In the past the Navy used red light for adapting sailors to night vision. A
submarine using a periscope or surfacing in the night would be highly
visible if the lights were on. The luminance levels produced by red light
are low and the visual system reacts as if it were a darkened environment.
In recent years, with the increased use of color displays, low level white
light is used instead of red light.

Subject: two intro psych questions I can't answer
I know this was discussed a while back but (1) my browser makes looking
for stuff in tips archives EXTREMELY time consuming when it was 2 or
3 years ago and I would have to browse date by date from my browser :-(
(2) I wasn't teaching intro at the time so didn't pay attention:
(1) Why is that a red light is often used in dark light situations--
how does it affect the adaptation of rods to low light?
(2) Why is the particular symptom that comes from motion sickness's
root of a mismatch between visual and vestibular symptoms one related
to the gut primarily, i.e., nausea and vomiting?
thanks
