METHOD AND SYSTEM FOR RETARDING PROGRESSION OF MYOPIA

摘要

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.
