Description

Technical Field

[0001] The invention relates to the technical field of cultural products, in particular to an anti-myopia exercise book. Background Art

[0002] Exercise books are an indispensable cultural product for students in their current learning process. Students can record the knowledge taught by teachers on them.

[0003] However, the existing exercise books still have the following technical problems when used:

[0004] Myopia is the most common refractive error eye disease in the world, and a considerable proportion of it is caused by student myopia. Moreover, the prevalence rate increases significantly starting from fifth and sixth grade of primary school. The paper of existing exercise books is white and smooth, which can almost reflect the original spectrum and intensity of white illumination into the human eye. Students are very likely to develop myopia if they use existing exercise books for a long time.

[0005] For this reason, a kind of myopia prevention operation is now proposed to originally solve the problem proposed above. Summary of the invention

[0006] The object of the present invention is to provide an anti-myopia exercise book to solve the problems raised in the above-mentioned background technology.

[0007] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an anti-myopia exercise book, comprising a first cover and a second cover, the first cover is arranged at the front end of the second cover, the left ends of the first cover and the second cover are commonly connected with a side edge, the interior of the first cover and the second cover are fixed with evenly arranged paper pages, and the side walls of the paper pages are provided with an anti-myopia coating.

[0008] Preferably, a protective cover is fixed to the front end of the first cover, and an information label is arranged inside the protective cover.

[0009] Preferably, an elastic limiting belt is fixed to the rear side of the first cover.

[0010] Preferably, a storage shell is fixed to the upper end of the front side of the second cover, a limiting rod is laterally fixed inside the storage shell, a movable tube is slidably provided outside the limiting rod, a bracket is fixed on the front side of the movable tube, a vertical rod is longitudinally fixed inside the bracket, a pressure plate is slidably provided on the rod wall of the vertical rod, a spring is sleeved on the outside of the vertical rod, one end of the spring is fixedly connected to the side wall of the pressure plate, the other end of the spring is fixedly connected to the inner wall of the bracket, and the rear side of the pressure plate contacts the front side of the paper sheet.

[0011] Preferably, a tearing opening is provided at the left end of the paper sheet side wall.

[0012] Preferably, evenly arranged anti-slip strips are fixed to the rear side of the second cover.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] The present application provides an anti-myopia coating on the surface of the paper page. The color of the coating is yellow. The paper can absorb part of the short-wavelength blue light, reducing eye fatigue, thereby effectively preventing myopia when students use exercise books for a long time.
