Question

Quizplus · Accepted Answer

Photopigment bleaching occurs when a photopigment molecule, such as the ones found in the rods and cones of the retina, undergoes photoisomerization (a change in shape) in response to light, which results in the loss of its ability to absorb light for a period of time. This phenomenon is responsible for the temporary color blindness experienced after staring at a brightly colored object for too long, as well as the adjustment period required for our eyes to adapt to changes in lighting conditions.
