AI Technical Summary
Technical Problem
Existing myopia control contact lenses often fail to provide full myopic defocus in all meridians, leading to reduced effectiveness in slowing down the progression of myopia due to astigmatism issues in the peripheral region.
Method used
A contact lens design featuring a central region for correcting vision with a first power and a peripheral region with a plurality of discrete facet surfaces that undercorrect or overcorrect visual acuity, each facet having varying powers in different directions to create myopic defocus across all meridians.
Benefits of technology
The design provides a stronger stop signal to eye growth by ensuring full myopic defocus in all meridians, effectively slowing down myopia progression compared to conventional lenses.

Abstract
Exemplary methods and apparatuses are disclosed for performing myopia control using an ophthalmic device (contact lens) including a central region configured to correct vision with a first corrective power (spherical or spherical cylindrical) and a peripheral region surrounding the central region, the peripheral region including a plurality of separate facet surfaces configured to undercorrect (or overcorrect) vision with a second corrective power, each of the plurality of separate facet surfaces having power that varies in both (i) a first direction extending radially from a central location of the central region to the periphery of the ophthalmic device, and (ii) a second direction perpendicular to the first direction.
