Abstract
Techniques are disclosed for systems and methods to provide dry eye and/or tear film hydration monitoring in the context of ocular aberrometry. An ocular aberrometry system includes a wavefront sensor configured to provide wavefront sensor data associated with an optical target monitored by the ocular aberrometry system and a logic device configured to communicate with the wavefront sensor. The logic device is configured to receive ocular aberrometry output data including at least the wavefront sensor data provided by the wavefront sensor, determine a tear film hydration state associated with the optical target based, at least in part, on the received ocular aberrometry output data, and generate user feedback corresponding to the determined tear film hydration state based, at least in part, on the received aberrometry output data and/or the determined tear film hydration state.
