Monitoring and instigating shifts in visual focus by monitoring a first duration associated with a first focus point distance, determining that the first focus point distance satisfies a first distance threshold and that the first duration satisfies a first temporal threshold, instigating a change in the first focus point distance, yielding a second focus point distance, wherein the second focus point distance exceeds a second distance threshold, monitoring a second duration associated with the second focus point distance, determining that the second duration satisfies a second temporal threshold, and providing an output indicating satisfaction of the second distance threshold and second temporal threshold.
