Objective To grasp the classroom visual environment status of primary and secondary schools in Fengxian District,and provide the scientific basis to improve the classroom visual environment.Methods In 2022,the visual environment of classrooms in 7 primary and secondary schools included in the national monitoring of common diseases were monitored and evaluated according to relevant standards.Results Among the visual environment monitoring indicators for classrooms in 7 primary and secondary schools in Fengxian District,the high pass rates included the window to ground ratio(100%),blackboard size(85.71%),and blackboard surface illuminance uniformity(80.95%);the low pass rates included the compliance rate of desk and chair allocation(30%),blackboard hanging height(42.86%),rear wall reflection ratio(45.24%),average blackboard surface illuminance(50%),average desktop illuminance(57.14%),and lighting coefficient(59.52%).The passing rate of the size of the blackboard and the uniformity of the illumination of the desktop in primary schools were higher than those of middle schools;the vertical distance between the lower edge of the blackboard and the floor of the podium,the reflection ratio of the back wall,and the blackboard surface illumination uniformity were lower than those of middle schools.In urban schools,the compliance rate of desk and chair allocation,the rate of the average illumination of the classroom desktop,the average illumination of the blackboard surface,the uniformity of the illumination of the blackboard surface,the lighting coefficient of the classroom,and the blackboard size were higher than those of rural schools,while the vertical distance between the lower edge of the blackboard and the floor of the podium and the reflection ratio of the back wall were lower than those of rural schools.Conlcusion The most prominent problems in the teaching visual environment of primary and secondary schools in Fengxian District are the low qualification rate of blackboard suspension height does not meet the standard,the desk and chair are seriously inconsistent with the student-height,the classroom lighting is poor,and the classroom lighting needs to be improved,and it is recommended to build a friendly visual environment for primary and secondary schools through measures such as the publicity of school health standards,joint prevention and control of departments,and the continuous promotion of the construction of pilot areas for appropriate technologies for myopia prevention and control.
