Abstract

A device and computer program for determining the spherocylindrical refraction of an eye are disclosed. A component having adjustable optics is provided, the refractive power of which can be adjusted via a refractive power adjustment device. The spherocylindrical refraction is then determined from the adjustment of the refractive power adjustment device at different orientations of a typical direction of the optics or a typical direction of eye test characters.
