Light adaptation is the process of adjusting to bright light
after exposure to dim light This process often takes a minute or
two to be completed Dark adaptation, on the other hand, refers to
the process of adjusting to dim light after exposure to bright
light It may take half an hour or longer depending upon the level
of exposure
Light and dark adaptation takes place due to photochemical
processes Light adaptation takes place when the molecules of
rhodopsin or visual purple in the rods of the eye get bleached or
broken down, as a result of the action of light Dark adaptation
takes place when the light is removed allowing for restorative
processes that regenerate the pigment in the rods with the help of
vitamin A
