Question

Name the part of the eye which gives color to the eyes
A) Retina
B) Iris
C) Cornea
D) Fovea

Answer 1

Hint: Humans have a range of different eye colors from light blue to dark brown and black. The color of our eye is due to color pigmentation in a certain part of the eye. This part of the eye acts as a curtain, located in front of the yes.

Complete answer:
The color of our eyes depends on the color pigmentation in Iris (part of an eye). Iris is a thin pigmented muscular curtain-like layer, positioned in front of our eyes. It performs two main functions, as follows:
1) Pigmentation in iris is the reason for the color of our eyes, as already mentioned.
2) It also regulates the amount of light entering the eye from surrounding sources of light.
Here, it should be understood that the color of the eye does not depend on the type of pigmentation in iris. But it actually depends on the amount of pigmentation in it. If the amount of pigmentation in iris is very less, the eye appears to be blue. At the same time, if the amount of pigmentation is more, the eyes appear dark brown or black. For reference, a rough diagram of a human eye is given below.

Hence, from the above explanation, we can conclude that option B is the correct answer for the given question.

Note:
Retina receives light from surroundings through the eye-lens and converts these light rays into neural signals and further transmits them to the brain for further processing. Cornea acts as a gateway and allows the light to enter the eye for vision. On the other hand, fovea in the eye is responsible for a sharp central vision.
