sometimes I think about my own character development
Eye showing the inner surface of the iris, pupil, and ciliary processes. The lens was removed to show the posterior surface of these structures.
The iris regulates the amount of light that enters the pupil by changing its size and it is what gives the eye its color*.
Eyes are awesome, they are like the entrance to a human’s soul.

*In humans, the pigmentation of the iris is the determining factor for the colour. The concentration of melanin in the iris pigment epithelium (located on the back of the iris), is the important thing. If you have no or very few melanin, your eyes appear blue. Thats why many baby’s have blue eyes, because their melanin production has not started yet, and then the eye colour changes during their development. The amount of melanin is genetically determined. Its the same substances that makes the skin dark. That explains why for example African people have dark skin and always dark eyes (much melanin) and many northern european people blue eyes.
