Lens Design and Method for Minimizing Visual Acuity Variation Experienced by People with Progression Myopia. The present invention relates to contact lenses incorporating power profiles that minimize the visual acuity variation of progressing myopes based on minimization. image quality variation of neural sharpness over a specific period of time. The contact lens includes a center and at least one peripheral zone around the center and having a different diopter power at the center. The lens has a power profile selected from the group consisting of a spherical aberration power profile, a multifocal power profile, a freeform power profile and a segmented freeform power profile. The power profile is based on an initial paraxial power of a person with progressing myopia and a rate of myopia progression defined over a specific period of time, resulting in controlled change in neural sharpness, thus minimizing changes in changes in visual acuity. at the beginning of the time period and at the end of the time period.
