研究概览
简要总结
To determine whether provision of free spectacles to rural-dwelling Chinese secondary school students with visually-significant refractive error, together with a teacher-based incentive to promote their use, increases the proportion of children going on to academic high school, as opposed to dropping out or pursuing a vocational track.
详细描述
The investigators propose in the current trial to significantly expand the evidence base for spectacle distribution as the most-effective health intervention to improve educational opportunities for China's under-served rural children and adolescents by assessing impact on school attainment.

结局指标
主要结局
Attendance at academic high school
时间窗: In July following completion of Year 3 of Middle School. This occurs after 32 months of participant followup.
This will be assessed by systematically contacting parents, teachers and students to ascertain enrolment status, which REAP has used to obtain \> 97% follow-up in previous studies of high school accession. In the event of inconsistent responses, priority will be given to responses of parents, then teachers and finally students
