Objective: To analyze the current situation and characteristics of poor vision of students aged 7-18 in 26 ethnic minorities in China, and to provide scientific basis for the vision prevention and treatment measures for minority students. Methods: The 2014 national survey report on student physique and health was used to collect the data of 80 766 primary and secondary school students of poor vision selected from 26 ethnic minorities, The Chi-square test was used to compare and analyze the visual acuity of Han and Chinese students. Results: The rate of poor eyesight among primary and secondary school students of ethnic minorities was 39.17%. The girls were reported with higher rates of visual impairment than boys, and the difference was highly significant(χ2=1 127.28, P<0.01). High school girls (16-18 years old ) had the highest rate of visual impairment, reaching 63.13%. The rate of vision failure was the lowest among boys in the lower grades of primary school (7 to 12 years old), amounting to 20.50%. The detection rate of poor vision in all ethnic groups ranged from 14.68% to 62.94%. Among them, the top five groups with the highest detection rate of poor vision were Tibetan(62.94%), Zhuang(62.39%), Korean(57.92%), Hui(56.48%) and Naxi(51.35%). The five lowest ethnic groups were the aquarium(14.68%), Wa(17.96%), Kyrgyz(18.30%), Li(19.22%) and Hhani(22.30%). The differences among most ethnic groups were highly significant(χ2=7 910.34, P<0.01). Conclusion The vision level of 26 minority students in China is lower than that of the Han. But there are significant ethnic differences. While intervening in Tibet，Zhuang and other key ethnic students, we should pay attention to gender differences and strengthen the prevention and control of vision of students from all ethnic groups.
