Issue Date: | 28-Nov-2017 | Source: | US Patent 9,829,722 B2. Washington, DC: US Patent and Trademark Office, 2017. | Abstract: | 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. | Rights: | Assignee: The Hong Kong Polytechnic University |
