What mutation causes green eyes?
Green eyes are a genetic mutation that produces low levels of melanin, but more than blue eyes. As in blue eyes, there is no green pigment. Instead, because of the lack of melanin in the iris, more light scatters out, which make the eyes appear green.
What is Rayleigh scattering in eyes?
Rayleigh Scattering is the dispersion of light as it bounces off of air molecules. This helps determine eye colour as different light waves are captured in your eye pigment. This same scattering of light occurs in the sky which makes it appear blue.
What pigment causes green eyes?
The green color is caused by the combination of: 1) an amber or light brown pigmentation in the stroma of the iris (which has a low or moderate concentration of melanin) with: 2) a blue shade created by the Rayleigh scattering of reflected light. Green eyes contain the yellowish pigment lipochrome.
Are green eyes more sensitive to light?
The short answer to the question is yes. Light-colored eyes, including blue, green, and gray, are more reactive to the sun or bright light. Professionals refer to this as photophobia. Photophobia refers to light sensitivity.
Where do green eyes originate from?
Where Do Green Eyes Come From? Green-eyed people most commonly originate from northern and central parts of Europe, as well as some parts of Western Asia. For example, Ireland and Scotland both boast a whopping 86 percent of the population having blue or green eyes.
What causes Rayleigh scattering?
Rayleigh scattering results from the electric polarizability of the particles. The oscillating electric field of a light wave acts on the charges within a particle, causing them to move at the same frequency. The particle, therefore, becomes a small radiating dipole whose radiation we see as scattered light.
How much melanin is in green eyes?
Green irises have an uncommon melanin level — less than “truly” brown eyes, but more than blue eyes. This is why green eyes are so unique. And while 9% is indeed rare, green eyes have an even lower eye color percentage across the globe.
Does Rayleigh scattering really explain blueness of Sky?
Rayleigh scattering gives you the luminosity of the sky. Rayleigh scattering gives you a blue-white color, factors being listed above including the solar spectrum, the Rayleigh behavior, and the sensitivity of the eye, but not a really blue color.

Is ocean color affected by Rayleigh scattering?
We can say that both Raman scattering (scattering by vibrational transitions) and Rayleigh scattering are combinedly responsible for the blue colour of the ocean, yet some of its other colors like green and red are due to plant life, algae, and other factors like rocks, minerals etc.
