There are a number of advantages to using a red light over a white screen or your camera flash:
1) Red light preserves your night vision
2) Red light is less noticeable in the dark, so you can read while sharing a bed or room without disturbing others, and
3) Blue/white light disrupts your circadian rhythms, delaying the release of the sleep-inducing hormone melatonin and making it harder for you to fall asleep.
