A. cornea
B. iris
C. retina
D. optic nerve
Correct Answer:
Option B – iris
Explanation
The iris controls the amount of light by limiting the volume of light admitted. The lens then focuses the light onto the retina, forming an inverted image. The lens changes its shape to adjust the focus on both distant and near objects, a process called accommodation.
This adjustment is done by two sets of muscles in the iris
