Abstract

A book for preventing myopia features that its each page is printed by a base color, which optical wavelength is 510-610 mm for eliminating the useless reflected light from page and relaxing vision fatigue, so preventing myopia.

Description

Myopia preventing book and typography

Technical field:

The present invention relates generally to the books for taking notes or keeping accounts of teaching usefulness, particularly myopic-preventing books for taking notes or keeping accounts and typography thereof.

Background technology:

In recent years, because to the craving for of science and technology, people need read wide variety of materials, the student not only needs to read a large amount of textbooks and outside reading, also will do a large amount of exercises, and myopia prevalence is high for this reason.According to relevant, in China's population, the pupil suffers from bathomorphic patient and accounts for 22.7%, and the junior school student is 55.22%, and the high school student is 70.34%, and the university students is up to 76.74%.In the ranking of world's myopia of student rate, second of the ratio row of China.Numerous for this reason experts carries out research and analysis to this, think all that generally vision can produce fatigue phenomenon after the work for a long time, many suggestions and way have been proposed, these ways are to be purpose with eyes that change light or adjustment, maintenance people and the distance of reading thing mostly, and have designed some devices.Recent years, people have proposed the view of some new pre-myopia preventions, think that vision produces tired color with the reading thing direct relation is arranged, and are green more suitable with yellow.The patent No. is 95111654 patent disclosure, and a kind of myopic-preventing book is thin, and the reflected light that has proposed " in different visual angle environment, the visual angle ability is different with degree of fatigue " white book printing paper can suppress the colour vision function, reduce visual capacity; The blank sheet of paper reflected light can cause maximum visual angle fatigue when causing the high-high brightness contrast, this fatigue environment is easy to cause myopia.To advocate to use yellow paper to print student's book thin for this reason.The patent No. is that 98110785 patent also discloses a kind of vision-protection book paper, and it is thin to advocate to use green paper to print book.Think and use the paper of 540-570nm can be beneficial to the normal performance of viewing function, and can keep good visual angle mental status.These new books are thin have been solved really because the reflected light of white paper suppresses the colour vision function, reduces visual capacity, very easily causes visual fatigue, causes the problem of myopia easily.But some new problems have been brought simultaneously again, because the restriction of paper color, papermaking enterprise will increase technology on the one hand, the papermaking cost improves, the thin volume of student cost improves thus, increased the weight of parents of student's burden, brought very big inconvenience to printing enterprise on the other hand, a large amount of blank sheet of paper of normal use can not be used.

Summary of the invention:

The objective of the invention is to avoid the deficiencies in the prior art part and a kind of myopia preventing book and typography are provided.

Purpose of the present invention can be by realizing by the following technical solutions: a kind of myopia preventing book, include the page (1) that is assembled into books for taking notes or keeping accounts, its main feature is to go up the background color (2) that printing is arranged between pattern, literal, form and the books for taking notes or keeping accounts page (1) that prints at the books for taking notes or keeping accounts page (1); The spectral wavelength of background color (2) is 510-610nm.The optimal spectrum wavelength of background color (2) is 530-580nm.

The present invention changes the color of reading thing by printing, and makes and reads the coloured light that thing reflects specific frequency spectrum, to create the visual environment of safety and comfort, alleviates visual fatigue.According to relevant bibliographical information, pseudomyopia can be recovered in good visual environment normally voluntarily, and true myopia is no longer deepened.

According to relevant document introduction, people's eyes are differentiated the representative theory of color and are mainly contained two classes, trichromatic theory according to poplar-Helmholz, contain three kinds of dissimilar pyramidal cells on the human eye retina, contain three kinds of different visual pigments respectively in these three kinds of pyramidal cells, be called blue, close green, the close red-out pigment of parent.When entering human eye, the ambient light radiation absorbed by their absorption characteristics separately by these three kinds of pyramidal cells, produce photochemical reaction behind three kinds of pigment absorption light, cause neural activity, reach nerve centre through bipolar cell and ganglionic cell, brain produces color perception with these informixs.The plain excitation time of for example close red-out produces red sensation, and the parent is red, the green element of looking of parent is experienced the stimulation excitation time simultaneously, and brain will produce yellow sensation, and, the parent green continuous variation of looking plain excited ratio red along with the parent will produce orange or yellowish green sensation.If the parent is blue, the parent is green, the parent looks element and stimulated by indigo plant, green, red three kinds of coloured light equivalent to produce excitation time, just obtain the sensation of white for red three kinds.Be not difficult to find out that the reflected light of common white paper can make three kinds of pyramidal cells excited simultaneously for a long time, thus visual fatigue very easily caused, and then suppress colour vision function, reduction visual capacity, may cause myopia.Close red, the close green element of looking is experienced the stimulation excitement and green or yellow paper only make, thereby can prolong the time of visual fatigue.After visual fatigue took place, eye is long-time excessively to be regulated, and makes ophthalmic choroid hypovolemia, follows the string.Wall of eyeball also follows the string thereupon, the extraocular muscles oppression eyeball, and intraocular pressure raises relatively, is directed at the elongation of eyeball antero posterior axis, causes myopia.

In recent years, according to inventor's observation, cause the reason of myopia to be: 1. during the close eye transition, intraocular ciliary muscle continues to shrink, and can not get due laxly for a long time, causes the spasm of accommodation and a kind of near-sighted state that forms; 2. eyeball surface adheres to the flexible harmony of muscle and has been upset, and has increased the weight of the compressing to eyeball, forces eyeball elongated gradually in the course of time.

For this reason, the inventor thinks to life-time service eyes person, should change eye-using environment by watching different colors, forces ocular nerve constantly to move, and impels intraocular ciliary muscle to restore to the original state.

The present invention can have monochrome, double-colored or polychrome with the background color in one page (2), makes white, yellow, green cross occurrence, also can be from the superficial to the deep.The face a charge area coverage of album of paintings or calligraphy face (1) of described background color (2) is 40-100%.Being background color (2) can not cover around the pattern of the books for taking notes or keeping accounts page (1), literal, form, is the primary colors of paper.The described background color (2) that is assembled into the page (1) of books for taking notes or keeping accounts can be of the same colour in same, also can be polychrome, realizes replacing of color.

The typography of myopia preventing book of the present invention includes:

A. set type and make a plate;

B. modulate printing ink;

C. printing;

D. bind into book form.

The typography of described myopia preventing book is characterized in that print pass is at least once.The described page (1) but printing part screening, also whole screenings.Printing net-point line number is 24-80 line/cm.The coverage rate of Dot Area is between the 0-50%.

The invention has the beneficial effects as follows,

1. the paper that uses there is not special requirement.

2. background color can be eliminated floating light, the vignette of paper surface, thoroughly solves because the reflected light of paper suppresses the colour vision function, reduces visual capacity, causes visual fatigue, causes the problem of myopia.

3. reduced manufacturing cost.

Since in one page or one, can realize color alternately, change the eye-using environment of eye user, force ocular nerve constantly to move, impel intraocular ciliary muscle to restore to the original state.Pseudomyopia is had significant curative effect, and true myopia is no longer deepened.
