[0017] Further describe in detail below in conjunction with accompanying drawing:
[0018] see figure 1 A yellow book for preventing myopia, comprising a cover and anti-myopia paper, wherein the anti-myopia paper is yellow paper, the wavelength of reflected light is 580-595 nanometers, and the brightness is 60%-85%. The present invention can effectively absorb blue light and purple light by using yellow paper with a reflected light wavelength of 580-595 nanometers, and only reflect reflected light of a specific wavelength through the absorption of blue light and purple light by the paper, thereby avoiding color vision caused by burning the retina due to reflected light Weakening leads to the occurrence of myopia. In addition, by controlling the brightness of the paper at 60% to 85%, the invention can reduce the brightness contrast between the paper and the font as much as possible and reduce the suppression of the color vision function under the premise of ensuring clear read...
