Researchers at the Hong Kong Polytechnic University collaborated with Hoya Vision Care, based on the myopic defocus theory, have developed a new myopia control spectacle lens, DIMS (Defocus Incorporated Multiple Segments) lens. The myopic defocus theory indicates that myopia progression can be controlled by providing clear vision and constant myopic defocus simultaneously. Research team designed this myopia control lens by incorporating many micro-lenses over the lens surface, so that the “eye still experiences a constant amount of myopic defocus” as the eye moves around different regions of the lens. It was proven in a two-year clinical trial with a sample of 160 children aged 8 to 13. The result shows that this DIMS lens technology works to curb myopic progression by up to 59%.
