How Do Our Eyes Adjust to the Dark?

Your eyes are like magical cameras that can switch between day and night mode. When you go from bright light to the dark, your eyes start working harder to catch every tiny bit of light. It takes a little time for them to get used to the dark, but once they do, you can see much better, just like switching on a nightlight in a room.
