How Do ‘Lenses’ Work in Cameras and Human Eyes?

Lenses work like magical windows that let you see things clearly. In your eye, a special lens focuses light from the world so you can see it, just like in a camera. If the lens is out of shape or dirty, everything gets blurry. That’s why glasses help people see better! When a camera takes a photo, its lens lets only the right amount of light hit the film or sensor, making sure the picture comes out sharp.
