Answer
The function of the eyepiece lens is to magnify the real image formed by the objective lens. The eyepiece allows the viewer to see a larger and clearer image of the Moon by spreading the light rays further apart, which makes the image appear larger. The eyepiece effectively serves as the lens through which the observer views the image produced by the objective lens.
