[Reprint] Do primary and secondary school students use white paper or yellow paper to find the answer?

In recent years, the incidence of myopia among primary and secondary school students has remained high. After investigation and study, it may be related to the paper color of textbooks and notebooks used by students for a long time, but which is better, white paper or yellow paper? People have different opinions, some say that white paper is good, it looks clean and comfortable, and black and white are clearer; Some say it is better to use yellow paper, because bleaching agent may be added to the white paper in the production process, which will be more eye-consuming, easy to cause visual fatigue and not conducive to eye health. Yellow paper, on the other hand, is slightly dim and will protect your eyes when used.

For the above two diametrically opposite views, the author is more inclined to agree with the latter.

According to the investigation, some bleaching agents and corrosive chemicals were indeed added to the white paper in the production process. Although the pulp has been washed and filtered, there are still many chemical components harmful to human body. Another point is that white paper reflects white light, which has the greatest visual brightness, and it is most likely to cause visual fatigue when used, thus affecting children's vision. Compared with white paper, yellow paper has lower visual brightness, and there is no bleach in it. Of course, it doesn't mean that we are safe as long as we use yellow paper (yellow paper here refers to yellow paper with a certain brightness, and the color is too dark, which will be harmful to the health of our eyes. )。 It should be pointed out here that yellow paper with a specific brightness has the smallest reflection spectrum and can cause the strongest color perception with the smallest light wave. Although its visual brightness is slightly lower than that of white, the visual environment it creates is relatively comfortable and safe.

Therefore, experts suggest that students should choose yellow with certain brightness for books and brochures.
