Key Points
- Iris is responsible for giving colors to the eyes.
- If there is less melanin in the iris, light can pass through and is reflected by collagen fibres that are located deeper in the eye. The colour of the eyes becomes bluer when light is reflected back.
- The color can range from light blue to dark brown, depending on the degree of pigmentation.
- Iris is also responsible for the constriction and enlargement of pupil which decides how much light will pass through it.
- Functions of other parts of eyes:
- Lens: Transparent biconvex surface which refracts light focusing it onto the retina.
- Retina: It receives the light which lens has focused, convert the light into neural signals and send these signals to the brain.
- Cornea: It controls and focuses the entry of light into the eyes.
