Results Totally 997 students myopia among 2 879 students (34.6%) were investigated;There were statistically significant differences in prevalence of myopia in different nationality,different genders,different stages of learning (P<0.05);The heritability of secondary students was higher than that of first-degree relatives,while that of severe myopia was higher (0.560 4±0.066 3).Han students heritability (0.487 1±0.026 5) was higher than that of Uygur students,female students heritability (0.487 1±0.026 5) was higher than that of male students,pupils heritability (0.611 9±0.045 0) was higher than middle school students. Conclusion Students who have a family history of myopia are more likely to be short sighted than those without family history.
