The main purpose of this study was to investigate the prevalence of myopia on Jhong Siao Elementay School Students in Hualien City, the factors associated with myopia, and the relationships of each others using the cross-sectional survey. According to the principles of theoretical sampling ,we decided to enroll the first academic term of the first, second, third, fourth, fifth and sixth grades students as the sample in thisresearch who were from the elementary schools of Hualien City at the ninety-six academic year. There were 744 samples in this study. Various statistical methods, including frequency distribution, Chi-square, one-way ANOVA. The major findings of this study were as follows: 1.The prevalence of myopia was about 19.5% for boys and 19.1% for girls. Study results revealed that about 144 students were current true myopia. The myopia rate of male and female was similar. 2.Only 18 students with myopia were during Grades 1-2, but most students with myopia were during Grades 5-6. According to the data in the prevalence of myopia, it revealed that the higher grade students studied in, the more amount of myopia increased obviously. The prevalence of myopia rate is directly proportional to the students' grade level. 3.There were significant differences of subjects' grade and the degree of myopia (p<.05). Grade 5(average degree was 283.07) was about 2 times the degree of Grade 1 (average degree was 167.8). 4.There were significant variances between different grade, the Body Mass Index (BMI), and the degree of myopia for parents.
