Abstract: Objective To understand the current situation and influencing factors of primary and middle school students' poor eyesight in Longwen District of Zhangzhou,in order to provide a scientific basis for further effective prevention and control of students' poor eyesight. Methods In 2022,a stratified cluster sampling method was used to select 1 826 primary and secondary school students from 6 schools for questionnaire survey and visual acuity examination,and the data were analyzed. Results The overall rate of poor eyesight among 1 826 primary and middle school students was 77.27%, with a higher rate among girls（83.13%） than boys（71.57%）（χ²=34.744,P<0.01）. The rates of poor eyesight among primary school students,junior high school students,and senior high school students were 62.92%,75.14%,and 91.70%,respectively,with statistically significant differences（χ²=151.402, P<0.01）. The rate of poor eyesight,myopia and the severity of poor eyesight were gradually increased with the rise of grade（χ²_trend=162.149,258.824,191.239,all P<0.01）. Frequently or consistently reading and writing with eyes more than one foot away from the book（OR=0.689,95%CI：0.540-0.879）,daily outdoor activity duration ≥ 1 hour（1-<2 h OR=0.614,95%CI：0.446-0.845;≥2 h OR=0.685,95%CI：0.475-0.985） were the protective factors for poor eyesight,while girl（OR=2.174,95%CI：1.701-2.778）,junior high school and above（junior high school OR=1.579,95%CI：1.164-2.141;senior high school OR=5.894,95%CI：3.928-8.844）,spending ≥1 h on homework after school（1-<2 h OR=1.644,95%CI：1.193-2.267;≥2 h OR=1.564,95%CI：1.085-2.254） and at least one parent had myopia（single parental myopia OR=2.010,95%CI：1.516-2.666;double parental myopia OR=5.833,95%CI：2.938-11.578） were the risk factors for poor eyesight.
