As children and adolescents are in a critical period of visual development, the presence of asthenopia may lead to an earlier onset and increased prevalence of a range of chronic eye diseases and retinal disorders, thereby affecting their physical and mental health as well as future development. However, existing studies have mostly focused on single interventions, lacking a systematic comparison of the effects of multiple myopia control approaches on asthenopia. Therefore, the present study aims to investigate, through a cross-sectional survey, the impact of various myopia control interventions-including conventional spectacles, defocus-inducing spectacles, orthokeratology, low-concentration atropine, red-light therapy, and combined multi-intervention strategies-on asthenopia, to assess the prevalence and severity of asthenopia among users of different interventions, and to compare the differences in their effects on asthenopia. This will provide evidence-based support for the selection of individualised correction strategies in clinical practice and contribute to advancing clinical research on asthenopia in children and adolescents.",[42,43],"Myopia","Visual Fatigue","NOT_YET_RECRUITING","2026-07-02",{"date":47,"type":48},"2026-07-09","ACTUAL",{"date":50,"type":38},"2026-07-05",{"date":52,"type":38},"2027-04-30",{"name":5,"class":6}]
