Your eyes are like magical cameras that can switch between day and night modes automatically. The pupil is like the camera’s lens, it gets bigger in the dark so more light can come in, and smaller when it's bright out so you don’t get blinded. Inside your eye, special cells called rods help you see in dim light, while cones let you see colors in bright light.
Examples
- You can still read by the light of a single lamp in the evening but might struggle in total darkness.
- It's easier to see the stars at night than during the day because your eyes are more sensitive to dim light.
