INTERVENTIONAL
Conditions
Summary
The goal of this clinical trial is to investigate the short-term changes in the eye structure while wearing two types of lenslet-based myopia control lenses over a period of 6 months in children aged 6 to 13 years with myopia. The main question it aims to answer is: * How the eye responds, at each timepoint, to the two myopia control lenses by evaluating: 1. Change in axial length 2. Change in choroidal thickness Participants will: * Wear the study spectacles * Visit Essilor R\&D Centre for follow-up sessions

Interventions
Myopia Control Lens 1 (MCL 1) is an ophthalmic lens intended to slow down eye growth in children. This lens will be dispensed to either the right or left eye and will be worn by the participant for a period of 6 months.
Myopia Control Lens 2 (MCL 2) is an ophthalmic lens intended to slow down eye growth in children. This lens will be dispensed to either the right or left eye and will be worn by the participant for a period of 6 months.
