Brief Summary:
The purpose of this study is to examine the efficacy and performance of the variant of Defocus Incorporated Spectacle lenses on controlling myopia progression in fast progressing myopic children.
Detailed Description:
The variant of Defocus Incorporated Spectacle lenses (D2) is a multifocal spectacle lens that produces myopic defocus images and corrects distance refractive errors at the same time.
Participants will be randomly allocated to either single vision lens group (control) or the variant of Defocus Incorporated Spectacle lens (D2) group (treatment). After 12 months of lens wear, the SV lens prescribed to the control group will be replaced with the D2 lens and be monitored for another 12 months. In parallel, the D2 treatment groups will continue their corresponding intervention for 12 months. Their cycloplegic refraction and axial length will be monitored every 6 months over 2 years. The changes in refractive errors and axial length in two groups will be compared.
