Myopia is a condition in which visual images come to a focus in front of the retina of the eye, resulting  in the blurry appearance of distant objects. Myopia is also commonly known as ‘near-sightedness’. Myopia has risen dramatically among children in China, reaching 76% – 90% among older school  children, and can lead to lasting vision problems.


MiYOSMART spectacle lenses, developed in collaboration with PolyU, are a safe, easy to use, effective and non-invasive method to manage myopia in children. Based on a proprietary approach leveraging  D.I.M.S Technology (developed based on peripheral hyperopic defocus theory), MiYOSMART  spectacle lenses are based on a well-established and widely recognized theory supported by leading  researchers. The efficacy of MiYOSMART spectacle lenses, proven by a wide spectrum of evidence, has resulted in over 5 million MiYOSMART spectacle lenses having been purchased by parents across  the world since launch in 2018 and August 2023. 

HOYA Vision Care is committed to developing innovative solutions to address the growing problem  of myopia progression in children and remains steadfast in its approach to collaborate with leading  scientific institutes around the world to contribute to better treatment options that are proven effective by robust clinical trials. In addition, HOYA is dedicated to the protection of both consumers and the  integrity of its products.
