wherein when the lens is disposed within the eye, the lens is less sensitive to rotational misalignment between the average axis and the astigmatic axis of the eye than a reference optic having pupil segments that are equal to each pupil segment of the lens, except that the pupil segments of the reference optic have a same astigmatic orientation.

5. The method of claim 4, further comprising angularly aligning the lens to the cornea to within an angular tolerance, the angular tolerance being within a factor of 3 to the difference between the astigmatism orientations of the at least two pupil segments.
6. The method of claim 5, further comprising angularly aligning the lens to the cornea to within an angular tolerance, the angular tolerance being within a factor of 2 to the difference between the astigmatism orientations of the at least two pupil segments.
7. The method of claim 6, further comprising angularly aligning the lens to the cornea to within an angular tolerance, the angular tolerance being equal to the difference between the astigmatism orientations of the at least two pupil segments.
