Patent ID: 7997727

Claim:
A method for reducing progression of refractive error comprising the steps of: providing an optical vision treatment device comprising a vision treatment zone and a plurality of vision priority zones; wherein said vision treatment zone is configured with a predetermined first optical design; said first optical design selected to effect control of forward-backward positions of peripheral off-axis focal points relative to a retina; said control of positions of peripheral off-axis focal points producing at least one substantially corrective stimulus for influencing progression of refractive error while substantially simultaneously controlling the forward-backward position of a central on-axis focal point near the retina and substantially simultaneously providing clear on-axis images; wherein at least one first vision priority zone, of said vision priority zones is configured with a predetermined second optical design; said second optical design selected to control, for at least one direction of gaze a condition selected from the group consisting of: defocus and other optical aberrations; and wherein at least one second vision priority zone, of said vision priority zones is located between said vision treatment zone and said first vision priority zone and is configured with a predetermined third optical design; said third optical design selected to produce an intermediate optical power between said vision treatment zone and said first vision priority zone; and wherein said third optical design substantially minimizes aberrations.
