Typical phase response curve of the circadian clock. Light exposure during the subjective day does not result in phase shifts in the circadian clock, whereas light in the early portion of the subjective night delays the phase of the clock and light in the late night advances the clock. Exposure of the clock to light from tablet-based eReaders appears sufficient to phase delay the clock, leading to disruption of sleep and subsequent daytime sleepiness on the following day.
