We are grateful to be able to work with a team of experts in optometry, vision science, biotechnological science, rehabilitation science, and neuroscience, joining forces with them to set up CEVR with the support of InnoHK. We look forward to seeing more technological breakthroughs in eye and vision health in the near future.” Professor Ben Thompson, CEO and Scientific Director, CEVR, said, “Globally, more than two billion people have vision impairment. In at least one billion – or almost half – of these cases, vision impairment could have been prevented or has yet to be addressed. With its mission to generate technologies to prevent vision loss in the aging global population and preserve healthy vision, CEVR is dedicated to creating synergies between world-leading researchers from PolyU and UW to facilitate related research and development, with early successes anticipated in innovative vision health solutions. With the support of the Hong Kong government’s initiative, we are confident of further driving global research collaborations, bringing great opportunities to the local I&T sector and nurturing next generation talent, while also helping develop Hong Kong into an international innovation powerhouse.” Professor Chi-ho To, COO and Deputy Scientific Director, CEVR, said, “At CEVR, we are committed to nurturing multi-disciplinary research collaborations in order to generate unique technologies and comprehensive solutions with practical applications. We see limitless potential for how and where our eye-health research and technologies can be deployed so as to better address the needs and challenges of people with vision problems, while enhancing overall vision health. Looking forward, we will continue to leverage the synergies of this international collaboration between PolyU and UW to drive more innovative and advanced research programmes and projects to tackle vision problems in the community, ultimately improving quality of life for billions of people around the world.” Within the five key research areas, CEVR is currently conducting 25 high-potential research projects to address urgent needs and challenges in eye and vision health. Myopia and Eye Growth This research primarily focuses on an increasingly global issue, which is particularly noticeable in Asian populations. The greater the prevalence and the magnitude of myopia, the higher the risk of vision loss. Despite recent progress, prevention levels are still not acceptable and the cause of myopia is as yet unknown. The research aims at finding effective methods to slow, prevent or reverse myopia progression and preserve eye health while reducing myopia-induced pathologies. As such, these studies require a multi-disciplinary, multi-faceted approach and involve refraction, ocular biometry, ocular imaging, aberrometry, molecular biology, histology and pharmacology as well as electroretinography. Ocular Drug Discovery and Delivery Research in this area is responsive to a key unmet need in eye health, which requires omitting the ocular barriers of drug delivery to the vitreous humor or retina at the back of the eye. Delivery of drugs to the eye remains a significant challenge for drug formulation scientists. Although topical eye drops are the most convenient type of formulation for delivery to the eye, they are generally restricted to use for the front of the eye and are poorly suited for delivery to the back of the eye. Therefore, the programme aims to design, formulate and characterise novel drug delivery formulations that are capable of targeting not only the anterior segment of the eye and diseases such as glaucoma, but also the posterior segment of the eye, for the treatment of diseases such as age-related macular degeneration and diabetic retinopathy. Vision Enhancement Research into vision enhancement gives particular attention to the preservation and enhancement of vision, which is crucial in addressing the increased risk for a wide range of vision problems among elderly people. These include presbyopia, which affects most people over the age of 55 in focusing on near objects and is the most common visual disorder treated by optometrists. The aim of this research is to develop new technologies that will preserve and enhance vision for elderly people as well as for individuals with amblyopia, occuring when the vision develops abnormally. Tear Film & Ocular Surface This research is committed to tackling dry eye disease (DED), which is increasing in prevalence worldwide, especially in Asian patients who have a 2-3x higher incidence. As one of the most frequent causes of patient visits to eye care practitioners and one that often requires long-term management, DED causes pain that limits day-to-day activities, leading to poor general health, reduced quality of life and often depression. It is still unknown why the incidence of DED is higher in Asians. This research aims to characterise the biochemistry of ocular surface samples in Asians, in order to identify novel markers that can be used to diagnose, and potentially to predict and treat DED. Advanced Optometric Technology This research and associated technology aims to develop a dedicated process in order to gain a deeper understanding of optometry and vision science, a field of professional practice and cutting-edge research that encompasses the health of the whole visual system. Research in advanced optometric technology is crucial for the maintenance of healthy vision in an aging population. The research programme aims to develop, validate and commercialise novel techniques for assessing eye and vision health in older adults.

