The refraction measurement is a measurement with which the refractive error of the eye is determined. During the refraction measurement, the necessary correction is established: the spherical power (in diopters), the cylindrical power (in diopters), the axis direction (in degrees) for any cylindrical correction, the prism (in prism diopters) and any additional power of the reading area (in diopters), the so-called reading addition


The purpose of a refraction measurement is to determine the correction (through glasses or lenses) with which the patient can see optimally.

Patient Population

Adults and children from the age that they can interpret a picture chart.
