A process for simulating correction of human eyeball for better visual acuity includes a processor and coupled memory. The memory stores program for processor to obtain geometric data and a wave-front aberration of human eyeballs and simulate an eyeball model. The eyeball model and an ophthalmic lens model are combined to form a correction system for visual acuity. According to the convex/concave lens imaging rule, and using an object placed in front of the eyeball, a determination is made of an optically uncorrected first image formed at a retina of the eyeball, and a visually-corrected second image formed at the retina of the eyeball. The first object image and the second object image can be output for comparison.
