Rod

Real World Example

Imagine trying to find your way around a dimly lit room at night. Much like how your eyes adjust to see basic shapes and movements in low light without distinguishing colors, rod cells in the retina function similarly. Just as your eyes focus on recognizing outlines and objects rather than colors in the dark, rod cells are specialized for detecting light intensity and movement but are not equipped to perceive color, allowing you to navigate in low-light conditions without the full spectrum of vision.
