Claim:
1. A method for identifying a time for capturing eye refraction data, the method comprising: (a) continuously sensing a waveform of light passing through a patient's eye over a period of time, wherein the waveform is affected by an optical property of the patient's eye; (b) continuously calculating a refractive state of the patient's eye with the sensed waveform; (c) continuously displaying an indication of a current refractive state of the patient's eye, the displayed indication of the current refractive state being continuously variable with time; (d) while displaying the indication of the current refractive state of the patient's eye, receiving a task request from a user or the patient via an interface device; and (e) in response to the received task request, displaying a target with a changing property and an indicator of a patient task to be performed by the patient, while continuously displaying the indication of a current refractive state of the patient's eye.
