Document Type and Number:
WIPO Patent Application WO/2023/168773
Kind Code:
A1
Abstract:
Disclosed is a spectacle lens, comprising: a first region having refractive power used for correcting refractive error in vision; and a second region having the function of not focusing and not imaging; the first region and the second region are disposed on the surface of the lens, the second region comprises a plurality of sub-regions independent of each other, and the first region is a region other than the second region on the surface of the lens. In the present invention, the first region of the spectacle lens has the function of focusing an image on the retinas of eyes and correcting refractive error, and the second region of the spectacle lens has the function of limiting image focusing. By means of a combination of the first region and the second region, imaging is limited in front of or behind the retinas by means of the second region while an image of an object formed by means of the first region is visually distinguished, thereby inhibiting or at least slowing down the development of myopia and hyperopia.
