Abstract
Systems include three optical elements arranged along an optical axis each having a different cylinder axis and a variable cylinder refractive power. Collectively, the three elements form a compound optical element having an overall spherical refractive power (SPH), cylinder refractive power (CYL), and cylinder axis (Axis) that can be varied according to a prescription (Rx).

1-20. (canceled)
An optical system, comprising:
- a plurality of refractive elements each arranged along an optical axis, each of the plurality of refractive elements having an associated variable cylinder refractive power and an associated cylinder axis, wherein the associated cylinder axis of each of the refractive elements extends along different radial directions orthogonal to the optical axis;
- and
- an electronic controller configured to control the variable cylinder refractive powers, to form an optical element comprising the plurality of refractive elements and having an overall spherical refractive power (SPH), cylinder refractive power (CYL), and cylinder axis (Axis) according to a prescription (Rx).
