*This abstract for appeared for patent application  number 18027286 Titled 'GLINT ANALYSIS USING MULTI-ZONE LENS'

==Simplified Explanation==

This abstract describes various devices, systems, and methods that can determine an eye characteristic, such as gaze direction or eye orientation, by analyzing the location of a glint. The process involves creating a glint by shining light on a specific part of the eye, capturing the reflected light using a sensor, and then determining the location of the glint based on the captured light. The eye characteristic is then determined based on the location of the glint.


==Original Abstract Submitted==

Various implementations disclosed herein include devices, systems, and methods that determines an eye characteristic (e.g., gaze direction, eye orientation, etc.) based on the determined location of the glint. For example, an example process may include producing a glint by producing light that reflects off a portion of an eye, receiving the reflected light at a sensor wherein the reflected light is received after passing through a multi-zone lens having a first zone and a second zone, the first zone and second zone having different energy-spreading characteristics, determining a location of the glint based on the reflected light received at the sensor, and determining an eye characteristic based on the determined location of the glint.
