According to the Shanghai Youth Daily, the average annual incidence of poor eyesight among primary and secondary school students in Shanghai is 53%, and that of senior high school students is as high as 80%. Although schools often educate students to prevent myopia, it has little effect.
At the same time, the poor eyesight of primary and middle school students in Shanghai increases with age. Especially in junior high school, according to the survey, the proportion of poor eyesight will increase by 8 percentage points every year.
In this regard, the Shanghai Municipal Committee of the Democratic Progressive Party stressed that it is imperative to take effective measures as soon as possible to improve students' visual environment, eliminate visual fatigue and protect primary and secondary school students' eyesight. They suggested to the relevant government departments that students should use green and yellow paper for their textbooks and homework.
The education authorities in Shanghai said that education bureau of shanghai will adopt the suggestion of the Shanghai Municipal Committee of the Democratic Progressive Party and promote the use of yellow paper textbooks and books in primary and secondary schools in this city after a certain range of experiments.
Scientific experiments have proved that visual nerve cells are most sensitive to yellow. Under certain conditions, yellow can effectively relieve visual fatigue. According to this principle, using yellow paper with a certain spectral range in books and brochures can improve the visual environment.
