Several recent Best Evidence in Brief articles describe the positive effects on reading achievement of providing free vision screening and glasses to pupils who need them. Adding to the evidence showing that vision is one of the most important health outcomes for academic success, a recent study describes the results of one such programme, Florida Vision Quest.
Florida Vision Quest (FLVQ) is a programme designed to provide pupils in high-poverty schools with vision screening and free vision testing in a mobile vision clinic. If children are found to need glasses, they receive them at no charge. Two pairs are given to each child.
Within three school districts in Central Florida, elementary Title I schools were randomly assigned to one of three treatments: Full treatment (n=19), screen only (n=19), or control (n=38). Only pupils in grades 4 and 5 (Year 5 and 6) were involved in the study. Outcomes were determined for all pupils in those grades, not just those who needed glasses.
Findings showed there were significant positive effects on reading (Florida Comprehensive Achievement Tests, or FCAT) for schools that received the full treatment (effect size = +0.13) but not for those that received screening only. There were no effects for maths.
