Answer 1

The shape of the lens and the pupil control the clarity of images in the eye.

Step-by-step explanation:

The structure in the eye that controls the clarity of images is the shape of the lens and the pupil. The shape of the lens determines the focus of light onto the retina, while the pupil controls the amount of light entering the eye. Both of these structures play a crucial role in ensuring clear vision.
