    Astigmatism prevalence among school-aged children in Beijing is 43.6%, predominantly mild and characterized by the with-the-rule subtype.

  • 2

    The severity of astigmatism increases with advancing educational stages, with males more susceptible to the with-the-rule orientation.

  • 3

    Astigmatism magnitude significantly impairs uncorrected visual acuity, especially in non-myopic and low-myopic eyes.

  • 4

    The functional impact of astigmatism axis orientation on visual acuity is clinically negligible despite statistical significance.

  • 5

    Targeted monitoring and correction strategies for astigmatism may benefit from being tailored to specific genders and refractive profiles.
