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
- Read in good light and an upright position.
- Pause for movement between chapters.
- Check recall rather than measuring time alone.
- Choose sleep when the text stops sticking.
Where EyeJolt fits
Start a stationary session with your face visible, choose a suitable alert rotation, and use repeated alarms as a clear signal to stop and recover.
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.
