Part one:Literature reviewReviewing Chiness medicine to myopia, its name of disease., cause of disease,pathogenesis and therapies;Modern epidemiology investigate the relationships between lifestyle and visual health of the primary and middle school students. Part two:Medical record1,Objective:To investigate the incidence of myopia of primary and middle school students and to analyze influence factors of low vision in these city which in different kinds of economic development level at Guangdong Provinc, and to explore the effective ways and methods for prevention myopia, providing basis for its.2,Methods:(1)Six cities is divided into three categories as pilot according to the economical development level, each city is aparted into urban and countryside, and choose 2 primary schools and 2 middle schools from each, In addition, in the Unique Features city, we have also choose one characteristic school, we have choose two class of different grades in different school at random and observed 51 school,257 class,23867 students.(2)Testing projects including students vision, height and weight。meanwhile, according to the provisions of Control scheme of Primary and middle school students which was formulated by ministry of education to design the questionnaires,then, handing out questionnaires to students questionnaires includes students with health and students studying, with the environment, exercises and sports activities and the food situation in five parts, each part of the six issues.(3)For analysising vision and its influence factors of primary and secondary school students.3, Results:(1) The severe poor vision rate for 60%at a class of cities; some two or three categories of the city mode rate for 29.50%and mild for 23.80 %,40%the severe poor vision rate just for 40%.(2) The poor vision rate of primary and secondary school students is the same among a key schoo,a non-key school of developed city and rural key-schools, there was no significant difference among them.(3) In every city in each extraction, according to a survey of urban statistical answer is different with average visual literacy posture, literacy results show that the relationship between the students, the correct posture, average visual acuity for 5.18 than the other three incorrect posture average eyesight, there was significant difference.(4) The primary school pupils whoes have sufficient time for sleep in every day counting for 24.20%,32.3%of the secondary school students have sufficient time for sleep; the high school students, whoes enjoy adequate time for sleep in every day counting for 39.9%, sufficient time for sleep or not contacts with vision.(5) Nutritional status of Students showes, urban area students have a higher ratio of normal weight than the second city rural students in the class. While the weight of abnormal, urban area students of one type city had significantly more obesity than rural students of second type city; but, rural students of second type city had a higher proportion of malnutrition and lower weight ratio than the first type city. Data shows that obese people have an average of visual acuity than normal weight more low tendency at first one. at the second one, Poor eyesight students cotend mainly in malnutrition and low weight, accounting for 69.53%of the total. In severe visual acuity bad student, malnutrition in the student with low average vision, the minimum weight, average eyesight declines have positively correlated with the degree of malnutrition.(6) The primary and middle school students takes Chinese medicinal plant gooding for eyes at three different levels, average value of vision of the primary and middle school students is respectively 4.80+0.48,4.75±0.57,4.75±0.56, Significant difference of the eyesight exists among them (P<0.05)。(7) The influencing factors in poor eyesight are different with the increase of their ages, even the same factors in different age stages, and its influence on students'vision is different also.With increasing age, progress of study, health habits of using eye becomes less important. Against, Studies of the main factors of vision in the primaryschool, with increasing age, progress of study,it becomed more and more important for vision, in High School, it becomed the main factors of vision. So, in the provisions of Control scheme of the school Strengthen with eye health knowledge science popularization, developeding correct use eye health habits.reduce the homework burden is the key to Preventioning and controling myopia.Part three:Conclusion:1. Students with poor eyesight relates to economic and cultural level。the keystone of prevention and control of myopias shoud be carry out in the developed area and a second develop area,city schools and rural key-schools。2.
