Parents urgently need an electronic device that can not only take online lessons, but also protect their children, at this time, the projector has a place to play.
The projector uses reflective imaging, which can effectively reduce eye stimulation and make it more eye-friendly than the LCD screen. Because the child's vision is not yet stable, watching the LCD screen for a long time, the light directly into the eyes, will cause irritation to the eyes, affecting the child's vision. In life, why avoid letting children watch mobile phones, computers, and televisions for a long time? Here's why!
Diffuse reflection imaging of the projector, the light source is first projected onto the wall or curtain, and then reflected into the human eye, the child's eyes will not directly look at the light source. Compared with the LCD screen where light directly enters the human eye, the projector can reduce visual fatigue to a considerable extent.
At the same time, the screen brightness of the projector is lower than that of the LCD screen, and the visual effect is relatively softer, which will also play a role in reducing eye stimulation.
Secondly, the projector screen size is larger, the viewing range is wider, and different sizes of pictures can be projected according to the distance of the projection distance.
Compared with mobile phones, laptops and other devices, the large size of the projector can increase the proportion of the picture of the field of view, and the child does not need to stare at a fixed area when watching, and the eye activity is stronger.
However, when using the projector, it is also necessary to combine the correct viewing distance and eye habits, the viewing can not be too close to the wall and the curtain, after a period of time, pause for a rest, so that the child's eyes get a full rest.
The projector combines multiple features such as high definition, diffuse reflection imaging, and intelligent operating system, which is an electronic device suitable for giving children online lessons and better protecting children's vision.
