How Does Miyosmart Control Myopia Progression?
Miyosmart uses Defocus Incorporated Multiple Segments (D.I.M.S) technology to correct myopic refractive error. This technology uses a honeycomb-shaped treatment area to induce 'defocus' and a clear zone with your child's prescription to permit visual clarity. The defocus zone helps control myopia progression while the clear zone maintains visual correction.

This unique optical technology allows a non-invasive approach to managing myopia progression. The alternating clear & defocus zones ensures vision remains clear whilst simultaneously slowing down further myopic development.
