Commercialisation of research results: PolyU turns novel myopia control contact lens to product
Asia-Pacific, Assistive Technology, News, January 25 2018
HONG KONG: Myopia (or short-sightedness) is a major cause of ocular morbidity for school children, especially among ethnic Chinese. The optometry research team led by Professor To Chi-ho, Head of the School of Optometry at PolyU, and Professor Carly Lam from the same School, developed the novel DISC lens for this purpose.
The award-winning DISC lens brought new hope to the myopic population. The lens is a multi-zone soft contact lens which provides clear vision and at the same time projects blurred, out-of-focus (defocused) images onto the retina to slow down excessive eye growth in myopia.
When a child has myopia, the light that enters the eye focuses in front of the retina rather than on it. The new method involves producing a clear image on the retina and another defocused or blurred image in front of the retina.
