Abstract: A method for retarding the progression of myopia in a human eye is provided. The method comprises providing (41) a concentric annular multi-zone refractive lens including: at least one correcting zone of optical power for correcting (42) refractive error, and at least one defocusing zone for projecting (43) at least one non-homogenous defocused image in front of at least a part of retina to inhibit myopic eye growth. The at least one defocusing zone has at least one less negative power. The correcting and defocusing zones are alternated (45) in the lens and the zones are connected (46) to each other through integrated progressive transition curves. A system for retarding the progression of myopia in a human eye is also provided.
提供了一种用以减缓在一人眼中的近视发展的方法,该方法包括(41)提供一同心环状多区折射透镜,其包括:至少一个用以(42)矫正折射误差的光学放大率矫正区,以及至少一个散焦区,其(43)在视网膜的至少一部分之前投射至少一个非均一散焦影像以抑制近视眼生长。该至少一个散焦区具有至少一个较小负值放大率;其中这些矫正与散焦区在该透镜内交替(45),而且这些区通过整合渐进变迁曲线彼此连接(46)。还提供了一种用于减缓人眼中的近视发展的系统。
