The regeneration of rhodopsin is necessary for the eyes to adjust to dim light. Rhodopsin is a light-sensitive pigment found in the rods of the retina, and it breaks down when exposed to light. In low light conditions, rhodopsin is required to detect light, so a period of time is needed for it to regenerate after being broken down by bright light. This is why it takes a few moments for the eyes to adjust to dark environments after being in a bright area.
