Ever wondered why we need light to see? In this episode of Fizz Pop Wow!, we explore how our eyes and brain work together to process vision. Learn how light enters the eye, how our pupils adjust, and how special cells in our retina turn light into signals for the brain. Without light, our eyes cannot send the necessary information, making vision impossible in complete darkness.

We also discover why some animals, like owls and cats, have better night vision and how our eyes adjust in dim conditions. Try fun at-home experiments to see how your pupils react to light and understand how much we rely on it for sight. Tune in to explore the science behind vision and why light is essential for seeing.
