Claim 4:
5. The ocular aberrometry system of claim 1, wherein the tear film hydration state comprises a synchronized tear film hydration state, and wherein the determining the tear film hydration state comprises:
controlling the wavefront sensor and an imaging sensor of the ocular aberrometry system to image the optical target at approximately a same time and/or according to a same rate; and
combining a Purkinje image data-based tear film hydration state determined based, at least in part, on Purkinje image data provided by the imaging system, with a wavefront sensor data-based tear film hydration state determine based, at least in part, on the received wavefront sensor data, by determining the average, median, and/or other statistical combination of the Purkinje image data-based tear film hydration state with the wavefront sensor data-based tear film hydration state.
