Eye color

Eye color or eye colour is a polygenic phenotypic character determined by two distinct factors: the pigmentation of the eye's iris and the frequency-dependence of the scattering of light by the turbid medium in the stroma of the iris.

In humans, the pigmentation of the iris varies from light brown to black, depending on the concentration of melanin in the iris pigment epithelium (located on the back of the iris), the melanin content within the iris stroma (located at the front of the iris), and the cellular density of the stroma. The appearance of blue and green, as well as hazel eyes, results from the Tyndall scattering of light in the stroma, a phenomenon similar to that which accounts for the blueness of the sky called Rayleigh scattering. Neither blue nor green pigments are ever present in the human iris or ocular fluid. Eye color is thus an instance of structural color and varies depending on the lighting conditions, especially for lighter-colored eyes.

The brightly colored eyes of many bird species result from the presence of other pigments, such as pteridines, purines, and carotenoids. Humans and other animals have many phenotypic variations in eye color. The genetics of eye color are complicated, and color is determined by multiple genes. So far, as many as 15 genes have been associated with eye color inheritance. Some of the eye-color genes include OCA2 and HERC2. The earlier belief that blue eye color is a simple recessive trait has been shown to be incorrect. The genetics of eye color are so complex that almost any parent-child combination of eye colors can occur. However, OCA2 gene polymorphism, close to proximal 5′ regulatory region, explains most human eye-color variation.

Creativity Or Fear

by: Okular

"Preparing yourself to be honest
Will it happen in your grave?”.
Laugh at your cancerous ways
With no means of repression, what the fuck can you do
but live?
Discover that life has meaning when you let that
meaning go
Put a mic to those idiots in your head
Let the posers around you laugh as they listen to
themselves
Fuck the disabled body of your fears, see it is not
yours
Give it back to whom it belongs, to no one [2x]
Creativity or fear
The choice is yours
The dangerous dignity of man
Embrace it or be consumed
By imported dreams
Investing your life in distraction
It creates fear being away from home
Around that fear you built your life
Feeling alive can happen this moment, needs no
preparation
Preparing yourself to be honest, will it happen in your
grave?
Fuck the disabled body of your fears, see it is not
yours
Give it back to whom it belongs, to no one [2x]
Put a mic to those idiots in your head
Let the posers around you laugh as they listen to
themselves
Preparing yourself to live tomorrow, you might not get
another chance
Urgency enables
The possible dignity of man
The threatening dignity of man
It shall threaten you until you love yourself
Creativity or fear, the choice is yours,
The dangerous dignity of man
Embrace it or be consumed
By imported dreams
Rip through the falsehood inhabiting the body you call
yourself
Fuck those intruders so deeply they will never return
to your home
Then fuck yourself so deeply you will never return
Then let life inhabit your body
You believe something new will emerge
Reverence for the remote controlled life
Preprogrammed options, a timeframe so limited,
Nothing substantial
Fuck your drama, seeking acceptance and a fair judgment
You cannot accept yourself!
Forget all judgments and embrace what is in your
control; your choice
Fear or creativity
Fuck the disabled body of your fears, see it is not
yours
Give it back to whom it belongs, to no one [2x]
You believe something new will emerge
Reverence for the remote controlled life
Preprogrammed options, a timeframe so limited
