Abstract
Described herein are systems and/or methods for designing a system of contact lenses with interocular refractive disparity (i.e. anisometropia) for presbyopes. An example method may comprise a step of determining a plurality of lenses for inclusion in a system of contact lenses for treating presbyopes. Each of the plurality of lenses may be configured for an optical correction and may have a power profile associated therewith. The plurality of lenses may be grouped based on the optical correction. Each of the lenses in a particular group may have a different power profile. The example method may comprise a step of creating, based at least on the plurality of lenses and an add need, a fit guide. The fit guide may provide an interocular disparity of effective add. The interocular disparity of effective add may be determined by optimizing cyclopean performance across a range accommodative demands and light levels.
