Abstract: now there are many students’ homework books on the market. The paper is light yellow or light green. Such paper has low reflectivity when sensitive to light, which can well protect children’s eyes and eyesight. Professor Min suggested that students should also use these two colors in textbooks., The state will issue a whiteness standard for paper products next year, which stipulates the maximum whiteness (brightness) of paper and paperboard. Any product exceeding the limit is unqualified., The whiter the paper, the better. The professor explained that when light strikes the paper, the reflected light waves from the surface enter the human eye and form an image on the retina. If the paper is too white, the stronger the reflection will be, which will damage the photoreceptor cells of the retina. Over time, it will cause irreversible vision loss., The professor pointed out that pupils’ eyes have not been completely shaped, and they are more likely to form functional regulatory myopia after being stimulated for a long time, so as to induce or accelerate the development of myopia., Now there are many students’ homework books on the market. The paper is light yellow or light green. Such paper has low reflectivity when sensitive to light, which can well protect children’s eyes and eyesight. Professor Min suggested that students should also use these two colors in textbooks., If the child’s eyesight fluctuates greatly, it is likely to be functional adjustment myopia, that is, pseudomyopia., The professor reminded that mydriatic drugs can be used to alleviate functional regulatory myopia.

country will issue a whiteness standard for paper products next year, which stipulates the maximum whiteness (brightness) of paper and paperboard, and all products exceeding the limit are unqualified.
paper is not the whiter the better. The professor explained that when light strikes the paper, the reflected light waves from the surface enter the human eye and form an image on the retina. If the paper is too white, the stronger the reflection will be, which will damage the photoreceptor cells of the retina. Over time, it will cause irreversible vision loss. Professor

there are many students’ homework books on the market. The paper is light yellow or light green. Such paper has low reflectivity when sensitive to light, which can well protect children’s eyes and eyesight. Professor Min suggested that students should also use these two colors in textbooks.
if the child’s visual acuity fluctuates greatly, it is likely to be functional regulatory myopia, that is, pseudomyopia. Professor

remind that mydriatic drugs can be used to relieve functional regulatory myopia. Dropping 1 ~ 2 drops before going to bed every day can play a good role in relaxing the ciliary muscle. The efficacy of this medicine can last for 5 ~ 6 hours without affecting the daily life. It can also be applied to students, but it should be used under the guidance of doctors.
