Abstract
The utility model relates to a colored myopia-proof health-care notebook which belongs to the stationers goods technical field. The health-care note book is a rectangle and is printed by the straw yellow paper. The length, the width and the thickness of the health-care note book respectively are l=24-28 cm, m=16-20 cm and h=0.4-0.5 cm. The colored myopia-proof health-care notebook is suitable to be used for the books of the school and the homework books of the student. The colored myopia-proof health-care notebook is printed by the straw yellow paper. The reflectance spectrum of the straw yellow paper is the color light whose wave length is 470-550 nanometers. The certain spectral color light is reflected by the selective absorption function of the straw yellow paper to the light wave and the environmental factor which causes harm is eliminated. The colored health-care paper has beautiful appearance and does not lose brilliance or hurt eyes and 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 colored myopia-proof health-care notebook provides a safe and comfortable visual environment for the user to prevent and cure the myopia of the 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 is cuboid, is printed length and width, thick 1=24～28cm, m=16～20cm, the h=0.4～0.5cm of being respectively of health care book by faint yellow paper.
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 470-550 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, provide the visual environment of safety and comfort to the user, with the control 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 26cm, and width m can be 18cm, and thickness h can be 0.4cm.
The colored strong book and be mainly used in the homework book that the student writes of teaching that is applicable to that school uses of looking thin of pre-myopia prevention.Replace original white paper to print with faint yellow paper, the reflectance spectrum of this faint yellow paper is the coloured light of wavelength 470-550 nanometer, used faint yellow be that the big people's paper industry of Inner Mongol Wuyuan County company produces, also can mix an amount of faint yellow dyestuff when top sizing in sizing material, dye dosage is decided according to paper pulp or paper quality.Light wave spectrum with the finished product reflection is that wavelength 470-550 nanometer coloured light is as the criterion.
Used faint yellow paper is produced by the big people's wealth of Inner Mongol Wuyuan County paper industry company.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.The printing coloured silk routine techniques of books.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.
