Anti-myopia paper, as well as preparation method and application thereof

Abstract

The invention discloses a piece of anti-myopia paper. The anti-myopia paper is characterized by being capable of reflecting colored light with the reflection wavelength of 460-510nm and displaying blue-green color with the luminance of 54%-58%. The paper can be not only prepared by adding a dye into paper pulp but also prepared by printing color on a piece of white paper. The reflection wavelength of the blue-green paper is within a spectral range of 460-510nm, and the color of the paper is darker than white and yellow, so that the colored light reflection is reduced, more colored light can be absorbed, the propor color is strong, the reflection is low and a role of preventing the eyes of students with weak hard light reflecting capabilities from myopia can be played, and the vision of the students is benefited; and the paper is easy to popularize and implement, and the social and economic benefits are obvious.

Description

technical field [0001] The invention relates to an anti-myopia paper, in particular to a paper for preventing myopia by changing the color of the paper to reduce the intensity of reflected light and increase the hue of the reflected light, thereby improving the visual environment and preventing myopia and a preparation method thereof. Background technique [0002] In recent years, due to the thirst for science and technology, people need to read a lot of materials. Students not only need to read a lot of textbooks and extracurricular readings, but also do a lot of exercises. Therefore, the prevalence of myopia remains high. According to relevant reports, among the population of my country, 22.7% of primary school students suffer from myopia, 55.22% of junior high school students, 70.34% of high school students, and 76.74% of college students. In the ranking of the myopia rate of students in the world, the proportion of our country is the second. For this reason, many expert...

Problems solved by technology

The patent No. 98110785 also discloses a kind of paper for short-sighted books, and advocates the use of green paper to print books. These new books do solve the problem of suppressing color vision and reducing vision due to the reflected light of white paper to a certain extent. ability, it is easy to cause visual fatigue and myopia, but the spectrum of reflected light of yellow and green is a wide range. For example, in human vision, yellow, especially yellow with high purity, is all Among the colors, the color that is most likely to cause visual fatigue often causes excessive eye irritation. When working on the display screen, yellow is clearly regarded as one of the backgrounds that should not be used; the spectrum of green reflected light ranges from 530 to 580nm, including light Green, medium green, and dark green. Although there are green cases in the market as anti-myopia workbooks, the standard spectral luminous efficiency of this kind of green (spectrum range is 570-580nm) is ≤0.9154, which cannot effectively prevent myopia. Fatigue and anti-myopia effects
