4. ### When is spherical aberation desireable in technology, and when does it occur in nature?

Spherical aberrations are never desirable. Aberrations are departures of the performance of an optical system from the predictions of paraxial optics. Aberration leads... to compensate for aberration. This occurs in nature usually in eyes of animals that have aged such that the lens of the eye has distorted leading to spherical aberrations.
