Abstract:
1. A method, comprising: making a wavefront measurement of one or both of the person's eyes to determine information about the optical properties of one or both of the person's eyes; calculating a prescription for the person comprising a corresponding value for at least one parameter for one or both of the person's eyes based on the information about the optical properties of one or both of the person's eyes, wherein calculating the prescription comprises ray tracing light paths through one or both of the person's eyes based on the information about the optical properties of one or both of the person's eyes, determining an initial value for the at least one parameter for one or both of the person's eyes based on the ray tracing, and determining the corresponding value for the at least one parameter based on a comparison of the initial value for the at least one parameter and another value for the at least one parameter obtained from a subjective refraction of one or both of the person's eyes, wherein the at least one parameter is selected from the group consisting of sphere, cylinder, axis, addition, prism, and base; and outputting the prescription.
