Why does the eye lens not have to do all the work of converging incoming light rays?

The human eye works like a sophisticated optical system, and both the cornea and the lens play essential roles in focusing light onto the retina, where the images are formed.

The cornea is the transparent, curved front surface of the eye. It is responsible for the initial bending of light rays that enter the eye. About two-thirds of the eye's focusing power comes from the cornea. The lens, located just behind the pupil, fine-tunes the focusing process. By changing its shape through a process called accommodation, the lens adjusts its curvature to focus on objects at different distances, allowing us to see clearly at various distances.

Together, the cornea and the lens work in coordination to converge incoming light rays onto the retina, where specialized photoreceptor cells capture the light signals and send them to the brain for processing, ultimately enabling us to perceive the world around us. This collaboration between the cornea and lens is crucial for maintaining proper vision and clarity.

Therefore, the correct answer is "The cornea of the eye also converges light rays entering the eye".
