Final answer:
It takes about 5 minutes for the rods and cones in the eyes to adjust from the darkness of a movie theater to bright light outside. This adjustment is the transition from predominantly rod-mediated vision to cone-mediated vision as brightness increases.
Step-by-step explanation:
Jamie leaves a darkened movie theater and walks out into a bright light. Normally, it will take about 5 minutes for her rods and cones to adjust to the outside light. This time frame is necessary for the eyes to make a transition from using primarily rods in the dark environment to using cones in the brightly lit environment.
The cones are responsible for our vision in bright light, while rods are more sensitive and allow us to see in dimmer settings. Although complete dark adaptation can take up to 15-30 minutes, the initial adjustment to bright light usually takes a few minutes.