PolyU develops advanced vision sensors that emulate human visual adaptability

Future autonomous vehicles and industrial cameras might have human-like vision, thanks to a recent advance by scientists from Hong Kong and South Korea. Researchers at The Hong Kong Polytechnic University (PolyU) and Yonsei University in Seoul have developed vision sensors that emulate and even surpass the human retina’s ability to adapt to various lighting levels. “The new sensors will greatly improve machine vision systems used for visual analysis and identification tasks,” says Dr CHAI Yang, Associate Professor, Department of Applied Physics, and Assistant Dean (Research), Faculty of Applied Science and Textiles, PolyU, who led the research. Machine vision systems are cameras and computers that capture and process images for tasks such as facial recognition. They need to be able to “see” objects in a wide range of lighting conditions, which demands intricate circuitry and complex algorithms. Such systems are rarely efficient enough to process a large volume of visual information in real time—unlike the human brain. The new bioinspired sensors developed by Dr Chai’s team may offer a solution through directly adapting different light intensities by the sensors, instead of relying on backend computation. The human eye adapts to different levels of illumination, from very dark to very bright and vice versa, which allows us to identify objects accurately under a range of lighting conditions. The new sensors aim to mimic this adaptability. “The human pupil may help adjust the amount of light entering the eye,” explains Dr Chai, “but the main adaptation to brightness is performed by retina cells.” Natural light intensity spans a large range, 280 dB. Impressively, the new sensors developed by Dr Chai’s team have an effective range of up to 199 dB, compared with only 70 dB for conventional silicon-based sensors. The human retina can adapt to environments under sunlight to starlight, with a range of about 160 dB. To achieve this, the research team developed light detectors, called phototransistors, using a dual layer of atomic-level ultrathin molybdenum disulphide, a semiconductor with unique electrical and optical properties. The researchers then introduced “charge trap states”—impurities or imperfections in a solid’s crystalline structure that restrict the movement of charge—to the dual layer. “These trap states enable the storage of light information,” report the researchers, “and dynamically modulate the optoelectronic properties of the device at the pixel level.” By controlling the movement of electrons, the trap states enabled the researchers to precisely adjust the amount of electricity conducted by the phototransistors. This in turn allowed them to control the device’s photosensitivity, or its ability to detect light. Each of the new vision sensors is made up of arrays of such phototransistors. They mimic the rod and cone cells of the human eye, which are respectively responsible for detecting dim and bright light. As a result, the sensors can detect objects in differently lit environments as well as switch between, and adapt to, varying levels of brightness—with an even greater range than the human eye. “The sensors reduce hardware complexity and greatly increase the image contrast under different lighting conditions,” says Dr Chai, “thus delivering high image recognition efficiency.” These novel bioinspired sensors could usher in the next generation of artificial-vision systems used in autonomous vehicles and manufacturing, as well as finding exciting new applications in edge computing and the Internet of Things. The research was published in Nature Electronics.

PolyU’s Innovation In Magnetic Field-Assisted Batch Superfinishing Awarded in 2021-22 HKAI- Equipment And Machinery Design

A novel magnetic field-assisted batch superfinishing (MABS) equipment developed by PolyU’s State Key Laboratory of Ultra-precision Machining Technology wins Certificate of Merit in “2021-22 Hong Kong Awards for Industries: Equipment and Machinery Design”. Freeform surfaces have been widely used in various high-value-added applications such as the superfinishing of surgical tools, optical molds, optical lenses, structured and freeform components, etc. However, current mass finishing technology is inadequate to achieve nanometric surface roughness of freeform surfaces to a sufficiently high level so as to satisfy the requirements of their functional applications. This invention describes a novel magnetic field-assisted batch polishing (MABP) technology which has been purposely developed to provide a novel solution for achieving nanometric fast finishing of a number of freeform components simultaneously. Magnetic field-assisted mass polishing (MAMP) method makes use of a rotational magnetic field applied outside an annular chamber which drives the magnetic abrasives to impinge on and remove material from the workpiece mounted inside the chamber.  MAMP has been proven to have high accuracy, high efficiency, and cost-effectiveness with successful applications in mass superfinishing of freeform components for surgical tools, glass optical lenses, optical molds, dental crown, etc. Table 1 shows the competitive advantages of MABP in the market. (Table 1. Competitive advantages in the market) Supported by the Government, the Hong Kong Award for Industries (HKAI) was launched in 2005, aiming to recognise the outstanding performance and achievements of local enterprises in enhancing their competitiveness in various aspects. The 2021-22 HKAI comprises six categories and Equipment and Machinery Design category is one of them. The award is assessed by the following criteria: innovation, functionality, ergonomics, cost-performance, application of technology, safety, environmental impact and marketability.
