Abstract: An embodiment of an eye-mountable device includes an optical lens; an accommodation actuator to provide vision accommodation for the optical lens; a controller including an accommodation logic to select one of a plurality of vision accommodation states for the device, the plurality of vision accommodation states including at least a failsafe focal distance; and a failsafe subsystem including a system health detector, the system health detector to monitor for one or more operational indicators for the device, wherein the failsafe subsystem is to cause the device to transition to a failsafe mode upon the failsafe subsystem identifying a failure condition for the device, the failsafe mode includes setting the vision accommodation state to be the failsafe focal distance.
