- Lens: The cornea and lens of the eye act like the lens of a camera, focusing light onto the retina, which is analogous to the film or digital sensor in a camera.

- Iris: The iris, the colored part of the eye, functions similarly to the aperture of a camera, controlling the amount of light that enters the eye.

- Retina: The retina, located at the back of the eye, contains photoreceptor cells (rods and cones) that convert light into electrical signals, just like the pixels in a digital sensor.

- Optic Nerve: The optic nerve transmits the electrical signals from the retina to the brain, similar to how a camera's electrical signals are processed and transmitted to produce an image.

These similarities allow the human eye to capture and transmit visual information to the brain, enabling us to perceive and interpret the world around us.
