Why do children use tablets?

It is understood that the tablet computer is a direct illuminator with bright colors and strong visual stimulation. Long-term use will easily lead to damage and pathological changes of retina and macula, decrease the sensitivity of vision and color vision, and even cause irreversible damage to the immature optic nerve of children. Children are in the period of growth and development, and the ciliary muscle, which is responsible for adjusting the distance, is relatively strong. Seeing too close, especially using the tablet computer for a long time, will cause visual fatigue, affect the focusing function of the eyes and induce myopia. In the long run, it will also cause amblyopia or strabismus. It can also cause dry eye. Under normal circumstances, people's eyelids blink every minute 15-20 times. But when watching the computer, especially when playing games with high concentration, the number of blinks can be reduced to 2-3 times. The result of blink reduction is excessive evaporation of tears, non-wetting of the eye surface, and cracking of the eye surface over time.

If the screen of the tablet computer is too small and the resolution is too low, it will also increase the burden on the eyes and cause visual damage. Because the smaller size will narrow the line of sight, children will close the distance from the screen again in order to see the screen clearly, and the screen with low resolution is more likely to lead to visual fatigue.

The source of visual damage of tablet computers is naturally the screen. Fortunately, domestic children's tablet manufacturers have realized this, and the super learning for children's tablet babies has performed well in many places, which is worth learning from domestic children's tablet manufacturers. For example, in order to prevent the screen from damaging children's eyesight, the baby's ultra-high learning book uses the same 8-inch 1024×786 resolution IPS screen as Apple's iPad2. This specification has been tried and tested repeatedly. At the same time, the size, aspect ratio, contrast, brightness, dpi and light source type of this screen have been scientifically optimized, which can effectively prevent eye fatigue.

In addition to the screen, the supervision of use time is also a headache for parents, because excessive use of eyes can also damage vision. You can't supervise children if you are not around them, but even if you are around them, you can't always remember to remind them to rest. Baby Bonus Super School has obviously considered this point, so it has specially joined the worry-free management of parents, which can set the duration of each use and forcibly control the time for children to use the tablet. In fact, baby bonus super learning is not an entertainment tool, but a learning tool, but learning in the form of play. Interesting learning will make children more obsessed with tablets. In order to prevent overuse of eyes, parents' worry-free management is very necessary.
