简要总结
The objective of this intervention study was to understand the visual health status of nearly one million children and adolescents in ten provinces in China, and then to conduct intervention and evaluate the effect of intervention measures with the development of myopia as the outcome indicator. The study will be conducted in the form of a stepped intervention and will answer the following questions.
Current China children and adolescent's vision health, including the different degrees of myopia prevalence, and farsightedness reserve status. To evaluate the implementation and effect of eight appropriate technologies and six interventions developed in this study, to reduce the incidence of myopia among children and adolescents in China, to achieve the purpose of nationwide application.
In the early stage of this study, a baseline survey will be conducted on participants. In the middle stage, participants will be required to adjust the seat height regularly and increase the time for outdoor activities, etc. In the later stage, intervention measures will be evaluated based on the overall research situation to consider national promotion.

结局指标
主要结局
Changes in visual acuity in computer optometry
时间窗: Baseline, 6 months, 1 year, 1.5 years, 2 years
Optometry Automated computerized optometry is performed by an optometrist. Automatic optometry instrument using desktop computer automatic optometry, equipment requirements should conform to the "ISO10342-2010 Ophthalmic instruments: Optometry" provisions.
Changes in uncorrected vision within two years
时间窗: Baseline, 6 months, 1 year, 1.5 years, 2 years
Uncorrected visual acuity (UCVA) was measured for the right eye, then the left eye, with a E Standard Logarithm Vision Acuity Chart (GB11533-2011) in 5-grade notation (5- LogMAR), with illumination of the chart around 500lx. If one of the eyes UCVA was less than 5.0, then tests with combined lenses were conducted among the poor eye-sighted for confirming the types of ametropia (normal, myopia, hyperopia or other eye diseases)．All the measurements were recorded.
Changes in visual acuity during dilated pupil optometry
时间窗: Baseline, 6 months, 1 year, 1.5 years, 2 years
Between 5% and 10% of the participants were selected for Dilated pupil optometry.
Changes in questionnaire survey
时间窗: Baseline, 6 months, 1 year, 1.5 years, 2 years
Questionnaires based on myopia prevention and control for children and adolescents, including a questionnaire on myopia in children and adolescents.
次要结局
- Eye protection diary(Three months.)
- Qualitative interview(Baseline, 1 year, 2 years)
