Claim Text:
1. An ophthalmic lens for minimizing visual acuity variation for a progressing myope comprising a lens having a center and at least one peripheral zone surrounding the center and having a different dioptric power than at the center, wherein said lens has power profile is selected from the group consisting of a power profile with spherical aberration, a multifocal power profile, a freeform power profile, and a segmented freeform power profile, said power profile being determined based on an initial paraxial power of a progressing myope and a defined myopia progression rate over a specific time period such that a difference in neural sharpness over the specific time period is between −0.1 and −0.5, so that changes in visual acuity at a beginning of said time period and at an end of said time period are minimized.
