Abstract
The utility model relates to a color health-care note book for preventing myopia which belongs to the technical field of stationer goods. The health-care note book is rectangular and is printed by straw yellow paper. The length, the width and the thickness of the health-care note book respectively are 1=10-24 cm, m=6-16 cm and h=0.15-0.4 cm. The color health-care note book for preventing myopia is suitable to be used for books of schools and homework books of students. The color health-care note book for preventing myopia is printed by straw yellow paper. The reflectance spectrum of the straw yellow paper is the color light, the wave length of which is 550-650 nanometers. The color light of a certain spectrum is reflected by the light wave selective absorption function of the straw yellow paper. The harmful environmental factor is eliminated. The color health-care paper has smooth surface and good water resistance and oil resistance. The physical strength and the surface strength totally reach the standard of the writing paper. The color health-care note book for preventing myopia can prevent and cure the myopia of a user.
Description
Technical field
The utility model relates to a kind of colored myopia prevention health care book, belongs to the cultural goods technical field.
Background technology
Traditional write or print books or operation is thin, all adopt white paper to print.The book of printing with white paper is thin, is characterized in that brightness is strong.Because of white paper reflection be white full range light, in different visual environments, visual capacity is different with degree of fatigue.
The student mainly is reading, writes with the eye mode, and eyes utilize the colourity of paper and font and luminance contrast to feel the font shape.Colourity is directly proportional with catoptrical intensity, and brightness is directly proportional with catoptrical intensity.People often only notice the strong advantage of brightness that white light causes, have but ignored the shortcoming that colourity is weak, visual fatigue is big that white light causes.Present book thin paper is opened more and more pure whiter smooth, almost keep original frequency spectrum and intensity reflection to go in eyes white illumination light, thereby become a main cause of myopia, this is because white light can suppress the normal performance of colour vision function, can only cause initial colour vision, reduce visual capacity.White light intensity maximum sees that in fact written word is in high light and stimulates down, in the high-high brightness contrast, can cause the strongest visual fatigue, sighting distance length no matter, ciliary muscle all is in the excess shrinkage state, make focal length reach, the dimness of vision, cause hypometropia.
Summary of the invention
The purpose of this utility model is to propose a kind of colored myopia prevention health care book, with specific faint yellow paper printing, is used for the homework book that teach book and the student of school write, and is beneficial to student's eye health.
The colored myopia prevention health care book that the utility model proposes, this health care book is the cuboid of being made up of faint yellow paper, length and width, thick l=10～24cm, m=6～16cm, the h=0.15～0.4cm of being respectively of health care book.
The colored myopia prevention health care book that the utility model proposes is applicable to the homework book that teach book and the student of school write, and the making of colored myopia prevention health care book adopts faint yellow paper to print, and the reflectance spectrum of this faint yellow paper is the coloured light of wavelength 550-650 nanometer.The utility model utilizes the selective absorption of faint yellow paper to light wave, only reflects the coloured light of specific frequency spectrum, eliminates to cause harmful environmental factor.This colored vision strengthening paper does not attractive in appearancely lose bright-colouredly again, does not hinder eyes, surface smoothing, and water-fast, oil resistivity good, physical strength and surface strength all obtain the standard of writing paper, and can prevent and treat user's hypometropia.
Description of drawings
Fig. 1 is the structural representation of the colored myopia prevention health care book that the utility model proposes.
Fig. 2 is the front view of an embodiment of the present utility model.
Among Fig. 1, l is the length of health care book, and m is the width of health care book, and h is the thickness of health care book.
The specific embodiment
Among the embodiment of the colored myopia prevention health care book that the utility model proposes, its length l can be 20cm, and width m can be 12cm, and thickness h can be 0.2cm.
The book and be mainly used in the homework book that the student writes of teaching that pre-myopia prevention colorful health-care is thin to be applicable to that school uses.Replace original white paper to print with faint yellow paper, the reflectance spectrum of this faint yellow paper is the coloured light of wavelength 550-650 nanometer, also can mix an amount of faint yellow dyestuff when top sizing in sizing material, and dye dosage is decided according to paper pulp or paper quality.Light wave spectrum with the finished product reflection is that wavelength 550-650 nanometer coloured light is as the criterion.
But also dialogue coloured paper Zhang Jinhang red ink paste used for seals.Prescription for do not have with the offset printing of 10-21 resin China ink with 915 transparent water down to deceive mix as stamp-pad ink with 1: 1 ratio.Routine techniques is adopted in the printing of health care book.Can know that by experiment the photochromic spectrum of yellowish coloured 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 reached simultaneously to be given full play to, and make color soft attractive in appearance, reduce of the stimulation of strong reflection light to eyes, alleviate the user reading, when writing visual fatigue and to the injury of eyes, reach pre-myopia prevention, colored strong purpose of looking.
