Abstract
An eye is illuminated with infrared illumination light. Illuminating the eye includes illuminating an ellipsoidal lensing structure with the infrared illumination light. A wavefront image of the reflected infrared light is generated. The reflected infrared light is the infrared illumination light reflected by a retina and exiting a pupil of the eye. The ellipsoidal lensing structure redirects the reflected infrared light to a wavefront sensor that generates the wavefront image. An accommodative eye state value is generated based at least in part on the wavefront image.
