Summary
Classroom sanitary conditions significantly impacted student refractive status, with increases in myopia and astigmatism. Improving the visual environment is crucial for student eye health.
Area of Science:
- Ophthalmology
- Environmental Health
- Public Health
Background:
- Investigates the link between classroom environment and student vision in Shanghai.
- Focuses on high school students facing academic pressure and extensive classroom time.
Purpose of the Study:
- To determine the correlation between classroom sanitary conditions and changes in uncorrected visual acuity and refractive status.
- To identify specific classroom environmental factors influencing student vision.
Main Methods:
- Cluster random sampling of 48 classrooms from 8 high schools.
- Followed 1087 students for one year, collecting refractive data.
- Employed a generalized additive model to analyze associations.
Main Results:
- Significant increases in spherical equivalent, cylinder, and corneal astigmatism observed.
- No significant change in uncorrected visual acuity.
- Classroom per capita area, blackboard size, and display distance affected visual acuity and refractive status.
Conclusions:
- Schools must meet national standards for classroom visual environments.
- Improving compliance rates for environmental factors is essential for student eye health.
