1. A lens for an eye, the lens having an optical axis, a focal distance and being characterized by:
an aberration profile along the optical axis, the aberration profile:
including higher order aberrations having at least three spherical aberration components selected from the group consisting of C(4,0) to C(20,0), wherein the aberration profile provides, for a model eye with no aberrations and an on-axis length equal to the focal distance:
a retinal image quality (RIQ) with a through focus slope that degrades in a direction of eye growth; and
a RIQ of at least 0.3
wherein the RIQ is Visual Strehl Ratio measured substantially along the optical axis for at least one pupil diameter in the range 3 mm to 6 mm, over a spatial frequency range of 0 to 30 cycles/degree inclusive and at a wavelength selected from within the range 540 nm to 590 nm inclusive.
