Black eyes:

* The high melanin content helps protect the eyes from the sun's harmful ultraviolet (UV) rays.

Brown eyes:

* Range in color from light brown to dark chocolate brown.

* Commonly found in individuals of all ethnic backgrounds.

* Also contain melanin, but in lower concentrations compared to black eyes.

* Provide moderate protection from UV rays due to the presence of melanin.

The main difference between black eyes and brown eyes lies in the concentration of melanin in the iris. Black eyes have a higher concentration of melanin, giving them a completely black appearance, while brown eyes have a lower concentration, resulting in various shades of brown.
