Tasnim 11, Mehedi 06 and their grandfather Shukur Mia Family members with an unusual pigmentation show off their shockingly bright, 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 eyes. The grandfather’s name is Shukur Mia, who is photographed with his granddaughter Tasnim and grandson Mehedi. The picture taken from a village home of Chittagong city in Bangladesh.
