Why can light yellow paper protect your eyesight better than white paper?
This "myopia prevention book" (yellow paper with reflection spectrum of 550 nm-6 10 nm, also called yellow exercise book) invented by teacher Lu Naichi of Zhou Pu Middle School and made according to the patent of this invention has just passed the expert appraisal. The appraisal results show that schools in this city should abandon the white exercise books that have been used for decades and use yellow exercise books instead. Experts use scientific theory to explain that the spectrum of 550 nm reflected light is the most sensitive spectrum for vision and the most acceptable spectrum for eyes, that is, the eyes are least tired and can see clearly. After comparative experiments, experts from Shanghai Eye Disease Prevention and Control Center believe that the Yellow Book can effectively prevent and delay eye fatigue and can be used as one of the important means to prevent and treat students' myopia.
