Summary
Brief summary
Currently, optical and pharmacological interventions have been developed to prevent the
progression of childhood myopia. However, no myopia control strategy has been shown to have
complete efficacy in controlling myopia progression in children. One possible reason is that
risk factors contributing to the development of myopia were not controlled in previous
clinical studies including time outdoors and near vision behaviour. This study aims to
quantify time spent outdoors and near vision behavior in myopic children and its impact on
myopia control efficacy. The outcomes of this study will guide clinicians on risk management
and improve responses to existing treatments for progressive myopia.
