Tasnim,she is 11 year old, unusual pigmentation show off their shockingly bright, different big blue eyes. Eyes of this colour are rare for people of a darker skin tone, and the cause is a lack of melanin pigment in the iris of the eye. Lower levels of melanin are more commonly found in people with lighter skin tones, meaning they are more likely to have lighter coloured big eyes.Tasnim is very happy with her eyes,the eyes of four more members of the family are like his different big blue eyes.the picture is taken from a village in Chittagong, Bangladesh.
