Abstract
An eye-monitoring system monitors and relieves, or even prevents, eye fatigue in users of display screens. The system monitors indicia of eye fatigue in the user, analyzes whatever information the monitoring uncovers, and assigns a score to the monitored indicia. For example, rubbing the eyes is a pretty strong sign of eye fatigue, while the system may have to monitor pupil dilation for quite a while to decide that eye fatigue is likely. The assigned score is associated with the likelihood that the user has, or will soon have, eye fatigue. If the score so warrants, then the system takes remedial action to lessen any current fatigue and to hold off the development of more fatigue. As an example of remedial action, the system alters the visual content seen by the user to shift the content's color palette slightly or to decrease its displayed brightness.
