Julie can see very well close up, but has more problems with distance vision. She really has trouble when looking from her paper up to the professor at the front of the class and back again. What part of her eye is most likely the problem?
A) optic nerve
B) fovea
C) cornea
D) ciliary muscle
E) suspensory ligaments
Ciliary Muscle
A ring of smooth muscle in the eye's middle layer that changes the shape of the lens for focusing.
Suspensory Ligaments
Fibrous tissues that connect the lens of the eye to the ciliary body, adjusting the lens shape for focusing.
Fovea
A small depression in the retina of the eye where visual acuity is highest, due to the high density of cones, and no rods.

Final Answer :
D
Explanation :
The ciliary muscle is responsible for changing the shape of the lens to adjust for distance vision. If Julie has trouble looking from close up to distance, it suggests that her ciliary muscles may not be working properly to adjust the lens shape for distance viewing.
