The human eye functions like a converging lens system that forms a real and inverted image of objects on the retina at the back of the eye.
When light rays from an object enter the eye, they are refracted by the cornea and the eye lens, converging to form a sharp, real image on the retina.
Although this image is inverted (upside down and reversed left-to-right), the brain processes and interprets the visual signals to perceive the object in its correct orientation.
Thus, the eye forms a real, inverted image on the retina, and the brain corrects the orientation for normal vision.
