Description

Myopia preventing book

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.

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 student 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 reverberation 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 reverberation 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 psychological condition.These new books are thin have been solved really because the reverberation 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, system paper 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 in a large number on the other hand, a large amount of blank sheet of paper of normal use can not be used.

Summary of the invention:

The purpose of this utility model is to avoid the deficiencies in the prior art part and a kind of myopia preventing book is provided.

The purpose of this utility model 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, pseudo-myopia 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 cones on the human eye retina, contain three kinds of different visual pigments respectively among these three kinds of cones, 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 cones, produce photochemical reaction behind three kinds of pigment absorption light, cause nervous activity, reach nerve center through Beale's ganglion cells and gangliocyte, 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 reverberation of common white paper can make three kinds of cones 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 intraocular choroid hypovolemia, follows the string. and wall of eyeball also follows the string thereupon, the extraocular muscle oppression eyeball, 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 long-term use 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 utility model 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 beneficial effects of the utility model are,

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 reverberation 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 eye user's eye-using environment, force ocular nerve constantly to move, impel intraocular ciliary muscle to restore to the original state.Pseudo-myopia is had significant curative effect, and true myopia is no longer deepened.
