So my alarm clock that is about 3-4 feet away from my head when sleeping is like a digital wristwatch where the numbers are black and to see it at night it needs to be backlit.
It has 4 levels of brightness: High, medium, low, and off.
When it is on high it is bright enough to see all the shapes in my room but I still can only see in black and white vision, so I know I am seeing with my rods in my eyes and not cones.
I don't know if I should have the backlight on or turn it completely off at night because I never remember waking up at night, probably because my bed is so comfy that I just fall right back asleep so maybe keeping the light on will keep me awake when I wake up so I can try WILD or some other technique. I also know that the darker the room is the better you will sleep.
So should I have the light on or off?
I know that there is a thread similar to this one but my main reason to turn the light on is so I can wake up at night and not just fall asleep again.
