The pupil is the part of the eye through which light passes.
The cornea is the avascular structure of the eye that allows light to enter. It is a transparent outer covering that refracts light onto the lens.
The iris has an opening, called the pupil, through which light enters the eye.
Light rays enter the eyeball through the cornea, the clear outer covering of the eye.
The cornea and the lens are the two main parts of the eye that allow light to enter. The cornea is the transparent outer layer that helps focus light onto the retina, while the lens further focuses the light onto the retina for clear vision.
The pupil is actually a hole located in the center of the iris. It allows light to enter into the retina. Because the light entering the eye is absorbed tissues of the inner eye, the pupil appears black. Humans have round pupils but other species may have split pupils.

The pupil is the opening in the center of the iris (the colored part of the eye) that allows light to enter the eye. By dilating or constricting, the pupil controls the amount of light reaching the retina at the back of the eye.
Cornea
The cornea is the most anterior part of the eye, serving as the transparent front surface that allows light to enter the eye.

Cornea: Transmits & focuses light into the eye. Lens: Focuses light rays onto the retina. Retina: Creates impulses to the brain. Thepupil is a hole located in the center of the iris of the eye that allows light to enter the retina.
The cornea is the part of the eye that causes the greatest bending of light rays as they enter the eye. It is responsible for about two-thirds of the eye's total focusing power.
The cornea is the outermost part of the eye that gathers and focuses light onto the lens. It plays a crucial role in the initial bending of light rays as they enter the eye.
