Clinical Investigation of a Novel Spectacle Lens on Slowing Down Juvenile Myopia Progression
The goal of this exploratory clinical trial is to evaluate the efficacy and safety of a test spectacle lens (standard single vision lens (SVL) during first year, and standard myopia control lens (MCL) in second year), designed with passive red-light emission, for the control of myopia progression in myopic children age 6 to 11 years old, both male and female, with no systemic or ocular anomalies. The main question it aims to answer is: Does the test spectacle lens designed with passive red-light emission provide significant myopia control effect to children? Researchers will compare the standard SVL designed with passive red-light emission to SVL (first year) and MCL designed with passive red-light emission to MCL (second year) to see if the test spectacle lens work to slow down myopia progression. Participants will: * Wear the study spectacles * Visit Essilor R\&D Centre for follow-up sessions
