• The purpose of this study was to evaluate the prevalence rate of uncorrected refractive error and associated risk factors among Singapore school.

• This was a cross sectional study of 628 children and the participation rate was 99.8%.

• The prevalence rate of uncorrected refractive error was 22.3% (95% confidence interval (CI) 19.0% to 25.5%).

• The multivariate adjusted odds ratio of uncorrected refractive error in students with the lowest academic ability was 2.24 (95% CI 1.34 to 3.73).

• Increasing time interval since the last visit to an eye care provider increased the risk of uncorrected refractive error (trend p = 0.001).

• Uncorrected refractive error was a major problem among Singapore students and resulted in low academic ability.
