Objective:

To estimate the prevalence of vision impairment (VI) and effective refractive error coverage (eREC) among school children in Xinjiang, China.

Approach:
    Key Findings:
    • Over 95% of vision impairment was attributable to uncorrected refractive error (URE).
    • The effective refractive error coverage (eREC) was found to be 51.76%.
    • eREC was lower in primary school students compared to secondary school students.
    Interpretation:

    Limitations:
    • The study was limited to a specific geographic area, which may affect generalizability.
    • Data collection relied on self-reported information, which may introduce bias.
    Conclusion:

    The study highlights the burden of uncorrected refractive error among school-aged children in Xinjiang, China.
