Description
The present invention relates to a kind of books of reading and writing usefulness, particularly can prevent to comprise books and the book that writes because of reading and writing the books of the myopia that causes.
Existing books mainly adopt blank sheet of paper to open printing.Blank sheet of paper is opened visible reflection of light stronger, and particularly the reflectivity to the light wave of different frequency is more even.Adopt blank sheet of paper to open the books of printing because reflection is strong, font contrast height, the visual fatigue and the kopiopia that cause are bigger.For this reason, the open CN1137980A of Chinese patent application has proposed a kind of asthenopic books of attempting to reduce.It is the so-called yellow paper printing of 550-610 nanometer that these books adopt the reflecting light wavelength.Its inventor thinks, because this paper can selectivity absorb light wave, only reflects the coloured light of specific frequency spectrum (wavelength 550-610 nanometer), can change visual environment, and elimination causes harmful environmental factor and prevents and treats myopia.But, the books that adopt this yellow paper to print, have the problem of following several respects: at first, under common illumination condition, only reflect the paper of specific frequency spectrum coloured light (for example 550-610 nanometer light wave), it makes relatively difficulty; Secondly, in the colour vision of human eye, the yellow that yellow, particularly purity are higher is to be easy to cause asthenopic color in all colours most, and it often caused strong eye to stimulate, and when display screen was regarded industry as, yellow was exactly clearly to be used as one of the background that should not use; Moreover with the adjusting physiology of human eye, narrower thorn laser wave frequency spectrum also can damage regulatory function, and the accuracy of reduce regulating increases the regulating error of looking when near, and regulating error just is only the immediate cause (rather than adjusting itself) that causes myopia; In addition, because three kinds of visual cells of human eye, its spectrum sensitivity peak wavelength is respectively 565,535 and 450 nanometers, and reflectance spectrum that should the yellow paper has been got rid of latter two peak value and near spectrum frequency range thereof, it is strong partially to cause looking the red blood cell reaction, and looking nearly regulating error when existing exactly, the speckle that is produced by the red wave band side of spectrum stimulates and has caused that the axis oculi growth that causes myopia quickens.Therefore, adopt this books control myopia, be difficult to produce a desired effect.
Purpose of the present invention provides a kind of visual environment can improve reading writing the time, the books of pre-myopia prevention.
Technical scheme of the present invention is, adopts its reflectance spectrum reflectance peak wavelength below 580 nanometers, and visible its reflectivity of light wave frequency range more than the wavelength of respective value is lower or be the books that the paper of valley is made, as the myopia prevention books.Respective value described here is meant the numerical value of reflectance peak place wavelength.Its reflection characteristic in the following light wave frequency range of wavelength 580 nanometers of the paper of these books can be a single peak type, for example gets the reflectivity peak wavelength between the 540-560 nanometer, for example about 550 nanometers, perhaps between the 520-540 nanometer, for example about 530 nanometers, perhaps between the 490-550 nanometer; Or bimodal pattern, for example Fan She two peak wavelengths are respectively between the 530-550 nanometer and between the 450-480 nanometer, or about 530 and 550 nanometers, or about 535 and 450 nanometers; Or the multimodal type, in 580 nanometers to form a plurality of reflection peaks zone down to the visible region between 400 nanometers; Or flatbed, promptly in certain wavelength period of the visible region below 580 nanometers, its reflectivity is all than higher and evenly to constitute spatial distribution be broad relatively platform pattern curve or near the low gradient domatic or the irregular shape curve of platform shape.In fact, above-mentioned multimodal type of the present invention also can be regarded a kind of of flatbed as, and promptly flatbed comprises the multimodal type.Accordingly, at above-mentioned peak wavelength (for example 550 nanometers) in addition, the particularly ruddiness of long wave and closely ruddiness (for example more than 580 nanometers) spectrum side, its reflectivity is lower, constitutes valley.For example, constitute the reflectivity low ebb in 610-650 (or 700) nanometers.That is to say, adopt longer wavelength spectrum (for example more than 580 nanometers, or more than 560 nanometers, perhaps more than the 550 nanometers) paper that reflectivity is lower is made into myopia prevention books of the present invention.
