Pupil it is centre dark opening in the centre of pupil . Its size varies with the amount of light entering the retina. It is responsible for the colour of eye.
The iris (plural: irides or irises) is a thin, circular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina. Eye color is defined by that of the iris.
Ciliary muscles : A circular muscle that relaxes or tightens the zonules to enable the lens to change shape for focusing. The zonules are fibers that hold the lens suspended in position and enable it to change shape during accommodation.
Corea is the transparent layer forming the front of the eye.

Hi there!
✨ Cornea:
It is a transparent spherical membrane covering the front of the eye. Light enters the eye through this memberane. Most of rhe refraction of light rays entering the eye occurs at the outer surface of the Cornea.
✨ Pupil:
It is a small hole between the Iris through which lighg enters the eyes. In dim light, it opens up completely due to expansion of iris muscles, but in bright light it becomes very small due to contraction of Iris muscles.
✨ Ciliary muscles:
They hold the lens in position and help in modifying the curvature of lens.
✨ Iris:
It's a dark muscular diaphragm between the Cornea and the lens. It control the size of Pupil. It is the color of Iris that we call the color of the eye.
Cheers!
