Publication number: 20230341708Abstract: A spectacle lens can inhibit ametropia of the eyes and ensure full visibility. The spectacle lens comprises: first refraction areas and second refraction areas. Each first refraction area has a first refraction force that may be based on a prescription for correcting the ametropia of the eyes. Each second refraction area has a refraction force different from the first refraction force and may function to focus images on the positions except the retina of the eyes, to inhibit the development of the ametropia. Near the central part of the lens, the second refraction areas form a plurality of independent island-shaped areas, and the first refraction areas form the areas beyond the areas of the second refraction areas.Type: ApplicationFiled: June 29, 2023Publication date: October 26, 2023Applicants: HOYA LENS THAILAND LTD., THE HONG KONG POLYTECHNIC UNIVERSITYInventors: Chi Ho TO, Siu Yin LAM, Takashi HATANAKA, Yasutake MASUDA
