Objective To explore the effectiveness of scientifically using electronic screens in preschool children under the "family-school-hospital (community health)" model, providing reference and basis for eye health care in preschool children. Methods Using a field trial sampling method, educational and intervention measures for the reasonable use of electronic screens under the "family-school-hospital" model were implemented in a kindergarten in the outskirts of Shanghai. Before and after the intervention, a questionnaire survey on eye health knowledge was conducted among parents, and vision and refractive error tests were conducted among children. The study assessed parents awareness of eye health knowledge, the usage of electronic screens, and the prevalence and follow-up of poor vision. Results The parent eye health knowledge questionnaire survey showed that the average score of 312 parents during the baseline survey was 4.28±3.55 points, while the average score of 291 parents during the final survey was 8.26±2.47 points, with a statistically significant difference (P<0.001). The Mann-Whitney U test showed a statistically significant difference in childrens electronic device usage time on weekdays and holidays before and after the intervention (P<0.001). The number of valid vision test participants before and after the intervention was 309 and 286, respectively, with the proportion of children with poor uncorrected visual acuity being 12.00% and 17.10%, respectively, showing no statistically significant difference (P>0.05). The proportion of children with refractive errors was 10.70% and 14.00%, respectively, also showing no statistically significant difference (P>0.05). The re-examination rate was 57.14% and 85.71%, respectively, with a statistically significant difference (P<0.05). Conclusion The integrated vision prevention and control measures of the "Family-School-Hospital (Community Health)" model can enhance parents eye health knowledge, reduce childrens electronic device usage time, and increase the re-examination rate of children with eye abnormalities. However, further observation is needed to evaluate the effectiveness of these measures in controlling poor vision and refractive error rates.
