Lenses and methods for delaying progression of myopia

Abstract

The present invention provides a concentric annular multi-zone lens (1) for delaying the progression of myopia in a human eye. The lens (1) comprises: a plurality of correction zones (120-127) for forming a focused image on the retina of a human eye to correct refractive errors of the human eye, wherein the correction zones (120-127) have similar diopters; a plurality of out-of-focus regions (131-137) for forming an image before the retina to produce a myopic out-of-focus; and an out-of-focus increasing region (15) in which the diopters of the out-of-focus regions (131-133) are gradually corrected toward the periphery of the lens, thereby producing a greater amplitude of myopic out-of-focus at the periphery of the retina; wherein the plurality of correction zones (120-127) and the plurality of defocus zones (131-137) are alternately arranged in the concentric annular multi-zone lens (1). 本发明提供了一种用于延缓人眼的近视进展的同心环形多区镜片(1)。该镜片(1)包括：用于在人眼的视网膜上形成聚焦图像以矫正人眼的屈光不正的多个矫正区(120‑127)，其中所述矫正区(120‑127)具有相似的屈光度；用于在视网膜之前形成图像以产生近视离焦的多个离焦区(131‑137)；以及离焦度增大区(15)，在该离焦度增大区(15)中，离焦区(131‑133)的屈光度朝向镜片的周边逐渐变得更正，从而在视网膜的周边处产生更大幅度的近视离焦；其中所述多个矫正区(120‑127)和所述多个离焦区(131‑137)在所述同心环形多区镜片(1)中是交替布置的。
