period. What is a dioptre? A dioptre (dpt) is the unit of measurement of the optical power of a lens. In the case of spectacle lenses, negative dioptre values correct short sightedness, positive values correct [...] light source oscillate in waves which are scattered in all directions. A polarisation filter in a spectacle lens filters out all oscillating light waves which are not vertical, so that only vertically oscillating [...] consist of a smooth, curved surface - but different concentric ring zones, which have different optical refractive properties. The lens is therefore significantly thinner with the equivalent refractive
