An Exploratory Study on the Minimum Power and Frequency of Repeated Low-level Red-light to Effectively Control Myopia Progression
Status: Recruiting
Location: See location...
Intervention Type: Device
Study Type: Interventional
Study Phase: Not Applicable
SUMMARY
To explore the minimum power and frequency of Repeated Low-level Red-light (RLRL) to control myopia progression in low-myopic children aged 8-10 years, and the rebound effect of low-myopic children after discontinuation of RLRL with different combinations of power and frequency.
