A Real-world Study to Evaluate the Efficacy of 650nm Low-intensity Single-wavelength Red Light in the Prevention and Control of Myopia in Children and Adolescents
Status: Recruiting
Location: See location...
Intervention Type: Device
Study Type: Observational
SUMMARY
To evaluate the efficacy and safety of 650nm low-level red-light irradiation for myopia control and prevention in children under less restrictive conditions than randomized controlled trials. Participants included children(aged 7 to 18 years, spherical equivalent error of 0.5D or below) who are already myopic at recruitment, and those who are of Emmetropia or low hyperopia.