According to the colour vision perception of eye, the light of simple 550-580 nanometer mainly causes yellow consciousness, and the light of 490-540 nanometer mainly causes green consciousness, and the light of 450-480 nanometer mainly causes blue consciousness.According to the reaction mechanism of losing lustre that is used to describe object color, the paper with above-mentioned spectral reflection characteristic can be rendered as the color that primary colours are mainly cyan, green, blueness or color such as yellowish green.Because color belongs to psychophysical quantity, though can reflect the optical characteristics of paper roughly, inconvenience accurately quantitatively, therefore, is described the optical characteristics of paper comparatively subtly, and is comparatively suitable as quantitative basis with its spectral reflectivity.The spectral reflectivity characteristic of paper also is the key factor of visual environment when constituting read-write.Owing to looking when near, the light wave of the long-wave band side of the defocused image of the eye that produces because of regulating error just is formed with promotion to myopia, the light wave of short wavelength side can not promote myopia progression, so, books of the present invention are because the light reflectivity of its paper is higher than the long-wavelength region more than 580 nanometers at the shorter wavelength frequency spectrum place below 580 nanometers, thereby have reduced the facilitation of long wavelength side light wave to myopia relatively; The long wave spectral reflectivity is low more, and this effect is good more.There is aberration in the dioptric system of human eye, can reach near 3 diopter levels at visible spectrum two ends aberration, and wavelength is short more, and light refraction within the eye is strong more.Because its paper of books of the present invention is higher to the short-wavelength light reflectivity, reflectance spectrum is concentrated, and has not only reduced aberration, reduced the stimulation of the video speckle that causes because of aberration to eye, and reduced the regulatory demand of looking nearly of eye, thus can reduce the adjusting of eye, reduce the kopiopia degree.For example, be that 535 nanometers are calculated with the reflectance spectrum peak value wavelength of green paper, white or aforesaid myopic-preventing yellow paper can reduce and regulate and the about 0.5-0.6 diopter of dioptric demand.Therefore, with regard to reducing regulatory demand, its spectral reflectivity peak wavelength numerical value of the used paper of books of the present invention is low more good more, for example, gets below aforesaid 580 nanometers, perhaps below 550 nanometers, even below 540 nanometers merely.But generally should not too much be lower than about sensitivity spectrum peak wavelength 535 nanometers of green quick awl cell, in order to avoid make the paper surface lightness low excessively.With regard to reducing aberration, the Wavelength distribution of reflectance peak is narrow more, and aberration is more little, if adopt the paper of narrower unimodal or flatbed reflectivity, can reduce the speckle optical stimulation that aberration causes to large extent.But aberration is more little, and total reflected light can be low more, and spectral power distribution is narrow more, and luminous energy is crossed low or spectrum when too narrow, can damage the regulatory function of eye.Therefore, to the relatively poor relatively user of regulatory function, adopt the paper of the spectral reflection characteristic with bimodal pattern, multimodal type or flatbed of spectrum broad, the books of making as cyan, yellow green paper, can avoid influencing regulatory function preferably, and suitably keep the surperficial lightness of books.Because green is represented plant and nature, can make the people relaxed and joyful, the books that use green paper to make also help relaxation of tension.The relative lightness of yellow green or cyan paper is higher, is suitable for darker environment or uses in the occasion that the contrast of printing or the prospect of handwriting and background may reduce.
IES's suggestion, the prospect of industry is regarded in maximum being suitable for as and the luminous reflectance rate of background is 3: 1.Therefore, can be with reference to this numerical value, in conjunction with the light reflectivity of the ink marks of used printing or writing words, determine the concrete spectral reflectance rate score of the used paper of books of the present invention thereon.
For reducing the chromatic adaptation or the after image phenomenon that may occur, can adopt the books of making in the alternate mode of paper of above-mentioned different light reflectivities (different colours) as myopia prevention books of the present invention, or the books that adopt different colours (or different spectral reflectivity) alternate paper on a piece of paper to make.For example, adopt yellowish green, green, the cyan paper is alternate or assorted between the books made, or adopt blue or green, green, blue assorted between the books of paper making on it, as myopia prevention books of the present invention.
Because the individual has certain color preference, one of embodiment that the present invention is best adopts cyan, yellowish green, green different colours to mix the books that alternate paper is made, or the paper of above-mentioned different colours mixes the books of alternate making as myopia prevention books of the present invention.In addition, in such books, be mingled with on a small quantity that some blank sheet of paper are opened or the paper of other color, can't obviously influence the myopia prevention effect of books of the present invention, but can increase interest or decorative effect.
As one of of the present invention best embodiment of monochromatic books, adopt its spectral reflectivity to be platform peak value type between left and right and outside this wavelength region may, all to be the books that the paper of low ebb type is made in wavelength 480-550 nanometer, provide at aspects such as aberration, adjusting, lightnesses relatively perfectly association schemes, had the effect of pre-myopia prevention preferably.For example, can be used in the 480-550 nano spectral scope average reflectance at 60-80%, and more than 580 nanometers and the spectral reflectivity below 460 nanometers be lower than the books that 40% or 20% paper is made, as myopia prevention books of the present invention.
The reflectance peak wavelength that is noted that the paper described in the present invention can't have a strong impact on the effect of the pre-myopia prevention of these books concerning colony uses in the change of numerical value in more among a small circle, for example, depart from 5 nanometers from 580 nanometers, even 10 nanometers, actual influence is very limited.
Yet in order to be effective, the peak value of the described reflectivity of the paper of books of the present invention and the difference of valley are the bigger the better, and preferably differ more than one times, and for example reflectance peak reaches at 80% o'clock, and valley is preferably lower than 40%, or 20%, even below 10%.
Myopia prevention books of the present invention, the books of the yellow paper of the myopia prevention of comparison of aforementioned, because and the reflecting light frequency spectrum that does not require used paper is defined in certain narrow frequency range, and just require the reflectivity of paper higher in specific light wave frequency spectrum, in other frequency ranges, particularly the long wave frequency range is lower, thereby manufactures than being easier to.And make and look nearly regulatory demand reduction, color is softer, is difficult for causing kopiopia and visual fatigue, is eliminating as far as possible under the condition of harmful light in addition, and reverberation frequency spectrum broad is less to the influence of emmetropia regulatory function.
Myopia prevention books of the present invention, can be used as the didactic works book, for example, as the textbook and the book that writes, use for looking the more student of early work industry, particularly use, replace present widely used white books, can receive best myopia prevention effect for being in this easiest student that the age bracket of myopia takes place of 10-20 year.
