Abstract
Aspects of the present disclosure describe systems, methods, and structures that provide eye-tracking by 1) steering a beam of light through the effect of a microelectromechanical system (MEMS) operating at a resonant frequency onto a corneal surface; and 2) detecting the light reflected from the corneal surface.
