Yellow notebook preventing myopia

Abstract

The invention discloses a yellow notebook preventing myopia. The yellow notebook comprises a cover and myopia-preventing paper. The myopia-preventing paper is yellow paper, the wave length of the reflected light of the yellow paper ranges from 580 nanometers to 595 nanometers, and the brightness of the yellow paper ranges from 60 percent to 85 percent. According to the yellow notebook, due to the fact that the yellow paper with the wave length of the reflected light of 580-595 nanometers is adopted, the yellow notebook can effectively absorb blue light and purple light, only the reflected light with the specific wave length can be reflected due to absorption for the blue light and the purple light, and myopia caused by color vision weakening due to the fact that the reflected light burns the retina is avoided. The brightness of the paper is controlled within 60 percent to 85 percent, the bright difference between the paper and characters can be reduced as much as possible on the premise of guaranteeing clear reading, the restraining for the color vision is reduced, fatigue is relieved and delayed, and myopia occurrence is reduced; the yellow notebook can effectively promote self healing of people with pseudo myopia.

Description

technical field [0001] The invention belongs to the field of papermaking, in particular to a yellow book for preventing myopia. Background technique [0002] According to reports, the incidence of myopia among teenagers in my country is as high as 60%, ranking first in the world, and it is also increasing at a rate of 10% per year, which has aroused people's great concern. The main reason for the onset of myopia in teenagers is that teenagers are under too much study pressure. Teenagers need to face books for a long time in order to study, and they use their eyes too hard. [0003] At present, there are two mainstream views on the causes of myopia. The first point of view is that due to the use of white paper, white paper has full-frequency reflected light, and white paper and text can cause the maximum brightness contrast. Due to the self-regulation of the human eye, when the brightness contrast is too large, the human body will automatically suppress the color vision of t...

The second point of view is that white paper has full-frequency reflected light, among which blue light and violet light will burn the retina. Due to the loss of the retina, the color vision function will be weakened, which will cause myopia.
