Abstract

The invention relates to the technical field of school supplies and discloses an exercise book capable of preventing shortsightedness. The exercise book comprises a plurality of inner pages, magneticpowder, first ink coatings and second ink coatings, wherein the inner pages are disposed between two symmetrical covers, and the inner pages are in color capable of preventing shortsightedness; the magnetic powder is disposed on the two covers through adhesives, and the two covers can be mutually attracted through the magnetic powder; each first ink coating is disposed on the corresponding inner page, and the colors of the first ink coatings are different from those of the inner pages; and the second ink coatings are disposed on the first ink coatings or the inner pages. Under the condition ofno influence on normal use, the roughness of printed surfaces of the inner pages can be improved, the reflection factor of reflected light of the pages is lowered, thus stimulus of the page reflectedlight to eyes is reduced, the shortsightedness is prevented more effectively, corners of the exercise book are prevented from being folded when the exercise book is not in use, meanwhile students canbe reminded of making the exercise book moving upwards, and thus the a certain distance between the eyes and the exercise book can be kept.
