1. A method for predicting an optical acuity measure of an optical system of an eye, the method comprising: a) determining a point spread function based on a wavefront measurement of an eye; b) centering the point spread function with respect to the center of the resolution target; c) convolving a resolution target with the point spread function to produce an image; and d) predicting the optical acuity measure of the optical system of the eye based on the image.
