Abstract

In general, in some embodiments, the disclosure provides a method that includes making a subjective refraction of a person to determine information about the person's vision, 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 (e.g., aberrations), calculating a prescription for the person based on the information about the person's vision and the information about the optical properties of one or both of the person's eyes, and outputting the prescription.
