What is the color in your eye made of?
melanin
Your eye color results from the amount and quality of the melanin in the front layers of the iris. Melanin comes in black, brown, red and yellow hues. The color of the iris ranges from light blue to dark brown, with green, hazel and brown also appearing on the color spectrum. Variations in our genes dictate eye color.

What are the content of the eye?
The eye is made up of three coats, which enclose the optically clear aqueous humour, lens, and vitreous body. The outermost coat consists of the cornea and the sclera; the middle coat contains the main blood supply to the eye and consists, from the back forward, of the choroid, the ciliary body, and the iris.
What are the 7 Colours that the human eye can see?
The visible light spectrum ranges from about 380 to 740 nanometers. Spectral colors (colors that are produced by a narrow band of wavelengths) such as red, orange, yellow, green, cyan, blue, and violet can be found in this range.
Why is the inside of the eye black?
The pupil is a hole located in the center of the iris of the eye that allows light to strike the retina. It appears black because light rays entering the pupil are either absorbed by the tissues inside the eye directly, or absorbed after diffuse reflections within the eye that mostly miss exiting the narrow pupil.
What is white part of eye called?
The sclera is the tough outer layer of the eyeball (the white of the eye). The slight bulge in the sclera at the front of the eye is a clear, thin, dome-shaped tissue called the cornea. The cornea directs light rays into the eye and helps focus them on the retina.
Why is my sclera blue?
[2,3] The bluish hue of the sclera is due to the thinning of the collagen fibers and increased transparency which exposes the underlying uvea. The bluish sclera, therefore, is seen in many conditions with the defective type 1 collagen formation.
What color can we not see?
Red-green and yellow-blue are the so-called “forbidden colors.” Composed of pairs of hues whose light frequencies automatically cancel each other out in the human eye, they’re supposed to be impossible to see simultaneously.
What is the black in your eye called?
Pupil: The pupil is the black dot in the center of your eye that acts as a gateway for light. It expands in dim light and shrinks in bright light. It’s controlled by the iris.
Why is my sclera GREY?
Blue sclera: If the sclera is thinner than normal, blood vessels may show through, giving your eyeballs a blue or gray hue. This may occur in people with certain health conditions.
Why are my eyes GREY?
People with gray eyes have little or no melanin in their irises, but they have more collagen in a part of the eye called the stroma. The light scatters off the collagen in a way that makes the eyes appear gray.
Why are my eyeballs GREY?
Why are the whites of my eyes not white?
Why isn’t the sclera of my eye white? Several things can cause the entire sclera to change color or spots of color to appear: Blue sclera: If the sclera is thinner than normal, blood vessels may show through, giving your eyeballs a blue or gray hue. This may occur in people with certain health conditions.
