WebPower P P. The power P P of a lens is defined to be the inverse of its focal length. In equation form, this is. P = 1 f. P = 1 f. where f f is the focal length of the lens, which must be given in meters (and not cm or mm). The power of a lens P P has the unit diopters (D), provided that the focal length is given in meters.
