What are all the features available in human iris?
Answers
In humans and most mammals and birds, the iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupiland thus the amount of light reaching the retina. Eye color is defined by that of the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm.
Explanation:
1.) Your eye colour is determined by your iris!
2.) Your iris is responsible for controlling the size of your own pupil!
3.) Your iris helps regulate the amount of light that enters your eye!
(When there is bright light, the iris closes the pupil to let in less light. And when there is low light, the iris opens up the pupil to let in more light.)
4.) Your iris usually focuses light rays onto your retina.
