Methods: A cross-sectional study was conducted in 317 children between 6 and 12 years old. A complete refractive examination was performed, including static retinoscopy without cycloplegic agents. All procedures were conducted according to the Declaration of Helsinki. Results: In total, 9.7% (95% CI: 13.07–6.52) of the examined children were myopic (spherical equivalent ≤ −0.50 D), 4.4% (95% CI: 6.66–2.14) presented astigmatism (cylinder ≤ −1.50 D), and 5.4% (95% CI: 7.89–2.91) presented hyperopia (spherical equivalent ≥ +0.50 D). Conclusion: Additional research is required to assess the prevalence of refractive errors in rural areas in Mexico, to analyze the associated risk factors, and to implement appropriate eye care plans for this population. Keywords: myopia, refractive errors, hyperopia, astigmatism
