Question: 1 / 205

Which part of the eye is the first to receive light?

Pupil

Iris

Cornea

The cornea is the first part of the eye to receive light. It is a transparent, dome-shaped structure that covers the front of the eye. The cornea plays a crucial role in the process of vision because it bends (refracts) the incoming light rays as they enter the eye, helping to focus them onto the retina at the back of the eye.

As the initial surface that light encounters, the cornea's clarity and curvature are essential for proper visual functioning. After the cornea, light then passes through the pupil, which is controlled by the iris, and subsequently through the lens. The lens further refines the focus before light is projected onto the retina, where the information is processed into images that the brain can interpret.
