It is equal to the reciprocal of the focal length of the device: P = 1/f. High optical power corresponds to short focal length. The SI unit for optical power is the inverse metre (m?1), which is commonly called the dioptre. Converging lenses have positive optical power, while diverging lenses have negative...
