A lens with a short focal length indeed produces a higher power lens. The power of a lens is defined as the reciprocal of its focal length, measured in meters. Therefore, when the focal length is shorter, the resulting power calculation yields a larger value. This indicates that the lens has a stronger ability to converge or diverge light rays, which is a characteristic of a higher power lens.

In optics, higher power lenses are typically used in applications where strong magnification is required, such as in magnifying glasses or in certain types of microscopes. The relationship between focal length and power is fundamental in understanding how different lenses are utilized in optical devices.

The other choices discuss scenarios that do not correctly relate to the properties of a lens with a short focal length: a longer focal distance would imply a lower power, and a short focal length does not render a lens unusable in optics.
