Innovative technologies developed by the Centre for Eye and Vision Research (CEVR), a collaboration between the University of Waterloo and the Hong Kong Polytechnic University, have earned gold medals at the Asia Exhibition of Innovations and Inventions in Hong Kong. The groundbreaking inventions offer promising solutions for individuals with visual impairments and those at risk of macular degeneration.
Dr. Ben Thompson, a professor at Waterloo’s School of Optometry & Vision Science and the CEO and scientific director of CEVR, expressed enthusiasm for the recognition, stating, “It’s encouraging for our teams to be recognized in this way and an indication of the maturity of these inventions. This recognition will help accelerate the transition of these projects from research to commercial success.”
The first award-winning invention introduces the world’s first quantum technology in vision science. Developed through collaboration between quantum optics experts and vision researchers, this innovation aims to detect macular degeneration at its earliest stages. Macular degeneration, a leading cause of vision loss in individuals over 55, affects millions globally, severely impacting daily activities.
The quantum imaging diagnostic tool utilizes a structured light beam perceived differently by those with macular degeneration. Dr. Thompson explained, “The quantum team has developed a laser beam that can be wrapped around a central beam like a corkscrew. It’s a complex 3D pattern of light polarization.” When observed through the human eye, the polarization interacts with nerve fibers at the back of the eye, projecting a starburst pattern sensitive to early retinal changes.
Clinical testing with a prototype, based on patient reports, has shown promising results. The team is working on an improved system that directly records reflected light structure, making the technology less subjective. A spin-out company, Incoherent Vision Inc., has been established to commercialize the screening system.
The second award-winning technology addresses the challenges of safe navigation for those with vision loss. An augmented reality navigation system, compatible with any extended reality headset, utilizes artificial intelligence to identify the user’s surroundings and guide them safely through obstacles. The ObstAR system, developed with input from individuals with visual impairments, features an arrow indicating a safe path and alerts users to hazards through sound or vibration.
Real-world user data and feedback are currently being collected, with plans to launch a spin-out company next year. Dr. Thompson emphasized the inventions’ potential impact on enhancing independence and productivity, stating, “Both projects aim to help people lead independent, productive lives, which is good for them and good for society.”
The recognition at the Asia Exhibition of Innovations and Inventions in Hong Kong highlights the inventive and transformative nature of these projects, positioning them as leaders in addressing challenges faced by individuals with visual impairments and those at risk of macular degeneration.
