This sample optics Demonstration was created using
Optica 3, an application package available for
Mathematica.
In the program, the thin lens defocusing element is governed by the input defocus parameters

and

(in diopters). The defocus angle determines the angle of rotation (in degrees) about the pupil center for the defocus effects. The scatter parameter is used to specify the diffuseness of the retina. The pupil size parameter determines the diameter of the pupil opening. Spatial units are in millimeters.
