What this trial studies

This observational study aims to evaluate the efficacy and safety of 650nm low-level red-light irradiation for controlling and preventing myopia in children aged 7 to 18 years. Conducted across at least 100 hospitals, including Beijing Tongren Hospital as the lead site, the study will follow participants for three years with data analysis at 6 months, 1 year, and 2 years. Participants will use a headworn device that delivers the red light treatment, which has been verified for safety by regulatory authorities in China.

Who should consider this trial

Good fit: Ideal candidates are children aged 7 to 18 years with myopia or low hyperopia and a spherical equivalent error of 0.5D or below.

Not a fit: Patients with significant eye diseases, systemic diseases, or those who have used similar interventions in the past year may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could provide a non-invasive method to slow the progression of myopia in children and adolescents.

How similar studies have performed: While this approach is innovative, similar studies have not been widely reported, indicating that this may be a novel intervention.
