The power of a lens is measured by opticians in a unit known as a diopter. A diopter is equal to the reciprocal of the focal length. diopters = 1/(focal length) A lens system with a focal length of 1.7 cm (0.017 m) is a 59-diopter lens. A lens system with a focal length of 1.59 cm is a 63-diopter lens.
