But it takes about 45 minutes for your eyes to fully adapt to darkness.
So if we were to use red lighting at a level of illumination that assumes fully adapted eyes, it means people won't have sufficient brightneses for the first 45 minutes of their drive, which is likely most of it.
- pastage 4y agoI only know that I adapt in about 5min. I read books in fbreader on a black bg and red text. The backlight can be very low in that app, depending on the phone you can read with an almost black screen. I start at 50% in five min I can it down to 10%.
- munificent 4y agoAdaptation begins immediately but takes much longer to reach its full extent. Go out on a very dark night and look up at the stars sometime. After half an hour, you'll be able to see stars that you couldn't see fifteen minutes ago.
