Eye colors

Less then 35% of the Ger­man popu­la­ti­on have brown eyes. Seen world wide, it is the the most com­mon eye color.
Only 1,6% of the worlds popu­la­ti­on has green eyes
A child does not nec­ces­sa­ri­ly need to inherit the par­ents eye color
The color of the iris is depen­dent on the amount of the pig­ment mela­nin.
Blue eyes got only a litt­le mela­nin. The dar­ker the eye color, the more of the pig­ment is pre­sent.

Blue Eyes

Blue eyes most­ly have a clear­ly dis­tinc­tive struc­tu­re.
The sin­gle mus­cle fibers of the iris are often visi­ble without any magni­fi­ca­ti­on and go off radi­al oud­ward­ly of the iris.
Blue is not blue…
Even wit­hin a sin­gle eye the­re can be various shades of blue and nuan­ces.

Brown Eyes

Brown Iri­des do not con­tain any visi­ble mus­cle fibers. The con­sist of various lay­ers of dif­fe­rent shades of brown. Some even look like cra­ters or waves of the oce­an. If the iris is very dark it is often not even pos­si­ble to see any struc­tures at all. But with our spe­cial iris pho­to tech­ni­que we bring light into darkness.
Brown eyes are actual­ly blue in deeper lay­ers. The brown mela­nin coa­ting only exists in the top lay­er.

Green Eyes

The struc­tu­re of the green iris is simi­lar to tho­se of blue eyes. It is well visi­ble but often a bit more ran­dom and less strai­ght for­ward.
Howe­ver the most inte­res­ting part here are the color: 
Most of eyes which usual­ly appear geen are actual­ly com­pri­sed of mul­ti­ple colors and only appear green. With our iris pho­to­gra­phy you can see that often the main color is blue. In this cases the­re is a yel­low ring clo­se to the pupil.
Due to the fact that the­re are no true green pig­ments the eyes can appear in many colors depen­ding on the sur­roun­ding light color. 
But of cour­se the­re are tru­e­ly green eyes but they are very rare. Only 1,6 % of the worlds popu­la­ti­on has a green iris.  The big­ge­st part of the­se humans one can find in eas­tern Euro­pe, in the Bal­tic and in the Rus­si­an speakting part of the world as well as part­ly in Ger­many.

By the way…

… men see dif­fe­rent then women: They see a bit more blu­eish, bet­ter see moving objects but can`t see con­trasts as well.

… women howe­ver see more shades of green.

… that 6 of 10 peop­le in Ger­many wear glas­ses or con­tact len­ses.

… hetero­chro­mia is when one per­son has two dif­fe­rent eye colors. It is very rare and occurs in only 1 of 4 mil­lion cases.
…the mus­cles which are moving the eyes are using  1/4 of the total ener­gy of the body.

… the reso­lu­ti­on of the human eye equals 576 mega­pi­xel.
