OG exemplary drawing
 
1. A display system with reduced power use, comprising: an inward-facing sensor;
a display; and
processing electronics in communication with the inward-facing sensor and the display, the processing electronics configured to:
detect a first change in a user's eye status using the inward-facing sensor,
detect a second change in the user's eye status,
reduce a current drain of the display system in response to detecting the first change in the user's eye status, and
increase a current drain of the display system in response to the detected second change in the user's eye status,
wherein detecting at least one of the first change or the second change in the user's eye status comprises monitoring images of the iris or pupils obtained by the inward-facing sensor,
wherein reducing the current drain of the display system comprises configuring a graphics driver associated with the display to reduce an amount of power consumed by the display system over multiple frames without turning off the display.
