Abstract：Myopia has become a global public health concern. Although traditional treatment methods have shown some effectiveness, they often come with side effects or poor patient compliance. As an emerging non-pharmacological intervention, red light therapy has gained attention due to its low risk and high compliance. Studies have found that repeated low-level red-light (RLRL) exposure can effectively slow axial elongation and delay the progression of myopia by modulating choroidal structure, improving retinal metabolism, and enhancing neural signal transmission. Multiple clinical trials have confirmed its safety and efficacy in children; however, its long-term effects and underlying mechanisms still require further investigation. This article systematically reviews recent advances in RLRL therapy, explores its application prospects and challenges, and provides a reference for future individualized strategies for myopia prevention and control.
