How does light work with eyes?

Light enters the eye through the cornea, passing through the pupil, and is then focused by the lens onto the retina at the back of the eye. The retina contains photoreceptor cells called rods and cones, which convert light into electrical signals. These signals are sent via the optic nerve to the brain, where they are processed to create visual images. This process allows us to perceive and interpret the surrounding environment.
