Spherical equivalent (SE) and distribution of refractive error (RE) in different age groups in Yi and Han populations. a: SE in different age groups in Han and Yi populations; b: Distribution of RE in different age groups in Han and Yi populations. Chi-square tests were used to test the distribution difference in the prevalence of RE between Han and Yi populations (p < 0.05 *, p < 0.01 **, p < 0.001 ***)
