Description

Myopia-preventing paper

Technical Field

The invention belongs to the technical field of myopia prevention paper, and particularly relates to myopia prevention paper.

Background

Myopia is the eye disease with the highest global incidence of ametropia at present, and juvenile myopia accounts for a considerable proportion of the eye disease, and the prevalence rate of the myopia obviously increases from the fifth and sixth grade of primary school. At present, a great deal of research is carried out on the occurrence reasons and the influencing factors of the myopia of the teenagers, and the fact that the myopia of the teenagers is caused by long-time short-distance work is proved. The eyeball of the teenager is in a growth and development stage, the extensibility of the spherical wall is large, the external muscles of the ken (mainly internal rectus muscles) apply certain pressure on the eyeball through short-distance work such as long-term reading and writing, the intraocular pressure is correspondingly increased, the ciliary muscles and the external muscles of the eye are always in a high-tension state and continuously contract and can not relax for a long time, the spherical wall gradually extends, the axis of the eye is elongated, and the degree of myopia is increasingly deeper.

In the prior art, the purpose of preventing myopia is achieved by adding pigment in the papermaking process and changing the brightness display mode, but the roughness of the printing surface of the page of the paper is very small, the smaller the roughness is, the larger the reflection factor of reflected light is, the greater the stimulation to eyes of people is, and the myopia prevention effect is poor.

In patent No. CN200910117251.7 entitled myopia prevention book and its printing method, the roughness of the printed surface of the page is increased by printing the ink coating layer visible to the naked eye on the surface of the paper, and the reflection factor of the reflected light of the page is reduced, so as to reduce the stimulation of the reflected light of the page to the eyes.

Compared with the prior art, the invention has the following beneficial effects:

(1) the ink coating is printed in a vertically staggered mode, the reflection factor is greatly lower than that of common paper, eye muscles are enabled to move passively, long-time eye fatigue is prevented, myopia is prevented, all paper for the front cover and the inner core is made of the raw materials without fluorescent agents, all inner pages of all products are printed by a brand-new antibacterial water-based ink material technology, and the antibacterial efficiency is high; through the ink coating that sets up crisscross from top to bottom, whole paper prints, can save at least half the printing ink quantity, uses and has both reached the effect of myopia prevention, has saved printing ink again.

(2) The ink coatings printed on the A surface and the B surface of the same sheet of paper are staggered up and down, namely the ink coating printed on the back surface of the myopia-preventing paper is positioned at the blank position in front of the myopia-preventing paper.
