Dark life is beyond imagination and viewing this beautiful world is possible just because of our eyes. Every living being on this earth is gifted with a power of vision. You will be surprised to know but, the human eye has the ability to distinguish around 10 million colors. You might have noticed several eye colors but do you know the facts behind them? The color of eyes is due to the pigmentation of the iris and the reflection of light.
Majority of the Heterochromia cases are hereditary. In some cases, Heterochromia is caused due to the blood staining in the iris.
Generally, the high concentration of melanin in the iris makes the color of eyes brown. Brown eyes are classified into two, i.e. dark brown and light brown. It is said that people having brown eyes are more attractive and confident.
A dark brown eye is the result of the excess amount of melanin in the iris and it is dominant in humans.
The pigmentation of the iris depends on the concentration of melanin, so eye color varies from light brown to black. Besides this, the appearance of green, blue, hazel, red, violet color in eyes results due to the light reflection. Blue and green pigments do not exist in eyes. The phenomenon of eye color is similar to that of blueness of the sky.
The green color in eyes is the combination of an amber or light brown. The green color is caused by the low or moderate amount of melanin in the iris.
Complete dark eyes do not exist, it is the result of heavy pigmentation of melanin in the iris that makes dark brown eyes appear almost black.
Grey eyes contain a dark epithelium at the back of the iris and clear stroma at the front.
The moderate amount of melanin in the iris gives the hazel color.
The deficiency of melanin production is called albinism. The deep blue eyes at certain times appear violet.
The lowest formation of melanin also leads the eye color to be red.
Amber eyes look similar to hazel eyes, but both are different.
