Introduction
(myopia) is the concept of vision, a vision for a distant object, and to see a close - up of symptoms (myopia) is the concept of vision, a vision for a distant object, and to see a close - up of symptoms . diopter to rest on the premise of a distant object in the retina cannot converge while forming the focal point in front of the retina, thereby causing visual deformation resulting in remote objects to appear blurred diopter to rest on the premise of a distant object in the retina cannot converge while forming the focal point in front of the retina, thereby causing visual deformation resulting in remote objects to appear blurred .
myopia and myopic are different concepts, myopia is far visual acuity, near vision is normal phenomenon of myopia; myopia diopter is a concept, a sort of myopia of the eye to myopia and myopic are different concepts, myopia is far visual acuity, near vision is normal phenomenon of myopia; myopia diopter is a concept, a sort of myopia of the eye to . dioptrics diagnosis subject, myopia is necessarily myopia,But not necessarily myopia short - sightedness dioptrics diagnosis subject, myopia is necessarily myopia,But not necessarily myopia short - sightedness .

The Cause And Prevention Of Myopia
- - known by the myopia can be roughly divided into the following several reasons of vision, a vision of protection should be based on different causes and take preventive measures.
Daily Life
1. the environment ray brightness for everyday life in learning and as a result of the work of vision, is the most efficient way in eye care because in most cases, visual loss and poor lighting (too dark, too bright) related to the film, in particular the strength of great learning, work and life in the environment ray brightness (illuminance) is not appropriate in many time because in most cases, visual loss and poor lighting (too dark, too bright) related to the film, in particular the strength of great learning, work and life in the environment ray brightness (illuminance) is not appropriate in many time .
low lighting, and sometimes too much light low lighting, and sometimes too much light . although, on the international and Chinese are different for the different occasions of light illuminance are all standard, but for ordinary people, which are responsible for healthy eyesight, with the help of a not - so - direct although, on the international and Chinese are different for the different occasions of light illuminance are all standard, but for ordinary people, which are responsible for healthy eyesight, with the help of a not - so - direct .
Usually, light is not appropriate to have three reasons:First, the environment inside of the light itself is not suitable (excessively bright / dark), a body posture (sitting posture) as head or incorrect will be blocked by the light, allowing suitable to direct the light to the target area is darker; the third is the ambient light brightness quickly changes (e.g. every morning / night time, cloudy / rainy) In addition, different application scenarios of the illumination according to the same is less true, but, even if the luminance is the same as that of the human eye to different light sources (such as natural light and the lights in the drawing) of the feeling isn't quite what In addition, different application scenarios of the illumination according to the same is less true, but, even if the luminance is the same as that of the human eye to different light sources (such as natural light and the lights in the drawing) of the feeling isn't quite what .
Therefore, ordinary people in everyday learning,Living and working in really not easy to determine whether the luminance is of course suitable Therefore, ordinary people in everyday learning,Living and working in really not easy to determine whether the luminance is of course suitable . professional equipment can detect light and brightness, and high measurement precision, but only the measurement of light illuminance, without informing the measured illuminance of the light means, and which is suitable for application scenarios, and are thus more suited to professionals professional equipment can detect light and brightness, and high measurement precision, but only the measurement of light illuminance, without informing the measured illuminance of the light means, and which is suitable for application scenarios, and are thus more suited to professionals .
relatively, some photometric eye protecting pen on a light feeling of complexity, in a variety of different use and different eye patterns of the light source, the measured light intensity data, according to national standard 6, the conversion is easy to understand, practical indication and alarm information (such as too dark, darker, as appropriate, the brights,too bright, etc.), let the common people in learning, you can be very conveniently and improve lighting condition, so as to protect eyesight. The long - term, short - distance use of eyes for the majority of the student's vision is not a pathological, but her eyes mediation function of hypofunction in poor ambient light for a long period of time, near - eye, decreased visual acuity, myopia of the important reasons for in poor ambient light for a long period of time, near - eye, decreased visual acuity, myopia of the important reasons for .
eye accommodation is very strong, when the distance between the eye and books for 7 - 10 cm, was still able to see objects clearly, but if this distance is often read, write, and will make the eyes of abnormal tension, and therefore, it is possible to form the inflection (accommodative myopia), eye accommodation is very strong, when the distance between the eye and books for 7 - 10 cm, was still able to see objects clearly, but if this distance is often read, write, and will make the eyes of abnormal tension, and therefore, it is possible to form the inflection (accommodative myopia),. so called pseudomyopia if long - term over - shooting, and the ciliary muscle is not flexible, since the latter is caused by excessive convergence is all the action, the eye muscles put pressure on the eye, increased intraocular pressure, intraocular tissue filled with blood, plus the teenagers the delicate tissue of the eye, the eye wall is pressed gradually extends to ocular anteroposterior axis becomes longer and exceeds the normal form of axial myopia, true myopia so called pseudomyopia if long - term over - shooting, and the ciliary muscle is not flexible, since the latter is caused by excessive convergence is all the action, the eye muscles put pressure on the eye, increased intraocular pressure, intraocular tissue filled with blood, plus the teenagers the delicate tissue of the eye, the eye wall is pressed gradually extends to ocular anteroposterior axis becomes longer and exceeds the normal form of axial myopia, true myopia .
normal reading distance is 30 - 35 cm normal reading distance is 30 - 35 cm . therefore, vision loss, it is first necessary to overcome the long - time, near work, such as long - time read and write, watching TV, therefore, vision loss, it is first necessary to overcome the long - time, near work, such as long - time read and write, watching TV,.
used computer isoelectronic focus for each eye of the time was controlled at 50 - 60 min used computer isoelectronic focus for each eye of the time was controlled at 50 - 60 min . 3. Avoid eye posture at the time in the car, walking, lying down when reading
reading when walking or walking in the back of a book, and books to the eye distance cannot be fixed, plus the bad lighting conditions, aggravated by adjusting the frequency and amplitude of the eye, easy to cause eye fatigue reading when walking or walking in the back of a book, and books to the eye distance cannot be fixed, plus the bad lighting conditions, aggravated by adjusting the frequency and amplitude of the eye, easy to cause eye fatigue ., to read in bed, eyes not in the horizontal state, the eye distance does not coincide with the books, the books with the brightness of the light is not uniform, that doesn't have the eye of adjusting tension and are easy to put the books near the object, thus aggravating the burden on the eyes,leading to myopia , to read in bed, eyes not in the horizontal state, the eye distance does not coincide with the books, the books with the brightness of the light is not uniform, that doesn't have the eye of adjusting tension and are easy to put the books near the object, thus aggravating the burden on the eyes,leading to myopia .
4. outdoors / movement of human eyes is gradually evolving sun rays of the optical system, and let the pupils of the eye as much as possible the absorption of natural illumination, there is more of a distance - time, to protect students' eyesight is very important to while more outdoor activity / motion, promote blood circulation at the same time, the eye will have more time overlooking, also can help relax the eye muscle / nerve, eyesight protection is self - evident that the while more outdoor activity / motion, promote blood circulation at the same time, the eye will have more time overlooking, also can help relax the eye muscle / nerve, eyesight protection is self - evident that the .
Age Onset
