Abstract
Official abstract text for this publication.
A method for retarding the progression of myopia in a human eye, the method comprising: 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 having at least one less negative power; wherein 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.
First claim
Opening claim text (preview).
We claim: 1. A method for retarding the progression of myopia in a human eye, the method comprising: providing a concentric annular multi-zone refractive lens including: at least one correcting zone of optical power for correcting refractive error, and at least one defocusing zone having a progressive power profile for projecting multiple defocus images or at least one non-homogenous defocused image in front of at least a part of retina to inhibit myopic eye growth, the at leas…
