Correct option is D
The correct answer is (D) Iris
- The iris is the part of the eye that gives it its color.
- When the iris contains less melanin, light passes through and reflects off collagen fibers deeper in the eye. This reflection makes the eyes appear blue.
- The color of the iris can range from light blue to dark brown, depending on the amount of pigmentation.
- The iris also controls the size of the pupil, regulating how much light enters the eye.
Information booster:
- Lens: A transparent, curved structure that bends light to focus it onto the retina.
- Retina: Converts light into neural signals and sends them to the brain for processing.
- Cornea: Helps focus light as it enters the eye and controls how much light is allowed in.
