Introduction:
The widespread use of digital devices in modern workplaces has led to a rise in visual health problems, such as myopia and dry eye syndrome, among the working-age population. This study aims to investigate the incidence of eye disorders, associated risk factors and relevant biomarkers in Shenzhen, addressing a crucial gap in the research on visual health in rapidly urbanising Chinese cities.
Methods:
This prospective observational cohort study, conducted from September 2024 to December 2029, will recruit 3000 full-time employees aged 18-65 in Shenzhen through multistage sampling across five job sectors. Data collection will include questionnaire surveys, standardised scale assessments, ophthalmic examinations, ophthalmic imaging and biomarker testing. Annual follow-ups will track the incidence of high myopia and dry eye, as well as associated factors and biomarker changes. Data accuracy will be ensured through double entry and continuous quality control.
Ethics And Dissemination:
The study has been approved by the Ethics Committee of Shenzhen Eye Hospital (2024KYPJ012; 04 February 2024). The results will be presented at professional conferences and submitted for publication in peer-reviewed journals.
Trial Registration Number:
National Health Information Platform (MR-44-24-026548).
