Abstract:
1. A method for reducing progression of refractive error comprising the steps of: providing an optical vision treatment device comprising a vision treatment zone and at least one vision priority zone; 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 to near the retina and substantially simultaneously providing clear on-axis images; and wherein said vision priority zone 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: peripheral defocus and other optical aberrations.
