How does the eye change in order to focus on near or distant objects?�

1.	How does the eye change in order to focus on near or distant objects? A. the lens moves in or out B. the retina moves in or out C. the lens becomes thicker or thinner D. the pupil becomes larger or smaller
Answer» C. the lens becomes thicker or thinner The shape of the lens is changed by ciliary muscles so that the image forms at a sharp focus at the retina. The lens becomes thicker to focus at near objects and becomes thinner to focus at distant objects.
