Final answer:
It takes approximately 15 minutes for an officer's eyes to fully adjust to a low-light situation after coming in from outside.
Step-by-step explanation:
When entering a low-light situation from outside, it takes approximately 15 minutes for an officer's eyes to fully adjust to the new environment. This is known as getting 'dark adapted.' During this time, the pupils of the eyes open up as much as possible to let in more light, allowing the officer to see more clearly in the low-light conditions.
