If a plus lens is moved away from the eye, what occurs to its perceived power?

When a plus lens is moved away from the eye, its perceived power decreases. This is due to the concept of lens magnification and the way that distance affects the effective strength of the lens. As the distance between the lens and the eye increases, the effective curvature of the lens as perceived by the eye diminishes. The eye sees the lens as having less converging power because the light rays diverge more by the time they reach the eye, which leads to a reduction in the perceived lens power.

In the context of optics, particularly with plus lenses which are converging, moving the lens further away leads to less convergence of the light rays entering the eye and an overall reduction in the eye's ability to focus clearly. Therefore, as a result of this physical and optical principle, the correct response highlights how the perceived power indeed decreases as the plus lens is situated farther from the eye.
