Why does it take our eyes longer to adjust from light to dark than from dark to light?

Turning off lights in a room, will take eyes a few minutes to adjust and start to make out objects. turn light on and after initial sudden flare in eyes we can see everything.

The pigment protein in the rods of our retina, rhodopsin, is responsible for our low-light vision capabilities. When it absorbs light, it photobleaches, becoming inactive, until it is recharged by the biological processes in our eyes. When we are in bright light, all of the rhodopsin is photobleached and the rods no longer function, and our vision is dominated by the cone cells (which work in bright light). So, when dark conditions occur, the rhodopsin has a chance to regenerate, but this takes time (around 30 minutes or so to fully regenerate). Thus it takes some time before our ability to see well in the dark begins to work well again.

Photopsin, the pigments that work in our cones, have a similar process but they are much less light-sensitive. However, with really bright sources of light they can photobleach too, which is why when you see something really bright, it can leave a dark spot in the place where the bright image was for awhile. All the photopsin pigments in that area have photobleached out and need time to regenerate to re-enable normal vision.
