Novel Nano Multi-Ring Incorporated Defocus Spectacle Lens to Slow Down Myopia Progression

The State Key Laboratory of Ultra-precision Machining Technology (The Hong Kong Polytechnic University) (SKL-UPMT) joined hands with the School of Optometry and Vision Science and Technology Co. Ltd. (VST), a PolyU supported start-up, and have successfully developed the Nano Multi-ring Defocus Incorporated Spectacle Lens for controlling the progression of myopia (or short-sightedness).

The Ultra-precision Nano Multi-rings Machining Technology is a patented technology developed based on advanced optics design, ultra-precision machining, precision measurement, and precision moulding technology. The research team successfully applies Defocus Incorporated Soft Contact (DISC) technology for contact lens to spectacle lens production. The new spectacle lens provides added comfort for wearers, while offering more stable vision. The non-invasive design also makes it more suitable for children of different ages.

Prof. Benny CHEUNG, Professor of the Department of Industrial and Systems Engineering and Director of SKL-UPMT at the PolyU, stated: “We are delighted to extend the locally developed Ultra-precision Nano Multi-rings Machining Technology to fine-tune and manufacture optometric products and will continue to create new technologies and solutions for diverse industries to benefit society.”
