| Abstract: | Purpose: To show an alternative interpretation for prism‐dioptre and access Prentice's rule accuracy. Methods: Algebraic calculation. Results: The prism‐dioptre can be expressed as a percentage of the distance between the prism and the plane of prismatic dislocation. Prentice's rule is an imprecise mathematical expression prone to expressive errors. Conclusions: The prism‐dioptre seems to be more informative when interpreted as a percentage. Prentice's rule is more effective as a pedagogical approach for introducing the concept of spherical lenses' prismatic image dislocation rather than a method for calculating its actual value.
