Description

A kind of processing method of myopia prevention font

Technical field

The present invention relates to pre-myopic-preventing method, specifically refer to a kind of method font being processed and realizing correct reading posture。

Background technology

Students of nation physical health investigation latest data shows, China pupil myopia sickness rate is 22.78%, and middle school student are 55.22%, and high school student is 70.34%。There is a part investigation report to claim, domestic reached ten thousand people more than 30 because of high myopia blinding person。And some specialty has very high requirement (army, hospital, manufacture of high precision instrument etc.) army then to concern defense force for vision, thus, myopia is a very great problem, and is not merely teen-age physiological problem。For the rectification of posture, this stage of growth promoter, the raising of the learning efficiency, and cause that some nervous system diseasies in old age have preventive effect, and be not only these one side of eyes。

If reading posture is incorrect, may result in rachiocamposis, or bow-backed。The hunch teenager for growing is not a minor matter。Huangdi's Internal Classics cloud: " the sitting injury of the bone, impairment caused by overstrain gas of a specified duration ... " that is long-time nonstandard volt seat can damage skeleton, forms physical abnormality。Teenager deficiency of primordial QI, skeleton is unreal, and sclerotin is partially soft, it is easy to bow-backed deformation。The long-time abnormal bending of spinal column then can cause being on tenterhooks, dynamic, inappetence absent minded, many time, if being corrected not in time, treating, child's hunch will be caused in the course of time。Long-term letting alone is developed, and can affect cardio-pulmonary function and the normal development of other functions of health, and therefore active prevention hunchback deformity is highly important。Adolescence is particularly important。

The incidence rate of current China students in middle and primary schools' scoliosis is obvious ascendant trend。But scoliosis not yet causes the great attention of family, school and society so far。Beijing rehabilitation medicine can be pointed out in nearest a report, and myopia, scoliosis and psychological problems have constituted the Three Obstacles that juvenile healthy is grown, and survey data shows that this three big problem is just presenting degradating trend。Simultaneously another part of investigation report show: in the thousands of specialty of universities of China, have the specialty of 42% to myopia, bow-backed, figure not just etc. student limit and enter oneself for the examination。The obstacle of the problems such as the scoliosis that this means to be caused by bad sitting walking posture, hunchback, myopia not still growth promoter, more directly influences the employment of entering a higher school that teenager is following。Slight scoliosis is usually not significantly uncomfortable, and outward appearance is not easy to see obvious physical disfigurement。But serious scoliosis can affect growth promoter, makes physical disfigurement, as at one " rib peak " of breast back part protuberance, being called " the razor back of the body "。Along with thoracic deformity, the function of internal organs and activity being made to be affected and limit, slightly motion arises that nervous, out of breath, uncomfortable in chest, cyanotic lips, and has the symptom such as loss of appetite, dyspepsia。

In order to correct and remind reading posture and the reading distance of students in middle and primary schools, existing market has the school bag of prompting function, pen, desk, desk lamp etc., by above-mentioned external articles for use, it is possible to reach certain effect。But without above-mentioned external articles for use, it is difficult to accomplish pre-myopic-preventing possibility in fact。But above-mentioned instrument is the effect serving mandatory prompting mostly, the one being namely external is informed and points out, rather than self finds fault。

Also being do not have to adhere to correct reading posture and reading distance when people read books, magazine, this also results in adult also can occur the possibility of myopia。

Progress along with digital product technology, the reading method of existing people has been not limited only to books, can also be read by the screen of electronic product, but the restriction due to screen size, generally require and lean on to obtain closer ability easy-to-read, but electronic product all has radiation, lean on more near, radiate more severe。

Summary of the invention

It is an object of the invention to provide a kind of processing method keeping reading the myopia prevention font of attitude and distance when people can be helped at read books, periodical, teaching material etc. and by showing people's screen reading electronic book。The inventive method process after font be allow reader oneself subjectivity recognize that oneself reading posture is incorrect, not as external a kind of prompting。

The present invention can be achieved through the following technical solutions:

The invention discloses the processing method of a kind of myopia prevention font, the method includes the word to different font size sizes or letter processes, and creates the character library of corresponding font size, and the processing procedure that word or letter is concrete is as follows:

(1) the little square that the wide cut-out for 0.2mm processes or digs out length of side 0.2mm is carried out for the stroke of word that the stroke width of writing or person's handwriting is 0.3mm～0.5mm or letter, make that stroke has multiple 0.2mm space or space；

(2) positions such as curved, the hook of stroke part of word that the stroke width of writing or person's handwriting is 0.3mm～0.5mm or letter are not dealt with；

(3) the little square that the wide cut-out for 0.1mm processes or digs out length of side 0.1mm is carried out for the stroke of word that the stroke width of writing or person's handwriting is more than 0.6mm or letter, make that stroke has multiple 0.1mm space or space；

(4) positions such as curved, the hook of stroke part of word that the stroke width of writing or person's handwriting is more than 0.6mm or letter are not dealt with；

(5) stroke for word that the stroke width of writing or person's handwriting is 0.1～0.2mm or letter does not deal with。

