1. A method of operating a head mounted device, the method comprising:
capturing eye data with one or more sensors of the head mounted device, wherein the one or more sensors are configured to sense an eyebox region;
initiating an ambient light measurement with a photodetector of the head mounted device; and
adjusting a transparency of a lens the head mounted device in response to the eye data and the ambient light measurement, wherein adjusting the transparency of the lens of the head mounted device in response to the eye data and the ambient light measurement includes:
associating the eye data and the ambient light measurement to previous eye data paired with a previous ambient light measurement; and
adjusting the transparency of the lens to a previously selected lens transparency selected by a user, wherein the previously selected lens transparency corresponds to the previous eye data paired with the previous ambient light measurement, and wherein the previous eye data and the previous ambient light measurement were captured by the head mounted device during a same time period.
