[Neuroscience] Light and dark adaptation of the eye

I´d like to know if someone can help me with the following: Is it true
that the rods (during dark adaptation) and the cones (during light
adaptation) on the retina do all adapt to the same ambient light level
or do they just adapt to whatever light intensity hits them? If the
latter should be right this mechanism could be a powerful tool to
strech the eyes ability to deal with the enormous variations in light
intensity that we are exposed to. As I´m not totally shure that this
is the right group for this question I do cross-post it to

However, thanks a lot for your answers!
