Tablet PCs should not be suitable for children

According to the “Health News” report, with the Tablet PC popular, many parents give it to children as gifts or prizes. Colorful, game-rich and portable tablet computers allow children to enjoy happiness while also unknowingly bringing them potential harm.

When we look at things, the eyelids are moving in a regular manner, like a wiper in a car. They constantly apply tears to the surface of the black and white eyeballs (cornea and conjunctiva) to provide lubrication. Under normal circumstances, the number of eyelid movements is 15 to 20 times per minute, but when you look at a computer, especially when you are highly concentrated on playing games, the number of blinks will be greatly reduced, and the appearance of chapped eyes will appear over time.

In addition to inducing dry eye syndrome, another important adverse effect of the computer on the eyes is that it may induce myopia and visual fatigue. In the computer products, the brightness of the tablet computer is higher than that of the ordinary computer, and the coloring is more splendid, so it is more prone to visual fatigue. The ciliary muscle of the eye is overly constricted. It is called a ciliary muscle spasm in the medical field. A pseudo-myopia occurs, such as a pseudo-myopia that may be recovered in time for a rest, and it may become true if the time is too long.
