Answer 1

The correct explanation for how the human eye focuses light is:

The human eye has a lens. This lens is controlled by muscles around it, known as the ciliary muscles, which adjust its shape to focus light on the retina. When the ciliary muscles contract or relax, they change the curvature of the lens, allowing the eye to focus on objects at different distances. This process is called accommodation. If the light from an object is not focused properly on the retina, it can appear blurry, particularly if the object is too far away or too close.
