You might have seen people having blue or green eyes! A Pakistani chai wala has also recently got famous because of his blue eyes, but a report clears that blue and green eyes are just visual illusion. In a study, Dr Gary Heiting, an accredited optometrist has confirmed that, there is nothing like blue, green or hazel coloured eyes. Every eye is brown and the rest of the colours are only visual illusion. Varied colours of eyes like blue, green, hazel, etc are nothing other than the ocular misapprehension. Human eyes have only one pigment and that is Brown, confirmed the Optometrist. Pigments in human body are resolute by a factor in iris called melanin. To summon up, melanin is the same pigment which causes skin to be tanned.
Dr Gary Heiting, the senior editor of the eye care web portal ‘All About Vision’ and a licensed optometrist while splitting lights on this matter said, “Everyone has melanin in the iris of their eye, and the amount that they have determines their eye colour. There’s really only (this) one type of pigment.” He also corroborated that, without melanin, eyes, which are actually brown coloured appear to be green or blue.
Melanin in iris is what determines pigments in human body. Irises are made of a tiny version of melanin which is defined as ‘melanocytes’ and ‘melanocytes’ only occurs in one single colour – BROWN, not in green, blue, or any other shade. As per the reports of CNN, “Scientifically all eyes are of one coloured – brown, but because of the varied amount of melanocytes in humans, the eyes spawn a visual illusion and we find eyes with different shades like blue and green. But technically, melanin is made of only one “shade” and that is brown, Heiting confirmed.
People, who bear lighter eyes have lower amount of melanocytes which enabled their eyes to be more easily engrossed and reflected in light with varied colour effects. Similarly, people with brown eyes have more melanin and less light. Hence their eyes give an impression of deeper and darker. Blue-eyed people have less melanocytes which cannot sop up as much light, and hence in lights, they reflect back with attractive colour effects, Heiting said while revealing this surprising fact.
He further added that this is medically defined as ‘scattering’. When light is sprinkled on eyes, it echoes back at smaller wavelengths, which with the colour spectrum reflects in eyes, creating a ‘blue’ shade effect.Tags: Blue Eyes, Brown Eyes, eyes, Green Eyes, study
