ABSTRACT: Objective: To survey the prevalence and main influencing factors of vision for preschool children aged 5 to 6 years in Linhai City, in order to provide a scientific basis for developing children’s eye health care. Methods: A random cluster sampling method was used to investigate 1591 children aged 5 to 6 years from four kindergartens and their branches in the urban area of Linhai City. Record their vision screening results, and their parents are required to fill out relevant questionnaire. Results: A total of 1591 children aged 5 to 6 years who completed the visual acuity examination and questionnaire survey, the prevalence of low naked eye vision was 17.79% (283/1591), the prevalence of ametropia was 26.15% (416/1591), and the prevalence of visual abnormality was 27.47% (437/1591). Among ametropia, there were 199 cases of astigmatism (47.84%), 176 cases of myopia (42.31%), 15 cases of hyperopia (3.61%), 15 cases of hyperopia astigmatism (3.61%), and 11 cases of myopia astigmatism (2.64%). Multivariate logistic regression analysis showed that eating less vitamin A or carotene foods in daily diet, watching electronic screens those are too bright or too dark, spending less than 2 h outdoors, and watching electronic products for more than 30 minutes each time are risk factors for children with abnormal vision. Conclusion: In family life, it is necessary to pay attention to the balanced nutrition of children, take children to participate in outdoor activities frequently, and control the use of electronic products by preschool children strictly. At the same time, visual acuity screening should be applied to children aged 5 to 6 years old early so that problems can be identified as soon as possible, and intervention measures can be implemented timely.
