Methods: A multi-stage stratified cluster sampling method was adopted to randomly select one primary school and one junior high school in Jishou City and Yongshun County in Xiangxi region, totaling 4 schools. Among them, students from grades 4 to 6 in primary schools and all students in junior high schools were selected. One to three classes were randomly selected from each grade, totaling 2420 students, who underwent vision examinations and completed questionnaires on related myopia influencing factors. Chi-square tests were used to compare the differences in myopia detection rates among different influencing factors. Factors with statistical significance in the univariate analysis were included in the multivariate logistic regression analysis. Results: Among the 2420 students, gender, parents’ myopia, prolonged use of eyes, and students from suburban counties were identified as influencing factors for myopia, while adequate sleep and eye exercises were protective factors. Conclusion: The myopia rate among primary and secondary school students in Xiangxi region is relatively high. Joint efforts from parents, schools, the government, and professional institutions are needed to strengthen myopia prevention and control.
