Novel High Efficacy Nano Multi-ring Defocus Incorporated Spectacle Lens
The Nano Multi-ring Defocus Incorporated Spectacle (NMDIS) lens is a remarkable achievement resulting from the collaboration between Vision Science and Technology Co. Ltd (VST), a PolyU supported start-up, and PolyU. This innovative lens is designed to address the progression of myopia (short-sightedness) in children.
The NMDIS lens combines two cutting-edge technologies: the Defocus Incorporated Soft Contact (DISC) lens and the Ultra-precision Nano Multi-rings Machining Technology (UPNMMT). It features annular spaced correction and defocus zones. The DISC technology, developed by the PolyU School of Optometry, has proven to effectively slow myopia progression in children by providing clear vision while simultaneously controlling myopia development.
The PolyU State Key Laboratory of Ultra-precision Machining Technology contributed the UPNMMT, which integrates advanced optics design, ultra-precision machining and measurement technologies. This technology enables the precise manufacturing of the NMDIS lens, ensuring stability, comfort and accurate vision correction for wearers.
