Question

Light and dark adaptation involves pupillary reflexes, variations in rod and cone function, and changes in the amount of available rhodopsin. Pupillary reflexes allow for the regulation of how much light enters the eye, while variations in rod and cone function allow for the detection of different levels of light. Finally, changes in the amount of available rhodopsin allow for the regeneration of photopigments in the photoreceptor cells to allow for continued visual processing in different lighting conditions.
