Abstract
A system for adjusting a position of a lens in a wearable device is provided. The system may include a wearable device and a processor. The wearable device may include a display, a lens movably disposed in front of the display, and an eye tracking device including an illuminator and an image sensor. The processor may receive data from the eye tracking device, and determine, based on the data, a first position of the eye of a user wearing the wearable device, where the position is relative to a second position which is fixed with respect to the lens. The processor may also be configured to determine a distance between the first position and the second position, and if the distance is greater than a first value, cause information to be presented to the user indicating that the lens should be moved to a more optimal position.
