Abstract

The present invention discloses a myopia prevention book printed by particular yellow paper, which is characterized in that the book is printed with the yellow paper, and the reflecting light wave spectrum of the yellow paper is color light of which the wavelength is 550-610 nm. The present invention only reflects color light with specific spectrum by utilizing the selective absorption which the yellow paper performs on the light wave to eliminate harmful environmental factors in order to create a safe and comfortable visual environment so as to prevent and cure myopia.

Description

A kind of myopic-preventing books
The present invention relates to a kind of books of the usefulness of imparting knowledge to students, is the yellow paper of a kind of usefulness and the myopic-preventing books printed specifically.
Existing books all adopt white paper to print, and with the books of white paper printing, its characteristics are that brightness is strong, are white full range light because blank sheet of paper opens reflection.In different visual environments, visual capacity is different with degree of fatigue, and the student's mainly is to see that written word, eyes are to utilize the colourity of paper and font and luminance contrast to feel the font shape with the eye mode.Colourity is directly proportional with catoptrical purity, and brightness is directly proportional with catoptrical intensity.People often only notice the strongest advantage of brightness that white light causes, it is the most weak but to have ignored the colourity that white light causes, the shortcoming of visual fatigue maximum.Snow blindness is exactly that typical visual environment pollution causes harmful phenomenon.The way of unilateral enhancing daylighting brightness can increase visual fatigue when improving visual brightness, the variation of intensity of illumination can not alleviate the vision burden.Present books paper is more and more pure whiter smooth, can almost keep original frequency spectrum and intensity reflection in eyes, to go white illumination light, become near-sighted inducement: white light can suppress the normal performance of colour vision function, can only cause initial colour vision, has reduced visual capacity; White light intensity maximum is seen written word is actually and is in high light and stimulates down, when obtaining the high-high brightness contrast, can cause the strongest visual fatigue, sighting distance length no matter, and ciliary muscle all is in the excess shrinkage state, makes the focus point reach, and video is fuzzy.So visual environment is very big to bathomorphic formation influence.
The object of the present invention is to provide a kind of myopic-preventing books, prevent and treat myopia from changing visual environment.
To achieve these goals, the present invention adopts following technical scheme: a kind of myopic-preventing books is characterized in that: the making of books adopts yellow paper to print, and the reflecting light frequency spectrum of this yellow paper is the coloured light of wavelength 550-610 nanometer.
Good effect of the present invention is: change the color that the book thin paper is opened, utilize yellow paper that the selective absorption of light wave is only reflected the coloured light of specific frequency spectrum, eliminate causing harmful environmental factor, create the visual environment of safety and comfort.
Embodiment:
Books of the present invention mainly are the textbook and the exercise-books of teaching usefulness, replace original white paper to print with yellow paper, and the reflecting light frequency spectrum of this yellow paper is the coloured light of wavelength 550-610 nanometer.Used yellow paper can directly add an amount of weld as being that paper plant produces in paper pulp when carrying out internal sizing, also can mix an amount of weld when carrying out top sizing in sizing material.Dye dosage is decided according to paper pulp or paper quality.Light wave frequency spectrum with the finished paper reflection is that wavelength 550-610 nanometer coloured light is as the criterion.Used yellow paper is as being that books are printed factory and produced, but dialogue coloured paper Zhang Jinhang red ink paste used for seals is filled a prescription to blackly mixing as stamp-pad ink with 1: 1 ratio with 10-21 resin glue printing ink and 915 transparent watering down.Routine techniques is adopted in the printing of books, so do not explain.Can know that by experiment the sodium yellow frequency spectrum of yellow paper reflection of specific colourity is very little and be in the intermediate frequency optical range, can cause the strongest colour vision with the light wave of minimum and only be second to the brightness of white light slightly, colour vision, visual performance are not fully exerted simultaneously, can also make visual fatigue be relieved to minimum level.
