1. A method, comprising:
varying a cylinder refractive power of a first refractive element of a first optical element, the first refractive element having a first cylinder axis associated with the first refractive element along a first radial direction orthogonal to an optical axis;
varying a cylinder refractive power of a second refractive element of a second optical element, the second refractive element having a second cylinder axis associated with the second refractive element along a second radial direction orthogonal to the optical axis;
varying a cylinder refractive power of a third refractive element of a third optical element, the third refractive element having a third cylinder axis associated with the third refractive element along a third radial direction orthogonal to the optical axis,
wherein an effect of varying the cylinder refractive power of the first refractive element, the second refractive element, and the third refractive element is to provide an optical correction having an overall spherical refractive power (SPH), cylinder refractive power (CYL), and cylinder axis (Axis) according to a prescription (Rx).