The font size of the word described in above-mentioned steps or letter is No. three or No. four or little four or No. five words。

Above-mentioned steps processes just for the straight part in stroke, for because of the form of different fonts make stroke with rise angle, rise curved, rise hook, starting point part do not deal with。Why do not process and be to ensure that font can be the same with normal font (under namely correct reading posture) under normal visual field。

Described space can be left a blank or fill different colors or is the square frame with frame。

The processing method of myopia prevention font of the present invention is by the process to font stroke, when the incorrect reading posture of people and reading distance, just can see the difference in font, namely the word seen has slight obscuring, or it is unintelligible, clearly, thus adjusting posture and distance, till can't see difference。The processing method of myopia prevention font of the present invention is applicable to the font of any size。As long as no matter great font is taked below 0.6mm and cutting methods different above。Can reach to correct posture, it is prevented that the purpose of myopia。

Detailed description of the invention

For the ease of the understanding of those skilled in the art, below in conjunction with specific embodiment, the principle of the invention is described in further detail。

The invention discloses the processing method of a kind of myopia prevention font, the method includes the word to different font size sizes or letter processes, and creates the character library of corresponding font size, and the concrete processing procedure of word or letter is as follows:

(1) the little square that the wide cut-out for 0.2mm processes or digs out length of side 0.2mm in the middle of stroke is carried out for the stroke of word that the stroke width of writing or person's handwriting is 0.3mm～0.5mm or letter; make that stroke has multiple 0.2mm space or space; i.e. every cut-out separated by a distance or dig out blank in stroke, if stroke width is just cutting off every 0.2mm or digging out the little square of 0.2mm of 0.3mm；

(3) the little square that the wide cut-out for 0.1mm processes or digs out length of side 0.1mm in the middle of stroke is carried out for the stroke of word that the stroke width of writing or person's handwriting is more than 0.6mm or letter, make that stroke has multiple 0.1mm space or space；

(5) stroke for word that the stroke width of writing or person's handwriting is 0.1～0.2mm or letter does not deal with。Desirable effect is not had because having processed。

Above-mentioned steps processes just for the straight part in stroke, for because of the form of different fonts make stroke with rise angle, rise curved, rise hook, starting point part do not deal with。

As shown in Figure 1, Chinese " doing " word, its stroke width is 0.3mm～0.5mm, and the strokes that its two horizontal strokes one are perpendicular carry out the cut-out of 0.2mm respectively, namely adopting 0.2mm interval 1 that the stroke that two horizontal is perpendicular is divided into some sections, different colors can be left a blank or fill in interval 1。

As shown in Figure 2, English " Z " word, its stroke width is 0.3mm～0.5mm, and two oblique lines and horizontal line that form its stroke carry out the cut-out of 0.2mm, namely adopting 0.2mm interval 1 that the stroke that two horizontal is perpendicular is divided into some sections, different colors can be left a blank or fill in interval 1。

Principles of the invention is according to being: first, human eye has resolution。Namely, when watching object, can clearly see resolution corresponding to field of view clearly is 2169X1213。During viewing object, can clearly see eyes corresponding to field of view [visual angle] clearly and be about 35 ° (transverse directions) X20 ° (longitudinal direction)。Human eye is in intermediate light simultaneously, and [resolving power (d)] of medium-contrast is 0.2mm, and corresponding [optimum distance (L)] is 0.688m。Wherein d and L meets tg (θ/2)=d/2L, θ is [resolution angle]。Computational methods: the ground that is modeled as that visual field is approximate is rectangular positive vertebral body, wherein the height of vertebral body is 0.688m, θ 1=35 ° (horizontal view angle), θ 2=20 ° (vertical angle of view) are with 0.0002m for a point, it is possible to learn the resolution that ground rectangle is 2169X1213。

And in the font revised, it is ensured that each word all has the gap that distance is 0.2mm。And the reading distance of the best for this distance of 30-35cm(time, the eyeball muscle of human eye need not anxiety, be in the state loosened, so, also just it is not easy myopia, simultaneously in order to keep this distance, the posture of reader needs to adjust, and has simultaneously worked as the effect correcting posture。), when this distance, human eye is to differentiate the point (distance is 0.2mm) that diameter is 0.4mm。Any difference (the size color of font etc. and original striking resemblances) is not had with usually reading when ensure that reading。Eyes will not be damaged。But contrast can be slightly decreased, need when printing with more dark ink。When people reads when less than 30cm, human eye will can tell foregoing some mark, namely serve suggesting effect in time seeing a some mark, it is ensured that when reading, people are necessarily to ensure that reading distance is outside 30cm, ensure loosening of eyeball muscle, improve the quality of reading。

The above, be only presently preferred embodiments of the present invention, and the present invention not does any pro forma restriction；But the those of ordinary skill of all industry all the above and implement the present invention swimmingly；But, all those skilled in the art without departing within the scope of technical solution of the present invention, available disclosed above technology contents and make a little change, modify and the equivalent variations of differentiation, be the Equivalent embodiments of the present invention；Meanwhile, all change of any equivalent variations, modification and differentiation etc. above example made according to the substantial technological of the present invention, all still fall within the protection domain of technical scheme。
