The value of the object distance at which the lens will act as a simple microscope is 25 cm.

What is the least distance of distinct vision?

The least distance of distinct vision is the smallest distance someone with "normal" vision can comfortably look at something.

The least distance of distinct vision of a microscope is 25 cm.

When the object is placed at focal length of 15 cm, a virtual, erect and magnified image will be formed at near point (D = 25 cm) from the eye.

Thus, the value of the object distance at which the lens will act as a simple microscope is 25 cm.
