Methods for determining a prescription (Rx) for a person include providing aberrometric data characterizing wavefront errors of the persons eye the aberrometric data being obtained using an wavefront sensor and comprising one or more coefficients characterizing the wavefront errors determining a starting Rx for the persons eye based on the one or more coefficients and on predetermined information relating aberrometric data and subjective refraction data for a plurality of peoples eyes and reporting the starting Rx to an eye care professional.
