Prof. Benny CHEUNG Chi-fai, Associate Director of the Research Centre for SHARP Vision (RCSV), Chair Professor of Ultra-precision Machining and Metrology and Director of State Key Laboratory of Ultra-precision Machining Technology, and Prof. TO Chi-ho, Member of RCSV and Visiting Chair Professor of Experimental Optometry, were featured on HOY TV’s programme “InnoAction”, introducing the Nano Multi-ring Defocus Incorporated Spectacle Lens (NMDIS) for controlling the progression of myopia.
The NMDIS lens combines two cutting-edge patented technologies—the Defocus Incorporated Soft Contact (DISC) lens and the Ultra-precision Nano Multi-ring Machining Technology (UPNMMT). The lens features annular spaced correction zones and defocus zones. The former corrects vision at the central retina, while the latter focuses light slightly in front of the retina to achieve myopia defocus. This effectively inhibits the elongation of the eyeball, hence slowing the progression of myopia.
