Why fading happens
Sleep pressure, circadian timing, passive tasks, long sessions, and an under-stimulating environment can combine. An alert may reveal the problem, but it does not remove the cause.
Practical steps
- Follow hours-of-service and fitness-for-duty rules.
- Use approved vehicle and workplace systems.
- Stop safety-critical work when warning signs appear.
- Never interact with a phone while operating a vehicle.
Where EyeJolt fits
Use it only for stationary work away from the controls, such as desk, dispatch, monitoring, and administrative tasks. Start a session with your face visible and treat repeated alarms as a clear signal to stop and recover. Do not run it in a cab or at the wheel.
Limits
EyeJolt may miss fatigue and may false-alert. It is not a medical device, fitness-for-duty system, or replacement for sleep, supervision, staffing, or approved safety controls.
