PolyU School of Optometry and HOYA Vision Care strengthen R&D collaboration: New DIMS TED spectacle lenses clinically proven on average to achieve no myopia progression over 12 months
Myopia is a global public health issue. The School of Optometry at The Hong Kong Polytechnic University (PolyU) and HOYA Vision Care have long been committed to developing myopia control spectacle lenses to help safeguard public eye health. Building on more than a decade of collaboration, the two parties have achieved another breakthrough in advancing their patent-protected Defocus Incorporated Multiple Segments (DIMS) technology to launch a new generation of myopia control spectacle lenses featuring the Triple Enhanced Design (DIMS TED).
The three key features of DIMS TED are: (1) Defocusing segments positioned closer to the geometric centre of the spectacle lens to activate the near-peripheral retina, identified as highly responsive to the myopic defocus signal that can regulate myopia progression, thereby enhancing myopia control efficacy; (2) Higher defocus power to enable a stronger myopic defocus signal; and (3) an Extended treatment zone that covers a wider peripheral visual field.
Clinical studies have confirmed the effectiveness of this innovation. In a randomised controlled clinical trial involving 196 myopic Hong Kong children aged 4 to 12, the average results from the first 12 months of the study demonstrated that children wearing DIMS TED spectacle lenses on average showed no myopia progression, while excessive eye growth was considerably slowed. The main cause of myopia progression was effectively addressed. The study also showed that DIMS TED spectacle lenses are HOYA’s first spectacle lens with reported clinical evidence for effective control of myopia progression from the age of 4 years, as a monotherapy. The findings demonstrate significant benefits for early-onset myopia and underscore the importance of early intervention. This breakthrough sets a new benchmark for myopia control lenses and marks a milestone in the long-standing industry-research-academia collaboration between HOYA Vision Care and PolyU.
Prof. Christopher CHAO, Senior Vice President (Research and Innovation) of PolyU, remarked, “PolyU has always been committed to advancing knowledge transfer. Since 2012, we have worked closely with HOYA Vision Care. The development of the DIMS TED spectacle lenses and their clinical study provide strong scientific evidence for early intervention in myopia control, reaffirming PolyU’s global leadership in optometry. We sincerely thank HOYA for their trust in our research capabilities and look forward to strengthening our collaboration to drive commercialisation of further innovations for the benefit of society.”
Prof. Dennis TSE, Associate Professor of the PolyU School of Optometry, added, “Our team has built up extensive expertise in myopia control research, particularly in understanding how the eye responds to myopia defocus signals. The new-generation DIMS TED spectacle lenses not only effectively stop myopia progression but also slow down excessive eye growth, with remarkable outcomes in children aged 4 to 6. Importantly, the DIMS TED design maintains the safety profile of the previous generation of lenses, giving parents full confidence to have their children wear them to control myopia and protect eye health.”
Mr George KWAN, Managing Director of HOYA Lens Hong Kong Limited, said, “At HOYA Vision Care, we have always been dedicated to advancing evidence-based myopia management solutions. We are delighted to continue driving innovation and achieving breakthroughs through collaboration with PolyU. Since the launch of MiYOSMART in 2018, its patent-protected DIMS technology has earned strong market trust. It is available in over 50 countries worldwide, with more than four million parents choosing it for their children. Our mission is to improve life through vision while continually raising the standard of myopia control. The new generation MiYOSMART iQ featuring DIMS TED offers a more effective, non-invasive solution to help children manage myopia progression. It also enables parents to intervene at an earlier stage, reducing the risk of their children developing high myopia and the associated sight-threatening eye diseases in later life.”
Since our collaboration started in 2012, PolyU and HOYA have jointly developed the patent-protected DIMS Technology and launched the first generation of DIMS lenses in 2018, achieving very significant success in myopia control. To further advance this non-invasive technology, the two parties incorporated the Triple-Enhanced Design, leading to the birth of the new DIMS TED lenses.
Looking ahead, PolyU and HOYA Vision Care will continue to strengthen their industry-research-academia collaboration and further advance myopia control technologies. Together, we aim to create a clearer future for the next generation and empower children to enjoy better vision and brighter opportunities in life.
A parent of a child participant in the clinical study was satisfied with the results, as her child experienced no myopia progression after wearing DIMS TED lenses.
