Dark adaptation . Dark adaptation . primarily involves improvement of acuity and color vision involves accumulation of rhodopsin results in inhibition of rod function is much faster than light adaptation

involves accumulation of rhodopsin

Explanation:

This is because dark adaptation is the ability of the eye to react to low light sensitivity and all the rod pigments of the eye bleached out which is as a result to the bright light and this make the rods nonfunctional in the initial state . Once you are in the dark, rhodopsin regenerates and tthis lead to increase in retina sensitive continuously.
