Green eyes don't have much melanin in them, but they also have no collagen deposits. Sometimes the stroma contains a dark pigment called melanin, and sometimes it contains excess collagen deposits.Īnd, fascinatingly, it's these two factors that control your eye colour.īrown eyes, for example, contain a high concentration of melanin in their stroma, which absorbs most of the light entering the eye regardless of collagen deposits, giving them their dark colour. The stroma, in contrast, is made up of colourless collagen fibres.
The epithelium is only two cells thick and contains black-brown pigments - the dark specks that some people have in their eye is, in fact, the epithelium peeking through. The coloured part of your eye is called the iris, and it's made up of two layers - the epithelium at the back and the stroma at the front.
