What term describes the eyes' ability to focus clearly on objects moving toward or away from the viewer?

Explanation:
Focusing on objects that are moving closer or farther away requires the eye to quickly adjust its lens to keep the image sharp. The speed at which the eye can make that adjustment describes how dynamic the focusing is, so “speed of focusing” best captures this ability. The other terms don’t fit: visual memory is about recalling what you’ve seen, visualization is forming mental images, and pursuit refers to the eyes tracking a moving object without changing focus.
