The Hong Kong Polytechnic University (PolyU) recently announced that a PolyU-supported start-up has successfully developed the Nano Multi-rings Defocus Incorporated Lens for controlling the progression of myopia (or short-sightedness).

The start-up collaborated with the State Key Laboratory of Ultra-precision Machining Technology (The Hong Kong Polytechnic University) (SKL-UPMT) and the School of Optometry of PolyU to create the new solution by integrating DISC technology and Ultra-precision Nano Multi-rings Machining Technology, offering children and adolescents a convenient, non-invasive and effective option to delay myopia progression.

PolyU holds the patents for both DISC technology and Ultra-precision Nano Multi-rings Machining Technology. The launch of the Nano Multi-rings Defocus Incorporated Lens signifies the University’s long-term commitment to driving research and innovation and its continuous effort in facilitating knowledge transfer and research commercialisation by supporting cutting-edge technology start-ups.

PolyU’s School of Optometry invented the novel DISC technology, which is proven to retard the myopia progression of children by 60%. The method produces a clear image on the retina and a defocused or blurred image in front of the retina simultaneously, enabling children to have clear vision while controlling the development of myopia. Based on this technology, the DISC-SH soft contact lens was introduced in 2018.

The Ultra-precision Nano Multi-rings Machining Technology, developed by SKL-UPMT, merges advanced optics design, ultra-precision machining and ultra-precision measurement technologies, and ultra-precision mould-making to apply DISC technology in spectacle lens production. By employing an ultra-precision process, 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.

The Visiting Chair Professor of the School of Optometry of PolyU and Co-founder of the start-up noted that the partnership with SKL-UPMT and the School of Optometry to launch the new Nano Multi-rings Defocus Incorporated Lens resulted in a breakthrough in DISC technology. This initiative helps address the spiralling myopia problem among children, especially in markets with a relatively high ratio of myopes such as Hong Kong, Singapore and mainland China.

The Professor of the Department of Industrial and Systems Engineering and Director of SKL-UPMT at PolyU stated that ultra-precision machining technology is a multi-disciplinary advanced manufacturing technology, which is the backbone of crucial industries like optometry, semiconductors, advanced optics, aerospace, energy, biomedical and new materials development.

He noted that SKL-UPMT is at the forefront of the development and application of technologies and have a proven track record in designing and implementing new methods, process, systems and facilities in ultra-precision machining and ultra-precision measurement.

The locally developed Ultra-precision Nano Multi-rings Machining Technology was extended to fine-tune and manufacture optometric products and will continue to create new technologies and solutions for diverse industries to benefit society. In doing so, Hong Kong and mainland China’s competence and strategic advantages in design and advanced manufacturing will be furthered, he said.

The Nano Multi-rings Defocus Incorporated Lens is expected to be rolled out in Hong Kong and mainland China soon. The company will continue collaborating with PolyU to develop new myopia control products based on DISC technology to protect the vision health of children and adolescents.

Founded by PolyU’s professor and alumni, the start-up has received financial support from the PolyU Micro Fund and the PolyU Tech Launchpad Fund. In 2018, the company secured a licence from PolyU for commercialising DISC technology, which the start-up manufactures and distributes DISC lenses at its authorised optometric clinics and fitting centres.
