Study on the Impact of Desk and Chair Adaptation Intervention on the Occurrence and Development of Myopia in Primary School Students

Intervention Study：Study on the Impact of Desk and Chair Adaptation Intervention on the Occurrence and Development of Myopia in Primary School Students

This study is a randomized controlled trial of a desk and chair adaptation intervention involving primary school students and their parents or primary caregivers. We compared the myopia status of students in the intervention and control groups before and after the intervention to confirm the effect of the desk and chair adaptation intervention on the development of myopia in students.

In this study, two pilot schools in Anhui Province were selected , and all students were examined by ophthalmologists, and their heights and the heights of their desks and chairs were measured in order to investigate the association between desk and chair adaptations and myopia. One of the elementary school was randomly selected for a one-year desk and chair adaptation intervention to compare the occurrence of myopia and axial growth of the students before and after the intervention in the two schools.
