$\huge \star \: { \boxed{ \underline{ \mathfrak{ \purple{Answer}}}}}$

The human eye is an organ that reacts to light in many circumstances. As a conscious sense organ the human eye allows vision; rod and cone cells in the retina allow conscious light perception and vision, including color differentiation and the perception of depth. The human eye can distinguish about 10 million colors.

The front part (what you see in the mirror) includes:

Iris: the colored part.

Cornea: a clear dome over the iris.

Pupil: the black circular opening in the iris that lets light in.

Sclera: the white of your eye.

Conjunctiva: a thin layer of tissue that covers the entire front of your eye, except for the cornea.

$\huge{\boxed{\underline{\purple{\dag{\mathcal{ANSWER}{\dag}}}}}}$

The eye is made up of three coats, which enclose the optically clear aqueous humour, lens, and vitreous body. The outermost coat consists of the cornea and the sclera; the middle coat contains the main blood supply to the eye and consists, from the back forward, of the choroid, the ciliary body, and the iris.
