SCOPUS IDBiography
Prof. Jeffrey Leung, a Fellow of the American Academy of Optometry (FAAO), is an Assistant Professor at the School of Optometry, The Hong Kong Polytechnic University (PolyU). A recipient of numerous teaching accolades, he was awarded the prestigious 2025 UGC Teaching Award for Early Career Faculty. His research focuses on children's vision, investigating the development of refractive errors such as myopia and astigmatism, as well as developmental disorders including amblyopia ("lazy eye") and dyslexia. He is the subject leader for Clinical Binocular Vision and received both his Bachelor’s and PhD degrees from PolyU. His career at PolyU has progressed through several roles, including Optometrist (Research) and Research Assistant Professor. Since 2016, he has also served as a technical expert for the Hong Kong Accreditation Service.
