Summary

The goal of this clinical trial is to learn if our research spectacles will lower the difference in prescription (spectacles degree) between the eyes in children between 6 to 13 years old with anisometropic myopia. Anisometropic myopia is when the difference in myopia prescription between the two eyes are more than 1 diopter. The main question it aims to answer is:

* How the eye responds to the research spectacles over time by measuring:

1. Change in axial length: the physical length of the eye from front to back.
2. Change in cycloplegic spherical equivalent refraction: an accurate measurement of the eye's prescription taken while the focusing muscles are temporarily relaxed with eye drops.

Participants will:
* Wear the study spectacles
* Visit Essilor R\&D Centre and an eye clinic for follow-up sessions

Conditions

  • Anisometropia
  • Myopia

Interventions

DEVICE

More myopic eye: MCL1; Less myopic eye: MCL2

Each participant wears the study eyeglasses containing both Myopia Control Lens 1 (MCL1) and Myopia Control Lens 2 (MCL2) design, with one type of lens in each eye throughout the study period. MCL1 will be worn in the more myopic eye, and MCL2 in the less myopic eye for a period of 12 months.
