Vision is how your eyes help you see and understand what’s around you.
Your eyes are like tiny cameras, they take pictures of everything you look at, and send them to your brain so you can make sense of it.
How It Works
When you look at something, light bounces off that thing and goes into your eye. Your eye has a special part called the lens, which focuses that light onto the back of your eye, like how a flashlight shines on a wall. That’s where the retina lives. The retina is full of tiny sensors called photoreceptors, which turn the light into messages.
Sending Messages to Your Brain
These messages travel along special wires called nerves all the way to your brain, and your brain puts it all together so you can see colors, shapes, and movements, just like when you look at a picture book and know exactly what’s on each page.
It's like having a super-fast messenger who tells you everything you need to know about what you're looking at!
