Abstract

The present invention relates to a technology of paper which is bound into books and thin books and provides reflecting color light for efficiently keeping the normal vision of human eyes. The technology mainly overcomes the defects that the existing paper hardly comprehensively adapts to the requirements for eye using environment, reading efficiency, etc. The range of the spectral wavelength of a reflection light color card for book paper provided by the present invention is from 615 nm to 660 nm (color light). The technology application enhances the eye using efficiency and reduces the degree of fatigue of the eyes to the minimum.

Description

Paper for making eye protecting book

What technical field the present invention relates to is the paper technology that is used to bind into book, thin volume, thereby in particular changes the new technology that its paper reflection coloured light is safeguarded twenty-twenty vision to greatest extent according to visual theory.

Background technology is present, there have been many technical staff to begin to recognize the thin serious consequence that is produced of existing " in black and white " book, these blank sheet of paper printed matters for, special for preschool child and teenager in being in body development, it is to cause eyesight to descend and even the main odjective cause of pathological consequences." in black and white " adopted the strongest luminance contrast mode to remove to satisfy people's initial stage, temporary transient visual sense feeling, just because of the surplus printed matter technology of whole white background has been ignored the sensing capability that human eye stimulates colour vision, make colour vision be subjected to severe inhibition, cause the induction of colour vision and light sensation to coordinate jointly to play a role, thereby do not reach the vision purpose of effectively and like a cork looking thing, distinguishing thing.In addition, human eye is in the environment of white full range light high strength reflection for a long time, and pupil is forced to be in deflated state, and sphincter, ciliary muscle shrink, cause function fatigue for a long time.Here it is main immanent cause that why teenager's poor sight incidence raises gradually.

Present situation for a change, Chinese patent: the patent No. is 95111654.1, name is called the patented technology of " a kind of myopia prevention book is thin ", having proposed with the reflecting spectrum wavelength is that the paper of 550-610nm coloured light is as book Bao Yongzhi.Another Chinese patent application technology: number of patent application is 9811078.5, name is called " vision-protection book with paper and the opaquing fluid that is used with it " technology, and the green light that has further proposed colour atla wave spectrum scope and be 540-570nm on the basis of a last patent reflects the book Bao Yongzhi of coloured light.The proposition of these prior arts with " though the thin manufacturing technology of ~ book has epoch making significance in black and white; these prior aries have been improved eye-using environment to a certain extent; also only emphasized the suitable environment of colour vision from another angle, and in the inhibition that realizes matter more with kopiopia, aspect the technology solutions such as raising of the efficient of requiring mental skill, very be short of.

The technical scheme that summary of the invention patent application technology of the present invention is proposed, the paper that its key is to solve existing specific background color as book, thin volume is difficult to adapt to eye-using environment comprehensively and requires and aspect requirement such as reading efficiency, change the raising defective that prior art puts undue emphasis on the colour vision ability, make each factor of eye-using environment be able to cooperation, realize the true purpose of eyeshield health.The major technique characteristics of technical scheme proposed by the invention are: what this book approached goods is the coloured light of 615-660nm with paper employing reverberation colour atla spectral wavelength scope.

In above-mentioned overall technical architecture, the degree of saturation of the coloured light of its described wavelength is: the primary colors red mixed volume is 23-45%, and the yellow mixed volume of primary colours is 23-40%, and all the other are for sneaking into white light.

Scientific research shows, aberration depends on the difference of light particle oscillation speed, the ruddiness colour system: the number of oscillation is approximately TFlops each seconds 400, the purple light colour system: the number of oscillation is near 800 TFlops, other visible light colour system is distributed between this two colour system, wherein orange colour is 530 TFlops, green is 600 TFlops, blueness is 650 TFlops, indigo is 700 TFlops, the visible light series of going forward one by one as can be known by red colour system to violet, its number of oscillation has increased nearly 400 TFlops, and the quickening of the number of oscillation, human eye is stimulated degree and produces the also increase thereupon of tired degree, so it is minimum that red light can make the degree of fatigue of eyes reduce to, test comparison data by " red and yellow; the test report of the anti-visual fatigue effect of green books " show: read after 60 minutes, experimenter's 92%, 41%, 22% contrast vision all descends to some extent, but through relatively showing, it is minimum to read its eyesight fall of red books, yellow is taken second place, green books once more, comparison threshold value with great visual angle by the reader, middle visual angle comparison threshold value all increases to some extent, and it is red, the yellow amplitude that increases is less than green books, and test structure illustrates that the anti-fatigue ability of red books is higher than or slightly high green and yellow books.Secondly, human eye is finished by three kinds of cones' cooperations of red, green, blue on the retina the perception of color, the light wave of different wave length stimulates, can cause the decomposition of three kinds of photopigment different proportions respectively, thereby produce the impulsion of different colour visions, tell different colors, if only emphasize a certain or two kinds of primary colours, also difficulty makes most of cones's fellowship colour visions inductions, reaches good vision response.The macula lutea of foveal region of retina is the sensitizing range of vision, and the cones is only contained at the macula lutea center.And, by central fovea of macula to its periphery, its cones reduces gradually, rhabdocyte increases gradually, cone causes the vision excitement easily to ruddiness, and rhabdocyte is insensitive to red end, so in suitable red reflex light atmosphere, people's notice is more concentrated, show that with experiment reading efficiency can improve 20% (please refer to " the contrast survey report of the reading learning ability of ruddiness books and yellow iron of fine quality books ") in the ruddiness atmosphere.

By above red books, yellow books and green books the principle analysis and the experimental data of reading personnel's visual impact proved, the colour atla spectral range be the red reflex light of 615-660nm to eye-using environment that human eye vision was suitable for, to improve the superiority of aspects such as reading efficiency simultaneously more obvious, and can further reduce the degree of fatigue of human eye.

The specific embodiment

The book of the technology of the present invention is thin can to adopt the mode of former paper pulp colouring to make with paper; its specific embodiment can select to use the dyestuff of reduction bright red RB or Vat Orange 2 RT to paint as paper pulp; also can also select reverberation frequency spectrum other orchil in the 615-660nm scope for use; its dye dosage accounts between the 0.04-0.16% of paper pulp weight; specifically select for use ratio to decide according to pulp brightness; its pulp brightness preferably is controlled between 71-80 °; because reduce the thin smoothness of book with paper; can make it form diffuse reflection; what make human eye acceptance is gentle stimulation of closing light, helps the protection of eyes.This book Bao Yongzhi, within the scope of its described reverberation spectral wavelength, and its degree of saturation to should be the primary colors red mixed volume be 23-45%, the mixed volume of primary colours Huang is 23-40%, all the other are for sneaking into white light.
