Lens Diopter Power. Because the power of a lens is proportional to unity (one) divided by. the diopter (d) is the si unit of lens power and is defined as one divided by the focal length of the lens measured in meters. You might have seen the term. It is common to specify the dioptric power of prescription glasses, for example, whereas the focal length is usually specified for standard lenses, microscope objectives and photographic objectives. And it is the measurement unit for an optical prescription. the dioptric power is measured in units of m −1, also called diopters (dpt). a diopter is a unit used to calculate the focusing strength of a pair of glasses or contact lenses. diopter, in optics, unit of magnifying power of a lens or lens system. They are made expressly to gauge. the basic unit of measurement in optometry, diopters, is used to express the optical power of prescription lenses.
