3 Myths about Blue Eyes

We all know humans have many different eye colors like brown, blue, green, etc.  But many of these functionalities behind these eye colors, specifically the non-brown ones,  have been obscure or not well understood by people especially due to mainstream media.  So I will be debunking some myths behind certain kinds of eye colors and subsequently show the true origins and functions behind certain eye colors.  

Myth #1; Blue Eyes are due to a mutation

It is commonly accepted that blue eyes are the result of a mutation.  But do any of us really know what a mutation is?  

To put it simply we all know that human reproduction involves the passing down of existing genetic information from parent to offspring & this genetic information contains two main parts to it.  The compositional information, or the blueprint in which the human body is made, and the variational information, or all the quantitative aspects of the human body such as organ capacity, muscle mass, skull shape, etc.  

The compositional information of the human body can't be changed because that's the part of our genetic existence that is copied generation after generation and is what forms the basis of our existence itself.  

That variational information, however, can change between generations, and mutations themselves are variational differences & mutations themselves are said to e the source of variation themselves which is why a parent and child, being the same compositionally can appear to look, act, or be different from each other.  

So blue eyes are commonly determined to be a variation of human eye color but that couldn't be further from the truth.  Blue eyes are not colored by melanin, like brown eyes, blue eyes get their color from microscopic structures within the eye while brown eyes get their color from melanosome deposits, which are mobile organelles that are created by melanocytes, within the cell themselves and the concentration and amount of these melanocytes determine the degree or shades of brown color.  

Are there any quantitative differences between depositing melanosomes within nearby cells and the structures that are created by cells that give color?  of course not.  The structural coloration of blue eyes is, due to light scattering by tiny particles in fine suspension within a certain medium or in other words Tyndall Scattering which this paper, which covers an experiment done to determine blue eye color, affirms.   

"The horizontal beam across the field of the microscope was employed for this observation. Care was taken to distinguish between effects due to the irregularities of the external surface and those due to the polarizing action within the tissue itself. The iris was separated into the stroma layer, and the black pigment layer (uvea). The stroma, by transmitted light, was turbid yellow—of the same hue as that of other turbid media; the color was not localized <l in pigment granules. Against a dark ground, the stroma scatters whitish-blue light and with a 3 mm objective, a haze of tiny points of blue light was observed. The scattered light was partially polarized, and the vibrations were in the plane normal to the direction of the illuminating beam. No evidence of a blue pigment was noted; the yellow appearance by transmitted light would preclude the possibility of such a pigment being present."

The experiment thus confirms that blue eyes are due to a finely suspended structure of particles within the iris, not melanosome deposits or a mutation of pigmentation but are actually due to a non-variable compositional difference among certain humans ultimately proving that blue-eyed people are not of the same genetic composition as brown or black-eyed people.  

While there is a black-pigmented back layer behind the iris stroma; the structural color layer of blue eyes is certainly absent within most brown eyes the structural layer is absent because most brown eyes that are not mixed with blue eyes are dark and dark colors absorb light.  So Blue eyes ad brown eyes are actually polar opposites as well since blue eyes reflect and scatter light while unmixed brown or black eyes absorb light.  

Myth #2: Blue Eyes are more sensitive to Light

This is clearly a myth because of the pigmented uvea of the iris of blue eyes whichbid explained here.  

The pigment of the uvea is not purple but dark brownish-black (melanin) and serves as a background for the turbid stroma. In like manner, the choroid serves as a dark background for the sclera though the latter is frequently so thick and so opaque that the dark background is really not necessary and the sclera appears almost white.

(Mason, C. W. (1924). Blue Eyes. American Journal of Physical Chemistry, 28, 501.   https://archive.org/details/in.ernet.dli.2015.229329/page/n5/mode/2up)

A lack of melanin causes light sensitivity so clearly blue eyes aren't more sensitive to Light than brown eyed people whose dark only absorbs light.  

Myth #3: Blue and Brown Eyed prople can mix.

In order to mix something together you need to make twi different things and when combining them come up with something new.  

Do when human races mix they are mixing together their distinctive variations together which makes "new" variations because by mixing two extreme quantitative differences you end up with an intermediate variation hence race mixing creates new and interesting varieties of humans.

Blue eyes and brown eyes on contrast are not variations and they function as polar opposites.  So when blue and brown eyes mix they end up working together side by side in an anatomical association which is yet again proven by C. W. Mason.

"The development of a yellow to brown pigment in the turbid stroma would of course give shades ranging from green to hazel or brown"

(Mason, C. W. (1924). Blue Eyes. American Journal of Physical Chemistry, 28, 501.   https://archive.org/details/in.ernet.dli.2015.229329/page/n5/mode/2up)

So the existence of green, hazel, and brown eyes proves that blue and brown eye colors work together when they mix but they do not mix with each other because of their non-variable functions.  

This association is Aldo proven by the fact that their are some mixed race people who dhow this association.  These people are shown below 

.

Booker T. Washington. African-American activist, light reflective eyes, and black melanin associative coloration.  

Jeremy Meeks, Mixed African American-European, a convicted felon turned model.

 Sharbat Gula. Afghani refugee turned Italian citizen, green eyes colored by both melanin and light reflection, black hair, and dark skin.  

Lana Rockwell. American Actress, European Father, Mixed African-American & European mother.

Benjamin "Bugsy" Siegel. A Jewish-American gangster from Eastern Europe, Black pigmented hair, Light reflective Blue eyes

Sultan Al-Atrash, Syrian Druze leader, blue eyes, black hair

Mohammed Bagher Ghalibaf, an Iranian Politician with associative coloration 

Bashar Al-Assad, Syrian President of Alawite origin, has green eyes of associative coloration.

Sneha Ullal, Indian Actress. Green eyes of associated pigment and structural coloration 

 

This association of color also indicates that blue and brown people did not share or had a common ancestor in their early history because in order for two or more people to share the same ancestor they need to all be compositionally the same in biology but different in variation or quantitative expression of said biology and so blue and brown people don't share a common ancestor because of the aforementioned non-variability between the functions that causes blue and brown eyes.    

So these are some of the myths that mislead people about the truth behind blue and brown eyes through mainstream media and anyone can look into this information for themselves so don't just take my word for it.
