| 1. A method comprising:
using vision-realistic rendering based on aberration data to produce a rendered digital image;
presenting a person with the rendered digital image;
accepting, through a device, input from the person;
changing the refractive sharpness of the rendered digital image in response to input accepted from the person; and
calculating information about the person's vision based at least on: input from the person leading to a refractive sharpness
change made during the changing step, and a refraction model which relates visual acuity to changes in the refractive sharpness
of rendered digital imagery.
