The DIMS lens is an optical lens with multiple “micro-lens segments” for slowing myopia progression, which projects constant myopic defocus (the “STOP” signal to myopia). It can slow myopic progression while providing clear vision at all viewing distances.

Spectacle lens with micro-lenses - The Hong Kong Polytechnic University (PolyU)
DIMS Spectacle Lens comprises of a central optical zone and multi-segments of constant myopic defocus surrounding the central zone and extending to mid-periphery of the lens. The solution came in the form of DIMS lens, developed in collaboration with Hoya Vision Care and based on the same defocus principles as the DISC lens.

Overview. Fingerprint. Abstract. Background: Myopia control interventions, such as defocus incorporated multiple segments (DIMS) spectacle lenses, have been adopted in school-aged children to reduce the prevalence of myopia and its complications.

randomly assigned to wear DIMS (n=93) or single vision (SV) spectacle lenses (n=90). DIMS lens incorporated multiple segments with myopic defocus of +3.50 D. Refractive error (cycloplegic autorefraction) and axial length were measured at 6month intervals.

Aims: To determine myopia progression in children who continued to wear the defocus incorporated multiple segments (DIMS) lenses or switched from single vision (SV) to DIMS lenses for a 1-year period following a 2-year myopia control trial. Methods: 128 children participated in this study.

DIMS lens wearers showed better efficacy in myopia control in children with relatively more baseline hyperopic RPR than children with relatively baseline myopic RPR. This suggests that using customized peripheral myopic defocus based on individual baseline RPR may help to improve myopia control effects.

The DIMS spectacle lens with multiple "micro-lens segments" projects myopic defocus and provides clear vision for the wearer simultaneously. It can slow down myopia progression in children by 60%, and 20% of the test subjects experienced no increase in myopia.

This study evaluated the long-term myopia control effect and safety in children wearing Defocus Incorporated Multiple Segments (DIMS) spectacle lenses. Participants who completed the 2-year RCT were followed for a total of 6 years; their cycloplegic refractions and axial length were measured.
