KEY HIGHLIGHTS:

  • The purpose of this study was to determine the age- and gender-specific prevalences of refractive errors in Tehran through a population-based study.

  • The age- and gender-standardized prevalence of myopia based on manifest refraction was 21.8% (95% confidence interval [CI], 20.1 to 23.5) and that for hyperopia was 26.0% (95% CI, 24.5 to 27.6).

  • Prevalences of myopia and hyperopia differed significantly among the age and gender groups (P < 0.001).
