A few days ago, a mother wrote a private letter to Uncle Zhai, saying that the exercise books distributed by the school are all light green. Can this really protect the eyes?

In theory, it is difficult for an exercise book to protect the eyes.

The essence of eye protection is to let children's eyes get enough rest.

If you have to talk about eye protection, the only way to protect your child's eyes may be to let your child do less homework.

At present, there is no authoritative paper or clinical study to prove that green eye care, and few doctors believe that green eye care.

It exists in people's word of mouth, but in fact, it is passed on, so it misses the "key point".

Because, the real eye protection is not green, but vision.

Working and studying close for a long time, the eyes are prone to fatigue and dryness, and looking into the distance where the field of vision is open can regulate the ciliary muscle and lens, reduce visual fatigue, prevent myopia and control the development of myopia.

In computer eye protection mode, most of the time, the screen is set to bean green, but electronic products such as computers are harmful not only because of the screen color, but also for other reasons:

The brightness difference between the surrounding environment of ① and the display is too big, which is easy to increase the burden of vision.

② browsing too much information leads to continuous changes in light and shadow, which will cause continuous irritation to the eyes.

③ will pay more attention to fatigue due to improper sitting posture and being too close to the computer screen.

④ pays too much attention to work and play, thus neglecting to blink and rest, resulting in dry and tired eyes for a long time.

Therefore, it is simply not enough to set up the so-called "eye protection mode" to achieve the purpose of protecting the eyes. Uncle Zhai suggested that:

Usually try to use the computer in bright places, and adjust the screen brightness according to the surrounding light environment, so that the comfort of the object shall prevail.

Maintain correct sitting posture, reduce continuous high-intensity eye use, close your eyes and rest or overlook for 5 minutes every 0.5 hours of work, consciously increase the blinking times and prevent dry eyes from fatigue.

Green is not the protective color of the eyes, and don't worry about how to set the "green eye protection mode" of the display. Adequate outdoor activities and good eye habits are the correct and effective "eye protection mode".
