Abstract
A lens assembly includes a plurality of micro-LEDs coupled to one or more circuitries affixed to a surface of a lens substrate. At least one micro-LED is positioned within a viewing region of the lens substrate. The viewing region is a region through which light emitted by an electronic display passes prior to reaching an eyebox. The lens assembly may be part of a head-mounted display (HMD). An eye tracking unit of the HMD includes the one or more micro-LEDs to project light onto a portion of a user's eye and a detector to collect reflected and/or scattered light from the illuminated portion of the eye. The eye tracking unit tracks the movement of the user's eye. Based on the tracked movement, the HMD adjusts presentation of displayed content such as focus and/or resolutions of the displayed content.
