Efficacy of repeated low-level red-light therapy combined with defocus incorporated multiple segments spectacles for controlling childhood myopia

Abstract

Objective: To evaluate the differences in the efficacy of repeated low-level red-light (RLRL) therapy combined with either single-vision spectacles (SVS) or defocus incorporated multiple segments (DIMS) spectacles in slowing myopia progression in children. Methods: A total of 129 myopic children aged 6–14 years were recruited between July 2023 and February 2024. Participants had at least one eye with spherical equivalent refraction (SER) 0.05). No severe adverse events or safety concerns related to RLRL therapy were observed throughout the study. Conclusion: RLRL therapy is a potentially effective and practical approach for myopia control, demonstrating comparable efficacy when combined with either SVS or DIMS spectacles.
