AIM: To explore the prevalence and influencing factors of poor vision among 3 014 primary school students in Wucheng District, Jinhua City, in order to provide evidence for the intervention measures of poor vision.METHODS: Using a cross-sectional study, a self-designed questionnaire was done, including general conditions and influencing factors of vision. The international standard logarithmic visual acuity chart was used for visual acuity detection. The risk factors that were statistically significant among the single factor groups were used as independent variables for multivariate Logistic regression analysis.RESULTS: A total of 1 367 students with poor vision were detected, the detection rate was 45.36%, among which mild poor vision rare was 26.08%; moderate rate was 11.51%; and severe rate was 7.76%. Multivariate Logistic regression analysis showed that senior grades, parental myopia, daily insufficient sleep and outdoor activity, overuse of electronics or computers and no eye exercise were risk factors for poor vision.CONCLUSION: The rate of poor vision among the primary school students was severe, schools should take measures to improve and prevent students' poor vision by increasing outdoor activity time, correcting poor reading and writing posture, and reducing the time spent on electronic products.

AIM:To investigate the effect of glaucoma knowledge education among community residents and knowledge source, and to provide reference for improving the awareness rate of glaucoma knowledge among residents.METHODS: From July 1, 2023 to September 30, 2023, a total of 752 residents live in two communities of Jinhua city were randomly selected to investigate the source of glaucoma prevention and treatment knowledge. In addition, comprehensive health education intervention lasted for 3 mo, awareness rate of core knowledge of glaucoma was investigated before and after the intervention, and the effect of the intervention was evaluated.RESULTS: The source of glaucoma related knowledge for radio and television was 33.4%; the mobile network was 40.9%; the health education was 21.5%. The overall awareness rate of glaucoma related knowledge before education intervention was 32.7%; the overall awareness rate after intervention was 48.4%, and the comparison before and after intervention was statistically significant(χ2=37.130, P<0.001). The awareness rate of 18 questions were statistically significant before and after the intervention(χ2≥13.341, P<0.001).CONCLUSION: The awareness rate of glaucoma related knowledge among residents was low, and mobile phone network and radio and television were the main sources of glaucoma related knowledge, so the education intervention was an effective means to improve glaucoma related knowledge.
