Eye colour is basically a result of the amount of melanin contained in the iris of the eyes with more the melanin meaning darker the shade. However, with the iris implantation surgery this can be cured easily and by means of Lasik surgery also the amount of melanin in the iris can be reduced to change the colour of the iris and by extension the eyes.
Thus, you can now change eye colour and get the look you always wanted with an operation for changing iris color. It is a totally safe procedure and has been done successfully on thousands of people.
