Abstract Reduced vision in young children is difficult to detect therefore vision screening is recommended in school (4-5 years). Approximately 15% of children are referred for a further detailed eye examination. However 30% of children fail to attend and of those attending 50% fail to adhere to spectacle wear. The aim of the study was to examine the impact of adherence to spectacle wear on developing vision and literacy in children during their first three years of school. MethodsBaseline epidemiological data, literacy measures, vision screening results and repeat measures of vision (logMAR visual acuity) and literacy (Woodcock reading mastery test) were collected. 2930 children participating in the Born in Bradford (BiB) cohort study participated in the study. 432 (14.7%) children had failed vision screening and were referred for follow-up investigation; they were defined as the treatment group. A further 512 children from the same schools (randomly selected) who had passed vision screening were defined as the comparison group, giving a total of 944 participants. Children were retrospectively classified as adherent (wearing spectacles at follow-up examinations) or non-adherent. ResultsVision improved with adherence to spectacle wear, -0.017 (95% CI -0.020 to -0.015) log units per month (twice the rate of comparison group). Early literacy is affected by the level of vision, even after adjusting for socio-economic factors (-0.33, 95% CI:-0.54 to -0.12), the literacy score reducing by 1.5% for every one line (0.10logMAR) reduction in vision. ConclusionsDuring visual maturation, the presence of refractive error may contribute to a reduction in vision and early intervention is required. This study demonstrates that wearing spectacles is an effective intervention to improve vision and will also impact positively on developing literacy.
