The pupil is the center round black part of the eye. This is where the light enters into the retina. The human pupil works much like the aperture of a camera.
The size of the pupil in the human eye is controlled by the iris, which is a ring of muscle that can expand or contract to adjust the size of the pupil.
Assuming a pupil is a human being, the average adult human body contains about 16% carbon by weight. So in a 60kg pupil, there would be approximately 9.6kg of carbon.

Sheep eyes have a horizontal, elongated pupil, which provides a wider field of vision, allowing them to spot predators more effectively. In contrast, human pupils are round and allow for more focused vision and depth perception. This difference in pupil shape is adapted to each species' specific needs for survival and environmental awareness.
When exposed to a bright light, the pupil of the human eye will contract. This action allows less light to come in contact with the lens.
