1. A computer device implemented method comprising:
displaying, via the computer device, content on a display device;
sensing a pupil size of a user of the computer viewing the content by:
capturing an image of the user via a computer device camera;
identifying a pupil of the user in the image; and
measuring the size of the identified pupil; and
adjusting a luminosity setting of the display device based on the sensed pupil size and a pupil size setpoint to control the pupil size to the pupil size setpoint.
